GRS 004-858 Extra Long (1/2" Longer) Quick Change "QC" Traditional Tool Holders-Sold by the Piece

The GRS 004-858 Extra Long Quick Change Traditional Tool Holder is designed for engravers and stonesetting professionals who need additional reach beyond the standard-length QC holder. This holder is ½" longer than the standard 1" length, providing extra clearance and control in demanding applications. It is sold individually — one holder per purchase.

Traditional QC tool holders like this one are secured by 2 hex nuts and feature a 0.136" (3.45 mm) inside diameter hole — distinguishing them from other GRS QC holders that use only one hex nut and have different bore sizes. The shaft diameter is 0.250" (6.35 mm), consistent across all GRS QC tool holders.

This holder is compatible with the GRS quick change handle 104.805 and GRS quick change handpieces, including the QC Magnum, QC Monarch, and QC 901.
