3M 7100096553 Cubitron Ii Roloc Fibre Disc 36 Grit 4 Inch

Product Description

The 3M 7100096553 is a coated abrasive fibre disc engineered for heavy-duty metalworking operations including weld grinding, beveling, and flame-cut edge clean-up. Built on a stiff fiber backing with a strong resin bond, this 4-inch disc runs 36-grit Precision-Shaped Grain that maintains sharp cutting points under load. The result is faster stock removal with less operator pressure compared to conventional abrasive grain. It is primarily installed and used by welders, fabricators, and metal finishing trades working with ferrous and non-ferrous alloys.

This disc is suited for demanding fabrication environments where heat buildup is a concern. The grinding aid integrated into the disc construction reduces grinding temperatures, making it appropriate for heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. The Roloc attachment system allows fast disc changes when swapping between grits or moving to blending steps. Typical applications include structural steel fabrication, pipe weld prep, and heavy plate work in both shop and field settings.

Key Features

• Precision-Shaped Grain maintains sharp cutting points for fast material removal with reduced pressure
• Cooler-running grain minimizes metal discoloration, oxidation, and heat-related stress cracking
• Integrated grinding aid controls grinding temperatures for use on stainless steel, nickel alloys, and titanium
• Stiff fiber backing and strong resin bond provide tear resistance under high-pressure weld grinding
• Roloc attachment system enables quick disc changes between grades and applications
• Extended disc life reduces change frequency and increases parts completed per disc

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc holders. Suitable for weld grinding, beveling, and flame-cut edge clean-up on ferrous and non-ferrous metal substrates.

Installation Notes

Mounting is performed by pressing the Roloc disc onto a compatible threaded disc pad until it locks. Verify the grinder RPM rating does not exceed the disc maximum rated speed before use. Always wear appropriate eye and face protection when operating grinding discs. Inspect the disc for damage before each use and discard any disc that shows tears, cracks, or delamination.
