More Details

Ball bearings are designed to reduce friction in the tightening mechanism and provide a better grip on the drill. They are used for heavy-duty machining and require a key for tightening or loosening.
Keyed chucks are engineered to either loosen or tighten the hold on a tool by using a key. Keyed chucks offer the advantage of applying additional torque on the bit when slippage is a concern during heavy-duty applications.

FEATURES :
