Keyless self-tightening drill chuck, clamping capacity

【Automatic Locking】The keyless locking mechanism automatically tightens using rotational inertia, securely holding bits even during high-speed drilling, without the risk of loosening.
【Wide Compatibility】This collet accepts round bits from 1/32 to 3/8 inch (0.8 mm to 10 mm), allowing you to quickly switch from a tiny drill bit to a larger twist bit on the same cordless drill.
【Suitable for Hex Shanks】Designed for standard electric drills and impact drivers, it transforms your cordless drill into a quick-change station for hex shank accessories.
【Anti-Slip Drill Bits】The internal jaws apply even pressure around the drill bit shank, reducing marks and deformation on specialty drill bits during demanding drilling applications such as metal or hardwood.
【Compact Sleeve】Its slim profile allows one-handed tightening in tight spaces, ideal for installing tall cabinets, automotive wiring or assembling flat-pack furniture.
