OVERVIEW

Premium General Purpose Sanding for Industrial Applications

The Walter 15C454V Coolcut 4-1/2" Sanding Disc (40 Grit) represents a reliable standard in industrial metal finishing. Designed for maintenance, repair, and operations (MRO) environments where cost-efficiency and performance must balance, the Coolcut line delivers consistent results on steel surfaces. This 5-pack configuration is ideal for smaller workshops or specific project requirements where bulk inventory is not necessary, yet professional-grade quality is demanded.

Engineered with a premium aluminum oxide grain, these discs utilize an advanced electrostatic distribution process. This manufacturing technique ensures that the abrasive grains are oriented vertically, maximizing the cutting edges exposed to the workpiece. The result is a more aggressive initial cut and a sustained removal rate throughout the life of the disc. For industrial users, this translates to reduced downtime spent changing discs and faster throughput on sanding tasks ranging from rust removal to light weld leveling.

The structural integrity of the 15C454V is provided by a high-quality fiber backing. This backing is stiff enough to support heavy pressure for stock removal but retains enough flexibility to contour slightly to the workpiece, preventing gouging. The "Coolcut" technology is specifically formulated to dissipate heat generation during the grinding process. By keeping the workpiece cooler, these discs minimize the risk of thermal discoloration or warping, which is critical when working on thinner gauge steel or preparing surfaces for painting and coating.

Key Industrial Benefits:

  • Cost-Effective Performance: Delivers professional removal rates at an economical price point.
  • Heat Management: Specialized active agents in the coating reduce friction and heat buildup.
  • Versatile Application: Excellent for general purpose sanding, surface cleaning, and blending on mild steel.
  • Durable Construction: Fiber backing resists tearing and edge wear under normal grinding pressure.

Equip your facility with Walter Coolcut discs to ensure your team has the right abrasives for efficient steel fabrication and maintenance. Requires a compatible backing pad for use on angle grinders.

FAQ

The Walter Coolcut 15C454V discs are optimized for use on steel. They are excellent for general purpose sanding and light weld removal on mild steel surfaces.

Yes, these are resin fiber discs and must be used with a compatible backing pad on your angle grinder to ensure safety and proper performance.

This specific SKU (15C454V) is a 40 Grit disc, which is considered coarse. It is suitable for rapid material removal rather than fine finishing.

This package contains 5 individual sanding discs.

While you should always check the disc label, standard 4-1/2" fiber discs are typically rated for use on angle grinders with speeds up to approximately 13,300 RPM.

Coolcut refers to the disc's ability to grind with reduced heat generation, preventing the workpiece from overheating, discoloring, or warping.

While it can physically grind aluminum, these aluminum oxide discs are best suited for steel. For aluminum, a disc specifically designed for non-ferrous metals (often with specific lubricants to prevent loading) is recommended.

It is designed for light to medium weld removal. For very heavy stock removal, you might prefer a grinding wheel or a ceramic fiber disc, but for general smoothing, this 40 grit disc works well.
