Walter Coolcut 7-Inch Resin Fiber Sanding Disc 40 Grit

Heavy-Duty Resin Fiber Disc for Steel Fabrication

For professional welders and fabricators, the Walter 15C704 Coolcut Sanding Disc offers a reliable solution for post-weld cleanup and metal preparation. This 7-inch, 40-grit resin fiber disc is specifically formulated to tackle the demands of working with steel. It provides an aggressive cut necessary for leveling welds and removing heavy scale, while maintaining a smooth operation that reduces operator fatigue during prolonged use.

The Coolcut technology embedded in this disc is designed to promote a cooler grinding zone. In welding applications, controlling heat input during finishing is just as important as during the weld itself to prevent metallurgical changes or heat tinting. The specialized abrasive coating minimizes friction, allowing the disc to cut freely without glazing over. This is essential when performing light weld removal or blending surfaces where a consistent profile is required.

Constructed with a tough fibre backing, this disc provides the rigidity needed for high-pressure grinding applications. It requires a compatible backing pad (sold separately) to function correctly on angle grinders. The 40-grit coarseness is ideal for the initial stages of finishing, effectively stripping away rust, paint, and weld spatter. By combining high removal rates with a durable structure, Walter helps fabricators reduce downtime spent changing worn-out abrasives.

Technical Advantages:

• Optimized for Steel: Tailored for carbon steel applications.
• Cool Grinding: Reduces risk of thermal damage to the workpiece.
• High Durability: Resists edge wear and tearing during aggressive use.
