OVERVIEW

Aggressive Grinding Without the Burn

Every welder knows that time is money, and spending half your day changing out worn-out sanding discs is a waste of both. The Walter Coolcut XX 4-1/2" Sanding Disc is built for fabricators who need to hog off metal fast without sacrificing the quality of the metal underneath. This 5-pack of 36 grit discs is your go-to solution for leveling heavy welds, removing spatter, and prepping surfaces for the next pass. If you are tired of discs that glaze over after two minutes or burn your stainless steel, it's time to upgrade to Coolcut XX.

What sets these discs apart is the ceramic grain blend. Unlike standard aluminum oxide pads that dull quickly, ceramic grains fracture as they wear, constantly revealing new, sharp cutting edges. This means the disc cuts just as aggressively at the end of its life as it did at the start. For you, that translates to less pressure needed on the grinder, less fatigue in your arms, and faster job completion. The "XX" in the name stands for extra performance, and you'll feel the difference the moment the disc touches the metal.

Heat is the enemy of a good finish, especially on stainless steel. Walter's Coolcut technology acts like a built-in coolant, keeping the grinding zone temperature down. This prevents that annoying heat tint that you have to polish out later and reduces the risk of warping thinner sheets. The 36 grit is coarse and aggressive—perfect for when you need to remove material in a hurry. Whether you are working on mild steel structural beams or stainless tanks, these discs hold up to the abuse.

This pack contains 5 discs, making it a perfect grab-and-go option for your toolbox or a specific project. They fit standard 4-1/2 inch grinders with a 7/8 inch arbor (don't forget your backing pad!). When you need to grind down a heavy bead or bevel a plate for deep penetration, trust Walter Coolcut XX to get it done right. Stop fighting your grinder and let the abrasive do the work.

FAQ

You will need a standard resin fiber disc backing pad compatible with a 4-1/2" grinder and 7/8" arbor. Walter offers Turbo backing pads that help cool the disc further.

Yes, the Coolcut XX discs can be used on aluminum. However, for dedicated aluminum work, a specialized disc designed to prevent loading (clogging) might offer even better longevity.

Coolcut XX contains a higher performance ceramic grain blend designed for more aggressive removal and longer life compared to the standard Coolcut line.

The maximum safe operating speed is 13,300 RPM. Always ensure your angle grinder does not exceed this rating.

36 grit is considered coarse. It is best used for removing material quickly, such as grinding down welds, rather than for fine finishing.

The disc features active cooling agents in the bonding matrix that reduce friction and heat generation, preventing heat discoloration on the workpiece.

Yes, since these are resin fiber discs with a 7/8" center hole, they are secured to the backing pad using the grinder's locking nut.
