The Milwaukee 3601-22CT is the most compact drill we compared. Milwaukee lists it at 5.7 in long and 3.2 lbs with the kitted battery, and the brushless motor delivers 550 in-lbs of torque across two speeds (0 to 550 and 0 to 1,700 RPM). An all-metal gear case and a 1/2 in metal chuck are aimed at jobsite durability, and the clutch has 13 settings. The kit includes two M18 REDLITHIUM CP2.0 batteries, a charger that takes both M18 and M12 packs, and a contractor bag, so you get a spare battery without paying extra. Milwaukee covers the tool for 5 years and the battery for 2, the longest tool warranty on this list alongside Bosch. Against that, Milwaukee's page shows no price, the 1,700 RPM top speed trails the Ryobi HP and DeWalt, and 13 clutch steps give less fine control for small screws.
