The DeWALT DCF887P2-QW 1/4" impact wrench delivers a balance of compact design and high torque for fastening and loosening tasks. With a maximum torque of 205 N⋅m, an idle speed up to 3250 RPM and an impact rate of 3800 bpm, the tool is engineered for efficient performance on automotive, assembly and maintenance jobs. The kit includes lithium-ion battery capacity that supports extended runtime while keeping the unit lightweight at approximately 1.56 kg, and the familiar DeWALT yellow and black finish provides clear visibility on-site.

Advantages

The impact wrench combines high torque output with a compact 1/4" anvil, enabling access in tight spaces without sacrificing power. A 5 Ah lithium-ion battery option provides prolonged operating time between charges and consistent power delivery. The tool offers reverse function for quick direction changes, and its light weight improves handling during overhead or extended use. The high idle speed and impact rate improve productivity on repetitive fastening tasks.

Suitable for

• Automotive repair and tyre changes where a compact high-torque tool is required
• Mechanical assembly and maintenance in workshops and production lines
• Construction and installation tasks in confined or hard-to-reach areas
• DIY projects that demand reliable cordless fastening

How to use

Before operation, ensure the battery is fully charged and correctly seated in the tool. Select the appropriate 1/4" socket and attach it securely to the anvil. Start at a lower speed or torque setting if available to prevent over-tightening, then increase as needed to reach the required tightness. Use the reverse control to remove fasteners. Maintain a firm two-handed grip or use the tool’s recommended stance to manage reaction torque during impact operation. After use, remove the battery and store the tool and battery in a dry, cool place.

Recommendations

For optimal results, match socket size and fastener grade to the torque capabilities of the impact wrench. Charge the 5 Ah battery according to manufacturer guidelines and allow cooling intervals during heavy use to preserve battery life and motor performance. Regularly inspect sockets and the anvil for wear and replace damaged accessories. Personal protective equipment such as eye protection and hearing protection is advised when operating impact tools.
