Our take on the Milwaukee 3450-20 M12 Subcompact Brushless 1/4" Hex Impact Driver

The Milwaukee 3450-20 is a 12-volt cordless impact driver built for tight spaces. It is 4.3 inches long, 2.0 inches wide and 1.7 pounds with battery, making it one of the smallest drivers in its class. The brushless motor delivers 1,100 in-lbs of torque and up to 3,000 RPM, and an internal metal gearcase adds durability. It uses M12 REDLITHIUM batteries, which are sold separately, and fits the wider M12 system of over 150 tools. It suits cabinet installers, electricians and anyone driving fasteners overhead or in cramped spots; it trades outright power for size against 18-volt drivers.

Questions and answers

Does the 3450-20 come with a battery?
No. The tool ships with the impact driver and a belt clip only. You need an M12 REDLITHIUM battery and charger, sold separately.
How does it compare with the M12 Fuel impact driver?
The Fuel version has more torque and drive modes. The 3450-20 is smaller and lighter, so it is the better pick when access matters more than power.
Will it drive deck screws or lag bolts?
It handles small to medium fasteners well. For long deck screws or lag bolts, an 18-volt driver is the better tool.
What bits does it take?
It has a 1/4-inch hex chuck, so it takes standard 1/4-inch hex driver bits and bit holders.

Any Milwaukee M12 REDLITHIUM battery fits, including the compact 2.0 Ah and larger packs. REDLINK electronics manage the power delivery.
