3M 7000045627 Coated Abrasive Disc 50 Grit 2 Inch

Product Description

The 3M 7000045627 is a coated abrasive disc engineered for both stock removal and finishing applications in metalworking and fabrication environments. It uses a blend of 3M ceramic and aluminum oxide abrasive grain that self-sharpens during use, maintaining a consistent cut-rate and extending disc life compared to standard aluminum oxide products. A heat-resistant resin bonds the abrasive to a heavy polyester backing, and a grinding aid helps manage heat buildup when working with heat-sensitive alloys. At 50 grit and 2 inches in diameter, this disc is suited to medium-pressure grinding and blending tasks handled by machinists, fabricators, and maintenance professionals.

This disc is designed for use on stainless steel, nickel alloys, titanium, and similar heat-sensitive metals where controlling grinding temperature is critical. The polyester backing supports wet and dry operation, making it adaptable across finishing environments. The Roloc attachment system allows fast, secure mounting and removal from compatible Roloc-style backing pads without tools, reducing downtime during disc changes in production and field settings.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved durability and cut-rate over aluminum oxide alone
• Grinding aid reduces heat buildup, protecting heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heavy water-resistant polyester backing supports medium-pressure use in both wet and dry applications
• Heat-resistant resin bonding provides durability under pressure, heat, and moisture
• Roloc attachment system allows quick, secure disc mounting and removal from compatible backing pads

Compatibility

Designed for use with Roloc-style threaded backing pads compatible with 2-inch coated abrasive discs.

Installation Notes

Installation is performed by threading the disc onto a compatible Roloc backing pad mounted to a die grinder or right-angle tool. Ensure the backing pad and disc diameter match before use. Disconnect or de-energize the tool before attaching or removing the disc. Follow applicable shop safety protocols including eye protection and appropriate RPM ratings for the disc size.
