All bits are stored in a small plastic case with 10 compartments and clear size markings, helping prevent loss and allowing for easy identification. TIGHT 3-JAW CHUCK: Features a precisely designed 3-jaw chuck that securely holds bits from 0.8 to 3.0 mm, keeping them centered and upright for clean drilling.
