Power, Mobility, and Productivity Without Air Hoses

Cordless impact wrenches have become one of the fastest-growing fastening technologies in industrial maintenance and manufacturing. Advances in lithium-ion battery technology and brushless motors now allow cordless tools to deliver power levels that rival many pneumatic impact wrenches while providing the freedom to work without compressed air or power cables.


For many manufacturers, the transition from pneumatic to cordless tools is driven by more than convenience. Eliminating air hoses reduces workstation clutter, improves operator mobility, lowers infrastructure costs, and simplifies production layouts. As battery technology continues to improve, cordless impact wrenches are becoming the preferred solution for both maintenance operations and production assembly.

The Shift from Pneumatic to Cordless


For many years, pneumatic impact wrenches dominated automotive assembly lines because they offered high power, low weight, and reliable performance.
 Today, however, many manufacturers are replacing pneumatic tools with cordless alternatives.


Cordless systems eliminate the need for compressors, air piping, filters, lubricators, and hose maintenance while giving operators complete freedom of movement. They also reduce trip hazards, simplify workstation reconfiguration, and allow fastening operations to be performed more efficiently around large products or moving production lines.


As factories continue to modernize, cordless fastening is becoming an increasingly attractive investment for both new production facilities and factory upgrades.

Professional Cordless Tools in Manufacturing


One interesting trend in today’s manufacturing environment is the growing use of professional cordless impact wrenches on production lines.


Brands such as Milwaukee and Bosch Professional were originally developed for construction and industrial maintenance, but many automotive and general manufacturing companies now use them for production assembly because they offer excellent performance at a competitive price.


In particular, these tools are commonly used for fast screw seating or for applications where moderate torque repeatability is acceptable.
Their significantly lower purchase cost compared with dedicated industrial cordless fastening systems makes them an attractive solution for manufacturers seeking to improve productivity without making a large capital investment.


While they cannot match the torque consistency or process control of industrial shutoff or transducerised tools, professional cordless impact wrenches continue to gain popularity because they provide an excellent balance between performance, durability, and affordability.

Industrial Cordless Impact Wrenches


For applications requiring better torque repeatability, some manufacturers offer industrial-grade cordless impact systems specifically designed for production assembly.


These tools typically operate over smaller, more controlled torque ranges and incorporate improved motor control, helping deliver more consistent tightening than general-purpose professional tools.


Although industrial cordless impact systems represent a higher initial investment, they are well suited to production environments where improved fastening consistency is required while maintaining the speed and mobility of cordless operation.

Cordless Shutoff Wrench


Consistent Torque Control for Production Assembly


Cordless shutoff wrenches combine the mobility of battery-powered tools with the torque consistency required for modern manufacturing. Unlike conventional impact wrenches, which rely on repeated hammering to generate torque, a cordless shutoff wrench uses a precision clutch mechanism that automatically disengages once the preset torque has been reached.

This automatic shutoff eliminates much of the variation associated with impact tools, allowing manufacturers to achieve more consistent tightening results while maintaining the flexibility of cordless operation.

For production environments where fastening quality is important but full digital traceability is not required, cordless shutoff wrenches provide an excellent balance between performance, repeatability, and investment cost.

From Impact Tightening to Controlled Fastening


Many manufacturers begin their cordless journey with professional impact wrenches because they are powerful, affordable, and easy to deploy.

As production quality requirements increase, however, torque consistency becomes increasingly important.

Unlike an impact wrench, which delivers torque through repeated impacts until the operator releases the trigger, a cordless shutoff wrench automatically stops when the preset torque is reached.
This significantly reduces operator influence and helps produce more consistent tightening results across multiple operators and production shifts.


For many automotive, electronics, and appliance manufacturers, cordless shutoff wrenches represent the natural next step toward standardized assembly processes.

Why Choose a Shutoff Wrench?


The automatic shutoff clutch offers several advantages over conventional impact tools:


  • Improved torque repeatability 
  • Automatic clutch shutoff at the preset torque 
  • Reduced dependence on operator judgment 
  • Lower risk of overtightening 
  • Better product quality 
  • Quiet, non-impact operation 
  • Lower vibration and improved operator comfort 
  • No compressed air infrastructure required 


The result is a fastening system that delivers consistent performance while remaining simple to operate.

Designed for Production Assembly

Cordless shutoff wrenches are particularly well suited to repetitive fastening applications where the same tightening operation is performed throughout the production shift.

Typical applications include:

  • Automotive assembly 
  • Electric vehicle components 
  • Home appliance manufacturing 
  • Consumer electronics 
  • Industrial equipment assembly 
  • Electrical products 
  • General manufacturing 

They are especially effective where manufacturers require consistent fastening quality but do not yet require torque data collection or full Industry 4.0 integration.

Cordless Shutoff Impact Wrench

High Torque Productivity with Automatic Shutoff Control


A cordless shutoff impact wrench builds upon the familiarity and productivity of a conventional cordless impact wrench by adding automatic torque cutoff. Rather than replacing the impact mechanism, the shutoff function stops the tool once the preset tightening torque has been reached, preventing unnecessary impacts after the desired torque is achieved.

This provides operators with a simple, intuitive fastening tool that offers better torque control and significantly reduces the risk of overtightening, while preserving the speed and ease of use that make impact wrenches so popular in production environments.

A Practical Upgrade from a Standard Impact Wrench


Many manufacturers already use cordless impact wrenches because they are powerful, portable, and require very little operator training.


However, because a conventional impact wrench continues impacting as long as the trigger is pressed, the final tightening torque depends heavily on the operator’s judgement. Different operators—or even the same operator at different times—may produce different tightening results.


A cordless shutoff impact wrench addresses this challenge by automatically stopping the tool once the preset torque has been reached. The operator continues to use the tool exactly as they would a standard cordless impact wrench, but with improved torque control and reduced variation between tightening cycles.


For manufacturers seeking a straightforward improvement in fastening quality without changing their production methods, this makes the cordless shutoff impact wrench an attractive upgrade.

Why Manufacturers Choose Cordless Shutoff Impact Wrenches

Unlike a transducerised fastening system, a cordless shutoff impact wrench does not require advanced programming, torque-angle monitoring, or extensive operator training.

Instead, it focuses on solving one of the most common production challenges: preventing excessive tightening while maintaining the speed and simplicity of an impact wrench.

Key benefits include:

  • Prevents overtightening
  • Better torque consistency than a conventional cordless impact wrench 
  • Familiar operation with minimal operator retraining 
  • High fastening speed 
  • Excellent portability

Cordless Shutoff Impulse Wrench

The Next Evolution of Cordless Production Fastening

A cordless shutoff impulse wrench combines the low reaction force of hydraulic impulse technology with the convenience of cordless operation and the protection of automatic torque cutoff.
Unlike conventional impact wrenches, which generate torque through repeated hammering, an impulse wrench uses a hydraulic pulse mechanism to deliver smooth, controlled tightening with significantly lower reaction force transmitted to the operator.

For manufacturers seeking to replace pneumatic pulse tools without sacrificing ergonomics or productivity, cordless shutoff impulse wrenches provide one of the closest cordless alternatives available today.

Built on a Proven Fastening Technology


Hydraulic impulse fastening has been trusted in automotive assembly for decades.

Manufacturers such as URYU, Yokota (including Rami Yokota in Europe), and AIMCO have established impulse technology as the preferred solution for many repetitive assembly applications where operator comfort and fastening productivity are equally important.


Rather than replacing this technology, cordless shutoff impulse wrenches extend the same fastening principles into a battery-powered platform, eliminating the need for compressed air while maintaining the low reaction characteristics that have made pneumatic pulse tools so successful.

Why Is This Technology Gaining Interest?


For many years, cordless shutoff impulse wrenches saw limited adoption because they were significantly larger, heavier, and more expensive than cordless shutoff impact wrenches.

As a result, many manufacturers selected cordless shutoff impact tools as their first step away from pneumatic systems.

More recently, however, manufacturers have begun to recognize some of the practical limitations of cordless shutoff impact technology.


Although shutoff impact tools offer improved torque control compared with conventional impact wrenches, they still generate noticeable reaction force during tightening. At higher production volumes, this can contribute to increased operator fatigue, particularly on repetitive assembly stations.


Manufacturers replacing pneumatic pulse tools have also found that cordless shutoff impact wrenches often cannot replicate the same combination of tightening speed and operator comfort that they were accustomed to.


These changing production requirements have renewed interest in cordless shutoff impulse technology, particularly within automotive assembly.

Lower Reaction Force, Better Operator Comfort

The primary advantage of a cordless shutoff impulse wrench is not higher torque accuracy.
Its greatest benefit is operator ergonomics.

Because torque is generated through a hydraulic impulse mechanism rather than repeated mechanical impacts, reaction force transmitted to the operator is significantly reduced.

This provides several practical advantages:

  • Reduced operator fatigue 
  • Improved comfort during repetitive assembly 
  • Better tool control 
  • Lower physical strain 
  • Improved productivity over long production shifts 

For applications involving hundreds or thousands of tightening cycles per day, improved ergonomics can be just as valuable as improvements in fastening performance.

Dupas PWN Series

The Dupas PWN Series brings hydraulic impulse fastening into a modern cordless platform.
It combines:

  • Hydraulic impulse technology 
  • Automatic torque cutoff 
  • Brushless motor technology 
  • Cordless mobility 
  • Industrial-duty construction 
  • Consistent production performance

The automatic torque cutoff prevents unnecessary tightening after the target torque has been achieved, while the impulse mechanism minimizes reaction force throughout the fastening cycle.

The result is a fastening system designed specifically for continuous production environments where operator comfort and productivity are critical.

Typical Applications

Cordless shutoff impulse wrenches are particularly suited to:

  • Automotive assembly 
  • Electric vehicle manufacturing 
  • Commercial vehicle production 
  • Appliance manufacturing 
  • Industrial equipment assembly 
  • Continuous production lines 
  • High-cycle fastening operations 

They are especially valuable where operators perform repetitive tightening throughout an entire production shift.

Is a Cordless Shutoff Impulse Wrench Right for You?


A cordless shutoff impulse wrench is an excellent choice when your production requires:

  • Low reaction force 
  • Improved operator ergonomics 
  • Fast production tightening 
  • Better torque control than a conventional impact wrench 
  • Cordless mobility 
  • Replacement of pneumatic pulse tools 
  • High-volume repetitive assembly 

While these tools typically represent a higher investment than cordless shutoff impact wrenches, many manufacturers find that the improvements in operator comfort, productivity, and production consistency justify the additional cost in demanding assembly environments.

Cordless Intelligent Wrench (Transducerised)

Intelligent Cordless Tightening with Traceability and Flexible Process Control

Cordless intelligent wrenches combine the mobility of battery-powered fastening with the advanced process control traditionally associated with transducerised assembly systems. By integrating a torque transducer, electronic motor control, and wireless communication, these tools provide real-time torque measurement, tightening verification, and digital traceability without requiring a permanently connected controller.

As manufacturers continue to digitalize their production lines, cordless intelligent wrenches are emerging as a practical solution for applications that require greater process control than conventional shutoff tools while maintaining the flexibility of cordless operation.

A New Generation of Cordless Fastening


For many years, manufacturers had two distinct choices. Conventional cordless shutoff tools offered portability and consistent tightening, while transducerised nutrunners provided the highest level of process control, traceability, and programmable tightening strategies.


Cordless intelligent wrenches are creating a new category between these two technologies.
By integrating torque measurement directly into the tool, they provide tightening verification, programmable torque settings, and wireless communication while remaining completely cordless.


Although this technology is still evolving, it is attracting growing interest from manufacturers looking to improve quality without investing in a fully integrated tightening system.

Flexible Torque Settings


Unlike mechanical shutoff tools that require manual adjustment when torque values change, electronically controlled cordless intelligent wrenches can store multiple tightening programs.


On wireless models, the active tightening program can be selected automatically by an external trigger from a PLC, barcode scanner, operator guidance system, or MES.


This allows a single tool to perform multiple fastening operations with different torque settings throughout the production process, reducing the number of tools required at each workstation and minimizing the risk of incorrect torque selection.

Bridging Two Technologies


Cordless intelligent wrenches are not intended to replace high-end transducerised nutrunner systems from manufacturers such as Atlas Copco, Desoutter, Cleco, or ESTIC.


These systems continue to provide the highest level of tightening strategy control, multi-step tightening, torque-angle analysis, advanced process monitoring, and integration for demanding production environments.


Instead, cordless intelligent wrenches offer manufacturers an attractive intermediate solution. They deliver many of the advantages of transducerised fastening—including torque verification, traceability, and programmable process control—in a portable cordless format, making them particularly suitable for lower-torque assembly applications where the complexity of a full nutrunner system may not be justified.

An Emerging Technology


Cordless intelligent fastening is one of the fastest-evolving areas of industrial assembly.


Performance continues to improve as manufacturers develop more compact transducers, more powerful battery platforms, and increasingly sophisticated wireless communication systems.


While the technology is not yet as mature as established corded transducerised nutrunners, its capabilities continue to expand rapidly. As manufacturing places greater emphasis on digital quality control and flexible production, cordless intelligent wrenches are expected to play an increasingly important role in modern assembly operations.

Typical Applications


Cordless intelligent wrenches are particularly suited to:


  • Automotive assembly 
  • Electric vehicle manufacturing 
  • Automotive components 
  • Electronics assembly 
  • Home appliances 
  • Industrial equipment 
  • Flexible production cells 
  • Mixed-model assembly lines 
  • Stations requiring multiple torque settings

Cordless DC Tool High-Volume Automated Production Very High Yes

DUPAS NPA and NRA Series


Intelligent Cordless Tool Features

The Dupas cordless intelligent wrench platform combines precision torque measurement with practical features designed for everyday production use. Rather than functioning as a simple power tool, the system provides operators with real-time tightening feedback while giving production engineers greater flexibility in managing fastening processes.

Real-Time Torque & Angle Measurement
An integrated torque transducer continuously measures each tightening cycle, allowing the tool to display actual torque and angle values in real time rather than estimating the result from motor current or clutch settings.

This provides immediate confirmation of every fastening operation and forms the foundation for tightening verification and digital traceability. 



Multiple Tightening Programs

Each tool can store up to eight programmable tightening strategies, allowing a single wrench to perform multiple fastening operations without manual torque adjustment.

This significantly reduces the number of tools required at a workstation and minimizes setup time when assembling products with different torque specifications. 

Wireless Production Integration (iNPA & iNRA)
Wireless models such as the iNPA and iNRA extend the capability of the standard cordless intelligent wrench by communicating directly with production systems.

Different tightening programs can be selected automatically through external triggers from PLCs, barcode scanners, MES systems, or operator guidance software. Tightening results can then be transmitted wirelessly for production monitoring and traceability.

This allows manufacturers to perform multiple fastening operations using a single tool while maintaining automatic process control and reducing the possibility of incorrect torque selection.

Built for Continuous Production


Both the NPA and NRA Series are designed for demanding industrial environments and include features that improve productivity throughout the working day, including:


  • Brushless motor for longer service life

Cordless Torque Multiplier


Portable High-Torque Bolting Without Hydraulic or Pneumatic Systems

Many industrial bolting applications require tightening torques far beyond the capability of conventional cordless impact wrenches. Traditionally, these jobs have relied on hydraulic torque wrenches, pneumatic torque multipliers, or manual gear multipliers, often requiring compressors, hydraulic pumps, hoses, or considerable physical effort.


The Dupas GWC Series offers a practical alternative by combining a high-ratio planetary gearbox with a battery-powered drive system, delivering controlled high torque in a completely cordless package.


Designed for general industrial bolting rather than precision production assembly, the GWC Series enables operators to perform high-torque fastening quickly, safely, and with minimal equipment.

Built for Industrial Bolting


Unlike cordless fastening tools designed for automotive production lines, the GWC Series is engineered specifically for heavy-duty bolting applications.


Its primary objective is to provide a portable solution for tightening and loosening large fasteners in the field, where mobility and convenience are often more important than the high precision required in assembly manufacturing.

With torque capacities ranging from 50 Nm to 2,500 Nm, the GWC Series covers a wide range of industrial bolting applications while eliminating the need for hydraulic pumps or compressed air.

Portable Alternative to Hydraulic Torque Tools


High-torque fastening has traditionally required bulky support equipment.


Hydraulic systems require pumps, hoses, couplings, and regular maintenance. Pneumatic systems require compressed air infrastructure and long air hoses.

A cordless torque multiplier simplifies the entire process by integrating the drive system into a compact battery-powered tool.

This allows operators to:


  • Move easily between work locations 
  • Reduce setup time 
  • Eliminate hoses and hydraulic pumps 
  • Improve accessibility in confined or elevated work areas 
  • Perform field maintenance more efficiently 


For many maintenance and installation tasks, portability can significantly improve productivity.

Current-Controlled High Torque


The Dupas GWC Series uses current-controlled motor technology to regulate tightening output rather than the torque transducer systems used in production assembly nutrunners.


This design is well suited to general industrial bolting, where the objective is controlled and repeatable tightening of large fasteners rather than precision torque-angle measurement or production traceability.

The tool also provides visual status indication, including:


  • OK 
  • NOK 
  • Reverse 
  • Low battery warning 
  • Battery replacement indication 


These features help operators monitor tool status during field operation. 

Typical Applications

The GWC Series is designed for high-torque fastening in industrial environments such as:
