15C454V - Walter Coolcut 4.5-Inch 40 Grit Resin Fiber Sanding Discs (5-Pack)

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.
