MILWAUKEE® Introduces New Range of M12 FUEL™ Sub-Compact Impact Wrenches

MILWAUKEE® continues to drive innovation in cordless impact wrenches with the introduction of the M12 FUEL™* Sub-Compact Impact Wrenches.

Bridging the gap between ratchets and standard imact wrenches, this sub-compact lineup is ideal for aftermarket mechanics and auto body techs to complete ant light duty work including bumpers, fenders, engine work, brake callipers, and suspension.

Available in 1/4" and 3/8", these M12 FUEL Sub-Compact Impact Wrenches solve common size, weight and productivity frustrations. These solutions excel in both performance and size, offering a lightweight solution to reduce user fatigue while fitting into the tightest spaces without additional extensions, swivels, or adapters.  A 4-Mode Drive Control system offers precision and adaptability, including an auto shut-off mode that limits torque for hand-tight applications and a bolt removal mode that slows RPM to prevent fastener drops.

Built for precision work in the tightest spaces, the M12 FUEL 1/4" Sub-Compact Impact Wrench with Friction Ring delivers up to 95 Nm of fastening and 136 Nm of nut-busting torque. At just 112 mm in length and 0.86 kg it offers the lightest weight and best under hood access in its class. With fast application speeds, this solution maximises productivity without sacrificing control.

4-Mode DRIVE CONTROL allows the user to shift into four different speed and torque settings.

Delivering up to 271 Nm of fastening and 305 Nm of nut-busting torque, the M12 FUEL 3/8" Sub-Compact Impact Wrench with Friction Ring is the go-to for light-duty applications that demand power in tight spaces. Measuring just 114 mm in length and weighing only 0.91 kg, this solution provides access in the most confined spaces while minimising user fatigue.

 

MILWAUKEE® is committed to improving productivity by providing performance driven and trade focused solutions so users can perform an entire day’s work on one battery system. The new M12 Impact Wrenches are fully compatible with the entire M12line, now offering more than 125 power tool solutions.

 

*M12 FUEL power tools are designed, engineered, and built to deliver extreme performance and productivity. All M12 FUEL products feature three MILWAUKEE® exclusive innovations—the POWERSTATE Brushless Motor, REDLITHIUM Battery Pack and REDLINK PLUSIntelligence Hardware and Software—that deliver unmatched power, run time and durability on the jobsite. Simply put, M12 FUEL tools are the most powerful sub compact cordless tools in their class.
