Specifications

Notes

GRS makes several QC tool holder variants — understanding the differences helps ensure you select the correct holder for your application:

• Traditional QC holders (e.g., 104-806, 104-870, 104-803SS) use 2 hex screws and have a 0.136" (3.45 mm) inside diameter bore.
• Single hex screw holders (including this 111-541) use 1 hex screw and are available in several bore sizes: 3/32" (2.35 mm) — 104-855; 1/8" (3.18 mm) — 111-541 (this item) and 104-875; 1.8 mm — 104-872.
• 104-870 is a traditional 2 hex screw holder with nylon ends for a "soft hit" in power tool applications.
• 104-856 is an extra-long version (½" longer than standard) with 2 hex screws and a 0.136" (3.45 mm) bore.
• All GRS QC tool holders share a 0.250" (6.32 mm) shaft diameter.
• These QC tool holders are intended for use with the GRS quick change handle 104-805 or GRS quick change handpieces such as the QC Magnum, QC Monarch, and QC 901.
