Special edition DeWalt x McLaren F1 Team 18V XR brushless 1/2" hog ring impact wrench. 1,396Nm fastening torque, 1,898Nm breakaway torque, 4-mode selector with Precision Wrench control. Supplied with 1x 5.0Ah battery, charger and TSTAK case.

The DCF99MP1T is the impact wrench from DeWalt's McLaren Formula 1 Team collaboration, and the spec sheet backs up the branding. 1,396Nm of fastening torque and 1,898Nm of breakaway torque put this firmly in the heavy-duty category. For context, that's enough force to handle wheel lugs, concrete anchor bolts, structural fixings, and most heavy mechanical fastening work without reaching for an air line.

The 1/2" hog ring anvil makes socket changes faster since you don't need to mess around with retaining pins. It's a detail that matters when you're switching between socket sizes frequently, particularly in automotive or plant maintenance work where you're moving between different bolt heads constantly.

Where this wrench really separates itself is the 4-mode membrane switch with Precision Wrench mode. The first three modes give you stepped power output for lighter through to heavy-duty applications. The Precision Wrench mode is the one worth paying attention to: it gives you finer control over fastening torque, reducing the risk of overtightening or thread stripping. If you're working to specific torque specs or dealing with fixings where overtorque could cause real problems, it's a genuinely useful feature rather than a gimmick.

A variable speed trigger provides additional control across all modes, and an adjustable bright white LED lights up the work area, which is worth having when you're working in plant rooms, under vehicles, or anywhere with limited natural light.

The brushless motor delivers the expected benefits of longer runtime per charge, less heat generation, and a longer service life compared to brushed equivalents. Supplied as a kit with a single 5.0Ah battery, multi-voltage charger, and TSTAK compatible carry case.
