Walter Coolcut 4.5 Inch Resin Fibre Disc Grit 36

Aggressive Weld Removal and Finishing

For professional welders, time is money, and the Walter Coolcut 4-1/2" Sanding Disc (Grit 36) is built to save both. This resin fibre disc is specifically tailored for the aggressive removal of weld seams, spatter, and heavy stock on steel surfaces. The 36 grit abrasive offers the bite needed to level welds quickly, transitioning a rough, as-welded joint into a smooth surface ready for the next step in fabrication. Its compatibility with standard 4-1/2 inch angle grinders makes it a staple consumable for any welding rig or fabrication shop.

Engineered for the Fabrication Shop

Fabricators know that not all abrasives are created equal. The Coolcut disc features a tough, high-quality fibre backing that provides the stiffness required for bearing down on hard welds without the disc collapsing or shredding. This structural integrity allows welders to apply the necessary pressure to grind effectively while maintaining control over the tool. The electrostatic grain alignment ensures that the abrasive stays sharp longer, providing a consistent cut rate from the first spark to the last, preventing the frustration of discs that glaze over prematurely.

Preventing Heat Defects

One of the biggest challenges in finishing welds is managing heat input. Overheating the base metal during grinding can lead to blueing, heat-affected zones, or even micro-cracking. Walter's Coolcut technology is designed to mitigate this risk by promoting a cooler cutting action. This is essential when preparing surfaces for critical coatings or when the aesthetic appearance of the bare metal is a priority. By reducing heat buildup, you ensure a cleaner, professional-looking finish that requires less rework.

Reliable Performance in Every Pack

Sold in packs of 25, these discs ensure you have the inventory needed to keep the sparks flying and production moving. Whether you are working on structural steel, repairing heavy equipment, or performing custom fabrication, the Walter Coolcut disc adapts to the task. Its ability to perform general-purpose sanding, light weld removal, and surface cleaning with a single product type simplifies your inventory and ensures you always have the right tool for the job. Trust in Walter's reputation for quality to deliver a sanding disc that works as hard as you do.
