3M 7010365438 Abrasive Disc 4 Inch 40 Grit Ceramic

Product Description

The 3M 7010365438 is a coated abrasive disc engineered for trade and industrial grinding and finishing applications. It combines 3M ceramic abrasive grain with aluminum oxide in a blended mineral construction that self-sharpens during use, delivering consistent cut rates and extended disc life compared to straight aluminum oxide products. The disc measures 4 inches in diameter and is rated at 40 grit for aggressive stock removal. A heat-resistant resin bond locks the abrasive to a heavy polyester backing, and a grinding aid reduces heat buildup during operation on heat-sensitive alloys.

This disc is suited for metal fabrication, weld blending, and surface preparation in both wet and dry conditions. The polyester backing supports medium-pressure applications and resists water, making it appropriate for stainless steel, nickel alloys, titanium, and similar heat-sensitive materials. The Roloc attachment system allows fast, tool-free disc changes on compatible right-angle grinders and disc holders, supporting efficient production workflows in shop and field environments. It is commonly installed and used by metal fabricators, maintenance mechanics, pipefitters, and HVAC sheet metal technicians.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved durability and cut rate over straight aluminum oxide
• Roloc attachment system provides secure, efficient disc mounting and fast removal without tools
• Heavy water-resistant polyester backing supports medium-pressure wet and dry applications
• Grinding aid reduces heat generation, protecting heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond maintains abrasive adhesion under pressure, heat, and moisture

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc backup pads that accept 4-inch quick-change abrasive discs.

Installation Notes

Mount the disc onto a compatible Roloc backup pad by pressing and rotating until the attachment locks. Ensure the grinder is powered off and unplugged before changing discs. Inspect the disc for damage before each use and do not exceed the maximum RPM rating of the tool or disc. Eye protection, gloves, and appropriate respiratory protection should be worn during grinding operations per applicable safety standards.
