1、High performance brushless motor optimizes machine\u0027s efficiency, increases 10X motor life and 50% more runtime of per charge when compared to brushed motor. Maximum 200Nm (2,655 in-lb) torque 10X more torque than the vast majority of drill driver in the market, easily fulfills your needs for processing a wide range of materials from screwing to metal or wood drilling and hole opening.In addition, brushless drills generate no friction or heat during use, and perform better and more smoothly. 2、20+3torque settings, 2 speeds(0-550RPM/0-2150RPM) adjustment, variable speed trigger and forward/reverse switch provide favorable force and precise control for driving in/out screws to prevent stripping, and drilling into wood, plastics, ice, metal and colorsteel with ease. Low torque with first speeds for screws driving and wood drilling. High torque with second speeds for wall drilling and hammer functions. 3、21V large capacity Lithium battery are powerful enough to keep the power drill constantly running for 10 hours when Non-loading. Indicator on the the front of the impact drill to display how many power left for less downtime on the job. 4、Compared with 3/8in plastic chuck, 1/2in auto-lock keyless metal ratcheting chuck is more stable and does not fall off and providing maximum accessory compatibility and durability. Trigger-activated LED Light in the drill front for increased visibility in enclosed workspaces and dark environment. 5、The compact drill with a soft rubber handle provides a comfortable grip for being breezily operated in one hand and perfectly reduce fatigue for long time use and easy access to tight areas. Come with an auxiliary handle to help you do heavy duty working, such as drilling a 1.25 meters thick ice holes. Screw Driver \u0026 Wall Drill \u0026 Hammer 3-in-1 working mode enable you to deal all works from light to heavy duty.
