Walter Coolcut 5-Inch 80 Grit Fiber Sanding Disc (Pack of 5)

Achieve Superior Finishes on Steel Weldments

For professional welders and metal fabricators, surface preparation and finishing are just as critical as the weld itself. The Walter Coolcut 5" Sanding Disc (15C508V) with 80 grit is designed to help you achieve a flawless finish on steel surfaces. Whether you are blending a light weld seam, removing spatter, or preparing a surface for a final coating, this fiber disc provides the control and aggression needed to get the job done right. The 80 grit rating offers a medium-fine finish, perfect for the intermediate stages of sanding where material removal is still necessary but surface quality begins to matter.

The secret to the Coolcut's performance lies in its premium aluminum oxide grain structure. Unlike standard discs that may glaze over or dull quickly, Walter's electrostatic grain distribution ensures that fresh, sharp cutting points are always in contact with the metal. This results in a smooth, consistent cut that requires less operator pressure, reducing fatigue during long grinding sessions. The high-quality fibre backing supports the abrasive grain, preventing edge chipping and ensuring the disc wears evenly throughout its life.

One of the biggest challenges in grinding and sanding is heat buildup, which can ruin the temper of the metal or cause unsightly blueing. Walter's Coolcut technology addresses this by promoting cooler cutting action. This feature allows you to work more confidently on your projects, knowing that the integrity of the base metal is preserved. Compatible with standard 5-inch angle grinders and backing pads, these discs are a versatile addition to any welder's toolkit. From custom fabrication to automotive repair, the Walter 15C508V ensures your work looks as good as it holds.

Welder-Centric Features:

• Cool Cutting: Prevents heat discoloration on finished parts.
• Smooth Blending: Ideal for transitioning weld profiles into base metal.
• Long Life: Durable backing and grain retention mean fewer disc swaps.
