High Precision Self-Tightening Bt30/40 Drill Chuck Tool Holder
A Self-Tightening Drill Chuck Tool Holder is a specialized toolholding device designed primarily for drilling operations. Its key feature is an internal mechanism that automatically increases its gripping force on the tool as the cutting torque increases during drilling. This "self-tightening" action helps prevent the drill bit from slipping or spinning inside the chuck, a common failure mode in standard drill chucks under high load.
