Draper D20 20V Brushless Impact Wrench, 1/2" Sq. Dr., 250Nm (Sold Bare)

The Draper D20IW250 is a powerful 20V cordless impact wrench designed for heavy-duty fastening and removal of nuts and bolts across automotive, construction, and engineering applications. Delivering 250Nm of maximum torque through a high-performance brushless motor and twin hammer mechanism, it tackles wheel nuts, structural bolts, and seized fixings with the kind of force that makes short work of demanding jobs.

Sold as a bare tool and powered by Draper's D20 20V Li-ion battery platform, the D20IW250 is an efficient addition for anyone already invested in the D20 system. Compact at just 1.1kg bare weight, ergonomically designed with a soft grip handle, and fitted with a belt clip for hands-free portability, this wrench is built to perform in workshops, on site, and under vehicles alike.

Key Features & Benefits:

Brushless Motor Technology
The high-performance brushless motor delivers greater efficiency and a longer service life than brushed alternatives, running cooler under sustained load and drawing less current from the battery per cycle. For workshop and site professionals using this tool regularly, that means extended runtime, reduced maintenance, and a lower total cost of ownership.

250Nm Maximum Torque
With 250Nm of maximum torque — significantly more than a standard impact driver — the D20IW250 is built for serious fastening tasks. Wheel nuts, M12 and M16 structural bolts, machinery fixings, and heavily torqued fasteners are all within its capability, making it a genuine workhorse for automotive and construction applications.

Twin Hammer Mechanism
The twin hammer impact system delivers torque in smooth, consistent pulses rather than a single hard strike, reducing stress on both the fastener and the tool. The result is more controlled, efficient energy transfer — particularly beneficial when working with socket sets on precision applications such as brake components or engine fixings.

1/2" Square Drive
The industry-standard 1/2" square drive accepts the full range of 1/2" impact sockets — deep, shallow, metric, and imperial — as well as socket adaptors, making this wrench compatible with the socket sets most professionals and serious DIYers already own.

Variable Speed Control
The variable speed trigger allows you to modulate torque output from low-speed positioning through to full-power driving, giving you the control to run down nuts smoothly before applying full torque — or to ease fasteners loose before full-speed extraction.

Forward/Reverse Switch
The easily accessible forward/reverse switch makes switching between tightening and loosening operations quick and intuitive — essential when removing and refitting multiple fasteners on the same component.

Ultra-Bright LED Worklight
The integrated LED worklight activates during use, illuminating the drive socket and fastener in poorly lit conditions — whether working in an engine bay, under a vehicle on axle stands, or in a dimly lit plant room or roof space.

Ergonomic Soft Grip Handle
The contoured soft grip reduces vibration transmission and hand fatigue during extended use, improving both comfort and control when torquing multiple fasteners in sequence.

Belt Clip for On-Site Portability
The built-in belt clip secures the wrench to your belt or tool belt between fixings, keeping both hands free for positioning components and reducing the risk of the tool being set down and misplaced on a busy site or workshop floor.

Ideal Applications:

The D20IW250 is particularly well suited to:

• Wheel nut removal and refitting — automotive servicing and tyre changes
• Structural steel fastening — M12/M16 bolts in construction and fabrication
• Plant and machinery maintenance — removing and refitting high-torque fixings
• Decking and landscaping — driving large lag screws and coach bolts
• General assembly and disassembly — any task requiring repeatable high-torque fastening

Battery & Compatibility:

The D20IW250 runs on any D20 20V Li-ion battery — 1.5Ah, 2.0Ah, 3.0Ah, or 4.0Ah — from Draper's interchangeable D20 cordless tool range. If you already own D20 batteries from a drill, circular saw, or other D20 tool, this wrench integrates into your existing setup without any additional battery investment. Batteries and chargers are sold separately.

How It Compares to the D20 Impact Driver:

Both the D20ID180 impact driver and D20IW250 impact wrench share the same D20 battery platform, brushless motor technology, and twin hammer mechanism — but they serve different purposes. The impact driver (180Nm, 1/4" hex) is optimised for screwdriving and wood fixings. The impact wrench (250Nm, 1/2" sq. dr.) is built for nuts, bolts, and socket-based fastening — particularly in automotive and structural applications where higher torque and socket compatibility are essential.

Specification Summary:

Warranty:

The Draper D20IW250 is backed by a 24-month manufacturer's warranty as standard. Register your tool with Draper to extend coverage to 36 months at no additional cost — giving you an extra year of manufacturer-backed protection on your investment.

Does the Draper D20IW250 come with a battery and charger?
No — the D20IW250 is sold as a bare tool. D20 20V Li-ion batteries and chargers are available separately, or any existing D20 battery from the Draper D20 range can be used directly.

What size sockets does the Draper D20 impact wrench accept?
The D20IW250 uses a 1/2" square drive, compatible with the full range of standard 1/2" impact sockets — metric and imperial, deep and shallow — as well as 1/2" socket adaptors.

What is the difference between the Draper D20 impact wrench and impact driver?
The impact driver (D20ID180) uses a 1/4" hex chuck and delivers 180Nm of torque — ideal for screwdriving and wood fixings. The impact wrench (D20IW250) uses a 1/2" square drive and delivers 250Nm — designed for nuts, bolts, and socket-based fastening in automotive and structural applications.

Can the Draper D20IW250 remove wheel nuts?
Yes — with 250Nm of maximum torque and a 1/2" square drive, the D20IW250 is well suited to wheel nut removal and refitting for cars and light commercial vehicles when used with appropriate impact sockets.

Is the Draper D20 impact wrench compatible with all D20 batteries?
Yes — the D20IW250 accepts any D20 20V Li-ion battery regardless of capacity, and is fully interchangeable with all other tools in the Draper D20 cordless range.
