GRS 004-875 1/8" (3.18mm) Hole Quick Change "QC" Tool Holders-Sold by the Piece

A quick change tool holder grips a round shank graver and locks into the handpiece, so tools can be swapped without resetting the cut. The Glendo GRS 004-875 holder is made for 1/8" (3.18 mm) round shank gravers and uses a streamlined single hex screw clamping design that keeps smaller diameter tools firmly secured. It suits engravers who work mainly with 1/8" diameter gravers and want quick, reliable tool changes without the bulk of a two screw setup. Sold individually.

Traditional GRS QC tool holders use two hex screws and a 0.136" (3.45 mm) inside diameter hole. This holder needs only one hex screw to lock a 1/8" shank tool securely in place. Its 0.250" (6.32 mm) shaft diameter is consistent across all GRS QC tool holders, so it works with the GRS quick change handle system.
