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

The GRS 004-875 Quick Change tool holder is designed specifically for 1/8" (3.18 mm) round shank gravers, offering a streamlined single hex screw clamping design that keeps smaller-diameter tools firmly secured. Sold individually, this QC holder is ideal for engravers who work primarily with 1/8" diameter gravers and want quick, reliable tool changes without the bulk of a two-screw setup.

Unlike traditional GRS QC tool holders — which use two hex screws and feature a 0.136" (3.45 mm) inside diameter hole — this holder requires only one hex screw to lock 1/8" shank tools securely in place. The shaft diameter of 0.250" (6.32 mm) is consistent across all GRS QC tool holders, ensuring full compatibility with the GRS quick change handle system.
