The Milwaukee 2505-20 is a 12V cordless drill/driver built for tight spaces. Its four interchangeable heads — 3/8-inch chuck, offset driver, 1/4-inch hex and right angle — attach in 16 positions, so it reaches spots a standard drill cannot. A brushless POWERSTATE motor delivers up to 300 in-lbs of torque and 1,600 RPM, and the flat top and rear inline grip help with control and flush placement. It suits electricians, cabinet installers, HVAC and automotive techs who work in cramped areas; it trades outright power for access compared with full-size 18V drills.

Owners rate it highly and praise the access it gives in tight spots. Most criticism centers on the 12V power ceiling and the extra handling of swapping heads.
The Milwaukee M12 FUEL Installation Drill/Driver is a 4-in-1 drilling and driving tool built for hard-to-reach spaces. It comes with four dedicated heads: a 3/8" chuck, an offset driver, a 1/4" hex and a right angle. The heads attach in 16 different positions.
The tool has a slim profile and an inline grip at the back. The top is flat, so it can sit flush against a surface. A magnetic bit holder on the front holds multiple bits. The offset attachment reaches tight corners and does not damage or mar finished materials when fastening. The 1/4" hex, 3/8" chuck and offset attachments also connect to the right angle attachment for drilling and fastening at a right angle.
A POWERSTATE Brushless Motor delivers up to 300 in-lbs of torque and 1600 RPM. REDLINK Plus Intelligence protects the tool from overloading and overheating.
