3M 7010328291 Quick-change Disc 36 Grit Ceramic 2 in

Product Description

The 3M 7010328291 is a ceramic-abrasive quick-change disc designed for high-speed grinding, blending, and surface preparation on metal. Part of the 3M 777F series, it uses a Type S (Roloc TS) attachment system that locks onto compatible right-angle grinder mandrels with a simple push-and-twist motion. The disc is 2 inches in diameter, carries a 36-grit very coarse cut rating, and is rated for a maximum of 25,000 RPM. The orange polyester cloth (YF-weight) backing delivers flexibility and durability under aggressive stock-removal conditions. This disc is sold individually but requires a minimum order quantity of 50 units.

This disc is suited for weld blending, rust and scale removal, edge deburring, and prep work ahead of coating or inspection. The ceramic abrasive grain self-sharpens under pressure, maintaining cut rate longer than aluminum oxide on steel, stainless, and hard alloys. It is commonly used by fabricators, pipefitters, ironworkers, and maintenance mechanics working on structural steel, pipe, and sheet metal assemblies where a compact 2-inch profile allows access to tight weld joints and confined areas.

Key Features

• Ceramic abrasive grain for aggressive, self-sharpening cut on metal
• 36 grit very coarse grade optimized for rapid stock removal and weld blending
• Type S (Roloc TS) quick-change attachment for fast disc swaps without tools
• 25,000 RPM maximum speed rating for compatibility with high-speed die and angle grinders
• YF-weight polyester cloth backing resists tearing under flexing and pressure
• Compact 2-inch diameter reaches restricted weld zones and tight corners

Compatibility

Designed for use with right-angle grinders and die grinders fitted with a Type S (Roloc TS) quick-change mandrel. Verify mandrel type before ordering, as Type S discs are not interchangeable with standard Roloc (Type R) mandrels.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and unplugged or the pneumatic supply disconnected. Confirm the grinder spindle speed does not exceed 25,000 RPM before mounting the disc. Inspect the disc for damage before each use and discard any disc showing cuts, tears, or delamination. Eye protection, a face shield, and appropriate respiratory protection are required when operating grinding discs per ANSI Z87.1 and applicable shop safety standards.
