15C504 - Walter COOLCUT 5-Inch Resin Fiber Sanding Disc 40 Grit

Aggressive Weld Removal and Surface Prep

For welders, surface preparation is half the battle. The Walter 15C504 Coolcut Sanding Disc (5" diameter, 40 Grit) is built to tackle the toughest grinding and blending tasks in the welding booth. Whether you are leveling a heavy butt weld, removing spatter, or prepping a steel plate for a fresh bead, this resin fiber disc provides the aggression and control needed to get the job done right.

The "Coolcut" name refers to Walter's proprietary bond technology which is formulated to reduce heat buildup during operation. Excessive heat is the enemy of both the abrasive and the base metal; it can cause the disc to break down quickly and can lead to warping or bluing of the steel. By keeping the cutting zone cooler, this disc maintains its cutting aggression for longer, allowing you to grind more metal per disc change. The 40 grit abrasive is particularly effective for rapid stock removal, biting into mild steel with ease.

This disc is designed to be used with a backing pad on an angle grinder. The flexibility of the fiber backing allows the operator to blend contours and reach into slight curves that a rigid grinding wheel might gouge. This makes it a superior tool for finishing work where preserving the profile of the part is important. The 7/8" arbor fits standard 5-inch grinders, making it a universal solution for your tool crib.

Why Welders Choose Coolcut

• Fast Stock Removal: The sharp aluminum oxide grains make quick work of weld seams and heavy mill scale.
• Cooler Grinding: Reduces the chance of heat-affecting the zone you just welded or are about to weld.
• Rugged Construction: The vulcanized fiber backing stands up to the torque and pressure of heavy-handed grinding.

Don't let poor-quality abrasives slow down your fabrication process. Upgrade to the Walter Coolcut 15C504 and experience the difference that a premium, purpose-built sanding disc can make in your daily welding operations.
