Milwaukee M12 Subcompact Brushless 1/4" Hex Impact Driver (Bare Tool) – Ultra-Compact & Lightweight

Overview

The Milwaukee M12 Subcompact Brushless ¼ Hex Impact Driver is designed to fit where larger drivers won’t. At just 4.3 inches long and 2.0 inches wide, this bare tool aims to reduce crowding in tight spaces while delivering solid performance for everyday fastening tasks. It’s built to be comfortable in hand, helping you maintain control through precise, steady drives.
