DEWALT DCF899N-XJ 18V XR Brushless 1/2-Inch Detent-Pin High-Torque Impact Wrench

The DEWALT 18V XR Brushless 1/2-Inch Detent-Pin High-Torque Impact Wrench is a cordless model intended for demanding fastening and loosening work in automotive, construction, maintenance, and heavy-duty assembly. It runs on the DEWALT 18V XR battery platform, which suits users who already own these batteries. Maximum fastening torque is rated at 950 N⋅m, reflecting its tightening strength. This output is aimed at large or tightly secured fasteners rather than light screwdriving. Its cordless design means no mains connection is needed during use.

At 3.3 kg, handling and fatigue are worth considering during extended or overhead work. The 1/2-inch square drive uses a detent pin to retain compatible sockets. Three speed settings, together with adjustable torque, allow output to be matched to different fastening tasks. The built-in LED illuminates the working area, and the soft-grip handle aids controlled handling. It is powered by a removable lithium-ion battery pack. This tool-only package does not include a battery, charger, or carrying case.

• Up to 1,625 N⋅m of loosening torque for removing tight, seized, or over-torqued fasteners.
• Maximum no-load speed of 1,900 RPM.
• Impact rate of up to 2,400 impacts per minute.
• Supports fastening applications up to M20.
• Reverse rotation allows bolts and nuts to be loosened.
