The 12V Max GSR12V-300FC Chameleon Drill/Driver is a high-quality drill/driver with the 5-in-1 Flexiclick attachment system. It delivers 300 In.-Lbs. of torque and a max speed of 1,750 rpm, at only 1.2 Lbs. (tool only, not including battery). It starts with a magnetic bit holder for basic driving. The four attachments - a locking bit holder, a keyless chuck, an offset-angle and a right angle. The right-angle attachment is for tight spaces, and it works with all three other adapters.
