A hand-held drill bit sharpening tool includes a hand grip portion adapted to be held in a user's hand and a clamp on the grip portion adapted to hold a drill bit for sharpening the tip on a grinding wheel. The bit is held in the clamp by thumb pressure of the user. A sight on the grip portion allows visual alignment of the tip of the bit for proper sharpening of the cutting edges. The sight is adjustable to accommodate different drill bits. A guard is provided on the tool for protecting the user's hand from the grinding wheel.
