How to use

Fit the chuck to the drill spindle according to the drill manufacturer’s instructions, ensuring secure engagement with the spindle interface. Insert the drill bit into the chuck jaws to the required depth, then use the supplied chuck key in the gear teeth to tighten the jaws evenly. Confirm the bit is centered and firmly clamped before operation. To remove or change a bit, loosen the jaws with the key and extract the bit once it is free.

Usage recommendations

For best performance, verify compatibility between the drill chuck and the drill spindle, inspect the jaws and key for wear before use, and tighten the chuck fully with the key to prevent bit slippage. Use appropriate cutting speeds and lubrication for the material being drilled to extend chuck and bit life.
