OVERVIEW

Achieve Smooth Finishes with Walter Coolcut Technology

For welders who take pride in the final appearance of their work, the Walter 15C708 Coolcut 7" Sanding Disc is a must-have consumable in the shop. Whether you are prepping a surface for a critical weld or blending out a bead for a seamless finish, this 80 grit resin fiber disc delivers the control and consistency you need. The Coolcut series is built for the everyday hustle of the welding shop, providing a reliable "go-to" abrasive for mild steel applications.

The 80 grit texture is the sweet spot for finishing work. It is aggressive enough to clean up light spatter and strip away corrosion but fine enough to leave a smooth scratch pattern that is easy to paint over or polish further. Using a 7-inch angle grinder with these discs allows you to cover ground quickly, significantly reducing the time spent on post-weld cleanup. The aluminum oxide grain is tough and durable, resisting premature dulling even when working on hot-rolled steel or heavy structural components.

Heat is a major factor when grinding and sanding, and excessive heat can warp thin metals or cause "blueing" that ruins the aesthetic of the piece. Walter's Coolcut technology helps mitigate this by ensuring the disc cuts freely rather than rubbing and generating friction. This results in a cooler workpiece and a longer-lasting disc, saving you money on consumables and time on rework. When paired with a high-quality backing pad, the 15C708 conforms slightly to the metal, allowing for smooth blending of contours and edges.

Upgrade your finishing process with a disc that works as hard as you do. The Walter 15C708 is an economical yet high-performance choice for custom fabricators, repair shops, and mobile welders requiring dependable steel finishing results.

FAQ

The Walter 15C708 Coolcut disc is specifically designed for general purpose sanding on steel.

Yes, resin fiber discs like the 15C708 require a backing pad (typically 7-inch diameter with a 7/8" arbor) to attach to an angle grinder.

This disc is 80 grit, which is suitable for medium finishing, blending, and light cleaning.

The maximum safe operating speed is 8,600 RPM. Always check your grinder's RPM rating before use.

While it can physically sand aluminum, it is optimized for steel. For aluminum, a disc with specific lubricants (like Walter's ALU line) is recommended to prevent loading.

These discs are typically packaged in quantities of 25 per pack.

Coolcut is a general-purpose aluminum oxide disc for steel, while Topcut typically features zirconia grains for faster removal rates on harder metals and stainless steel.

80 grit is generally too fine for heavy stock removal. For removing large amounts of material, start with a 24 or 36 grit disc and use the 80 grit for finishing.
