OVERVIEW

Extreme Performance for Heavy Duty Sanding

The Walter Coolcut XX™ Sanding Disc (48-A-053) represents the pinnacle of abrasive technology for industrial metalworking. Designed for professionals who demand speed and efficiency, this 7-inch disc features a coarse 50 grit rating, making it ideal for aggressive stock removal, weld leveling, and heavy surface preparation. At the core of the Coolcut XX performance is Walter's exclusive Cyclone Technology™, a proprietary blend of premium ceramic grains and high-grade aluminum oxide. This unique formulation allows the disc to cut faster and last significantly longer than conventional sanding discs, reducing downtime for disc changes and increasing overall productivity.

One of the standout features of this disc is its ability to grind cool. Heat generation is a common enemy in metal fabrication, often leading to warping or discoloration (heat tint) on sensitive materials like stainless steel. The Coolcut XX is engineered with active grinding agents that lubricate the cutting surface, dissipating heat effectively. This makes it a versatile choice for a wide range of materials, including carbon steel, stainless steel, and aluminum. Whether you are removing heavy welds in a shipyard or blending surfaces in a fabrication shop, this disc provides the consistency required for high-quality results.

Durability is key in industrial environments, and the Walter 48A053 delivers with a robust vulcanized fiber backing that resists tearing and edge chipping. The 7/8-inch arbor hole ensures compatibility with standard backing pads on 7-inch angle grinders. By maintaining a consistent cut rate throughout its lifespan, the Coolcut XX helps operators maintain rhythm and reduce fatigue, as less pressure is needed to achieve the desired removal rate.

Key Applications

  • Weld Removal: Rapidly grinds down heavy weld seams on structural steel and piping.
  • Surface Leveling: Flattens imperfections and mill scale efficiently.
  • Beveling: Prepares edges for welding with precision and speed.
  • Blending: Smooths out rough surfaces on stainless steel tanks and vessels.

FAQ

The Walter 48A053 Coolcut XX disc has a grit rating of 50, which is considered a coarse-to-medium grit suitable for aggressive stock removal and blending.

Yes, like all resin fiber discs (RFDs), this product must be used with a compatible backing pad (typically a hard or medium density pad for 7-inch grinders) to support the disc and ensure safety.

The Coolcut XX is designed for versatility and performs exceptionally well on steel, stainless steel, aluminum, and other non-ferrous metals.

This disc features a standard 7/8-inch center hole (arbor), which fits the majority of 7-inch angle grinders available on the market.

The maximum safe operating speed for the Walter 48A053 is 8,600 RPM. Always ensure your grinder does not exceed this speed.

Cyclone Technology is Walter's proprietary abrasive blend that combines high-performance ceramic grains with specific geometric shapes to maximize cutting speed and disc longevity.

Yes, the Coolcut XX is engineered to cut cool, making it effective for removing heat tint and discoloration without adding excessive heat back into the material.

These discs are typically sold individually (1 per each), but bulk packaging options may be available depending on the order quantity.
