BROWN Drill Chuck Key — 3/8 in (10 mm)
A replacement T-handle chuck key for keyed drill chucks, sized to fit 3/8 in (10 mm) chucks. The pinion gear engages the chuck's toothed collar so you can tighten and loosen the jaws securely by hand — essential for holding drill bits firmly and swapping them out. Hardened steel construction for long service life. Keep a spare on hand: a lost chuck key is the most common reason a keyed drill goes out of action.
Note: Chuck keys are sized to the chuck's pilot/pinion — confirm your chuck takes a 3/8 in key. This key does not fit keyless chucks.
