OVERVIEW

Aggressive Removal for the Toughest Metals

When you are grinding down a weld or blending a surface, you need an abrasive that bites hard and lasts long. The Walter Coolcut XX™ 5" 80 Grit sanding disc is built exactly for that purpose. If you are tired of swapping out discs every few minutes because they stop cutting, this is the upgrade you have been looking for. Thanks to Walter's exclusive Cyclone™ Technology, these discs are designed to self-sharpen and resist loading, meaning they keep eating through metal long after other discs would have ended up in the trash bin. This 50-pack ensures you have plenty of supply for big jobs, keeping you grinding instead of restocking.

The 80-grit abrasive is the sweet spot for welders who need to remove material quickly but also want to start smoothing out the surface for a final finish. It is aggressive enough to take down light welds and spatter but refined enough to leave a consistent scratch pattern that is easy to blend out. Whether you are fabricating with stainless steel, aluminum, or standard carbon steel, the Coolcut XX™ stays cool under pressure. Heat buildup is the enemy of both your abrasive and your metal—especially on stainless—and these discs are formulated to cut cool, preventing discoloration and warping while extending the life of the grain.

Using the Coolcut XX™ feels different; you can feel the disc grabbing the metal rather than just gliding over it. This means you don't have to push as hard, reducing fatigue on your arms and shoulders during long shifts. With a standard 7/8" arbor, these discs fit your 5-inch angle grinder perfectly (requires a backing pad). Stop wasting time with cheap discs that glaze over instantly. Switch to Walter Coolcut XX™ and experience the difference that premium abrasive technology makes in your daily fabrication work. You'll get the job done faster, with a better finish, and use fewer discs in the process.

FAQ

Cyclone Technology is a proprietary blend of abrasive grains and bonding agents developed by Walter. It allows the disc to maintain a high cut rate for a longer period, providing up to 6x more stock removal than standard discs.

You will need a 5-inch backing pad with a standard 5/8"-11 thread (or appropriate thread for your grinder) and a clamping nut compatible with resin fiber discs. Walter offers specific Turbo backing pads for optimal cooling.

Yes, Coolcut XX discs are effective on aluminum. Their cool-cutting properties help prevent the aluminum from melting and clogging (loading) the disc, although using a lubricant or wax can further extend life on soft metals.

80 grit is a medium grade. It removes material slower than 36 or 60 grit but leaves a smoother finish that is easier to polish or paint. It is ideal for blending and light stock removal.

Always check the specific label on the disc, but generally, 5-inch resin fiber discs are rated for angle grinders with speeds up to approximately 12,000-13,000 RPM.

Coolcut XX offers significantly higher productivity. While the initial cost per disc might be higher, the 6x stock removal capacity and 2x speed mean you use far fewer discs and spend less time changing them, lowering total project costs.

Absolutely. They are specifically designed to cut cool, which is critical for stainless steel to avoid heat tinting and warping while maintaining aggressive removal rates.

Resin fiber discs are sensitive to humidity. They should be stored in their original packaging or a climate-controlled environment (ideally 40-50% relative humidity) to prevent curling or brittleness.
