Walter Coolcut XX 4.5-Inch 36 Grit Resin Fiber Sanding Discs (50-Pack)

Aggressive Grinding for Professional Welders

When you are staring down a long seam weld that needs to disappear, you need an abrasive that bites hard and lasts long. The Walter Coolcut XX 4-1/2" 36 Grit Sanding Disc is the welder's choice for aggressive grinding and blending. This 50-pack (SKU: 15X453B) equips your shop with premium abrasives designed to tackle the most demanding fabrication jobs. The "XX" stands for extreme performance, utilizing Walter's proprietary Cyclone Technology to deliver a cut rate that is simply unmatched by generic fiber discs.

One of the biggest challenges when grinding stainless steel or aluminum is heat management. Excessive heat can lead to discoloration (heat tint) or warping of thin materials. The Coolcut XX is engineered to cut cool, dissipating heat effectively while it works. This makes it an excellent choice for finishing stainless steel tanks, aluminum truck bodies, or custom alloy fabrication where surface integrity is paramount. The 36-grit surface aggressively removes weld beads and slag, leaving a consistent surface profile that is ready for subsequent finishing steps.

Stop wasting time changing out dull discs every few minutes. The Coolcut XX is built for endurance, offering up to six times the stock removal capacity of traditional discs. This durability means you can grind more linear feet of weld per disc, keeping you under the hood and focused on the job rather than running to the supply cabinet. Compatible with standard 4-1/2" angle grinders (using a backing pad), these discs are a versatile staple for any serious metalworker's arsenal.

Why Welders Choose Coolcut XX

• Cool Running: Minimizes heat buildup to protect your base material.
