The 73mm Impact Duty Shockwave Locking Bit Holder is a compact, heavy‐duty accessory for high‐torque screwdriving with impact drivers and drill drivers. Built from custom‐engineered steel, it is designed to withstand repeated impacts and tough site conditions while delivering a precise, secure hold on your bits and fixings.

An auto‐locking sleeve enables one‐handed bit changes, and dual internal magnets help to retain both bit and fastener.
