3M 7100006569 Cubitron Ii Roloc 984F Disc 4 Inch 80 Grit

Product Description

The 3M 7100006569 is a Cubitron II Roloc 984F coated abrasive disc engineered for medium to high pressure grinding where a compact disc size is required. Built around 3M Precision-Shaped Grain (PSG) technology, the disc maintains consistently sharp cutting points that remove material faster with less applied pressure compared to conventional abrasive grains. The 2-ply backing adds structural rigidity for edge grinding work, and an integrated grinding aid reduces heat buildup during use on heat-sensitive alloys. At 4 inches in diameter with 80 grit, this disc is sized for handheld right-angle grinders used in fabrication and finishing operations.

This disc is designed for grinding stainless steel, cobalt chrome, and nickel alloys in applications where thermal control and cut rate are both critical. Typical use cases include weld removal, edge blending, and surface prep on fabricated components. The compact 4-inch format suits confined workspaces and detail grinding tasks that larger discs cannot reach efficiently. The Roloc quick-change attachment system allows fast disc swaps between grits or disc types without tools, reducing downtime during multi-step grinding sequences.

Key Features

• Precision-Shaped Grain (PSG) maintains sharp cutting points for faster stock removal with less pressure
• Integrated grinding aid minimizes heat generation on stainless steel and other heat-sensitive alloys
• 2-ply backing construction supports medium to high pressure grinding and edge work
• Roloc quick-change attachment system enables tool-free disc changes between grades or applications
• 80 grit designation suited for aggressive material removal and weld grinding
• Coated abrasive construction delivers extended disc life and more parts completed per disc

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders accepting 4-inch quick-change discs. Best suited for stainless steel, cobalt chrome, and nickel alloy workpieces in fabrication and manufacturing environments.

Installation Notes

This disc is installed and serviced by metalworking fabricators and industrial maintenance technicians. Before mounting, verify the grinder spindle speed rating meets or exceeds the maximum rated speed of the disc. Ensure the Roloc mandrel is fully seated and locked before operation. Wear appropriate PPE including a face shield and grinding gloves, and confirm the workpiece is securely clamped before beginning the grinding pass.
