Walter COOLCUT XX 4.5 Inch Ceramic Resin Fiber Disc Grit 36

Get the Job Done Faster with COOLCUT XX™

If you are tired of swapping out sanding discs every ten minutes while grinding down heavy welds, the Walter COOLCUT XX™ is the upgrade you need. This isn't your average hardware store sandpaper; it's a beast built for the daily grind. The 48H396 is a 4-1/2 inch disc with a coarse 36 grit, designed specifically to hog off metal fast. Whether you are leveling a messy MIG weld on structural steel or smoothing out a TIG root on stainless, this disc bites hard and doesn't let go. The secret is in the ceramic grain—it's engineered to stay sharp. Instead of rounding over and just rubbing the metal (which creates heat and turns your workpiece blue), these grains fracture to create new sharp edges as you work.

For welders, time is money, and the COOLCUT XX™ saves you both. Because it cuts so aggressively, you don't have to lean on the grinder as hard, saving your arms and back from fatigue during long shifts. It runs cooler than standard discs, which means you are less likely to ruin a piece of stainless with heat tints right at the finish line. It fits your standard 4-1/2" angle grinder with a 7/8" arbor (just make sure you have a backing pad).

This disc is all about throughput. You get more grinding done per disc, meaning fewer trips to the tool crib and more time making sparks. It works on everything from mild steel to aluminum. If you have heavy stock removal to do and want to go home on time, throw a COOLCUT XX™ on your grinder and watch the metal disappear.
