3M 7100076934 Cubitron Ii Roloc Disc 947A 120 Grit 3 Inch

Product Description

The 3M 7100076934 is a coated abrasive disc designed for edge grinding and surface finishing on metal and other hard materials. Built around 3M Precision-Shaped Grain, the disc delivers a sharp, cool, and consistent cut that holds up across extended use. The Roloc quick-change attachment system allows fast mounting and removal from compatible angle grinders and die grinders without additional hardware. At 3 inches in diameter and 120 grit, this disc is well-suited for fine stock removal and blending work where edge integrity and abrasive life both matter. A heavy X-weight poly-cotton backing resists tattering and fraying, making it a reliable choice for edge work in fabrication and metalworking environments.

This disc is used in metal fabrication shops, welding operations, and industrial finishing applications where consistent cut rate and disc longevity are priorities. The 120 grit rating positions it for fine grinding, light deburring, and surface blending rather than aggressive stock removal. The Roloc attachment is compatible with standard Roloc-style disc pads, making tool changeovers fast on the shop floor or in the field. It is typically handled by metal fabricators, welders, and maintenance technicians working on structural steel, pipe, and sheet metal components.

Installation Notes

Install onto a Roloc-compatible disc pad by pressing firmly and rotating until the disc locks into position.
