This Bosch combination kit includes two (2) 18 V tools designed to provide professional cordless drilling and driving performance. The GDX18V-1600 2-in-1 impact driver is equipped with a mandrel that combines a 1/4" quick-change hex shank with power groove for bits with a 1/2" square drive for sockets. The motor delivers a torque of 1600 in/lb. The Compact Tough drill/driver features an upgraded 1/2" metal chuck and its motor delivers the same power as a conventional 18 V motor while offering a more compact size, which is convenient for hard-to-reach locations. It generates a torque of 600 in/lb and features 2 drilling speeds: from 0 to 1,900 RPM for high speed or 0 to 500 RPM for high power. Both tools are equipped with built-in LED lighting that greatly enhances visibility in darker areas. This kit includes 2 SlimPack 18V 2.0 Ah batteries, a charger and a carrying bag.
