• Complete 6-Piece Master Set: Covers all common drill chuck pilot sizes ($4\\text{ mm}$ to $20\\text{ mm}$), ensuring you always have the right replacement key on hand.

• Forged Chromium Vanadium Steel: Heavy-duty Cr-V carbon steel construction resists bending, snapping, and gear tooth wear under high mechanical pressure.

• Precision-Machined Bevel Teeth: Machine-cut gear teeth interlock cleanly with chuck rings to deliver non-slip torque and protect chuck hardware from stripping.

• Rust & Corrosion Resistant: Coated in a protective anti-rust finish designed to withstand humid shop conditions, oils, and daily garage use.

2.Mesh Gear Teeth:Engage key teeth into the chuck\'s outer gear ring.

Insert the pilot pin completely into the chuck hole and align the key\'s bevel teeth with the gear teeth on the drill chuck collar.

3.Loosen & Insert Drill Bit:Twist T-handle counter-clockwise to open jaws and insert bit.

Rotate the T-handle counter-clockwise to open the chuck jaws. Place your drill bit shank centered inside the three jaws.
