3M 7000045623 Abrasive Disc 36 Grit 1.5 Inch

Product Description

The 3M 7000045623 is a coated abrasive disc built for both stock removal and finishing work on metal surfaces. It combines 3M ceramic grain with aluminum oxide in a self-sharpening blend that sustains cut rate longer than straight aluminum oxide alone. The disc mounts via the Roloc attachment system and sits on a heavy polyester backing rated for medium-pressure wet and dry use. A grinding aid embedded in the construction reduces heat buildup, making this disc well-suited for heat-sensitive alloys including stainless steel, nickel alloys, and titanium. Licensed tradespeople and metal fabricators working in production or maintenance environments will find this disc reliable across repeated attachment and removal cycles.

This disc is designed for medium-pressure grinding and finishing applications on metal. The 36-grit ceramic and aluminum oxide blend makes it appropriate for aggressive stock removal where surface heat management is a concern. The 1.5-inch diameter fits compact Roloc-style die grinders and right-angle tools commonly used in confined areas, weld seam work, and edge blending on sheet metal, structural steel, and heat-sensitive alloys. Both wet and dry operation is supported by the water-resistant polyester backing.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for sustained cut rate and improved durability over aluminum oxide alone
• Roloc quick-change attachment system allows fast, secure disc mounting and removal without tools
• Heavy polyester backing resists tearing under medium pressure in both wet and dry conditions
• Grinding aid reduces heat buildup during work on stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive grain to backing under pressure, heat, and moisture exposure

Compatibility

Designed for use with Roloc-style quick-change die grinders and right-angle grinders that accept 1.5-inch diameter quick-change discs.

Installation Notes

Installation and removal are performed by hand using the Roloc twist-lock mechanism — no wrench required. Confirm the grinder is powered off and unplugged before changing discs. Inspect the disc for cracks or damage before each use and do not exceed the tool or disc rated speed. Follow applicable shop safety protocols and wear appropriate PPE including eye and face protection when grinding.
