The GRS 004-855 Quick Change tool holder is designed specifically for 3/32" (2.35mm) round shank gravers and engraving tools. Unlike traditional QC holders that use two hex screws and a larger 0.136" (3.45mm) bore, this holder features a single hex screw securing mechanism sized precisely for the popular 3/32" tool diameter — providing a secure, accurate fit without the need for a second fastener. The holder's 0.250" (6.32mm) diameter shaft is standard across all GRS QC tool holders, ensuring seamless compatibility with the GRS quick change system. Sold by the piece.
