Walter Surface Technologies 15X453 Fiber Disc 36 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15X453 is a ceramic-grain fiber disc engineered for heavy stock removal on metal surfaces. Part of the Cool Cut XX series, it runs a 36 grit very coarse rating that aggressively cuts through weld seams, scale, and surface defects without loading. The resinoid bond holds ceramic abrasive grains in place under high-heat conditions, and the fiber backing gives the disc the stiffness needed for consistent contact across flat and slightly contoured workpieces. Rated to 13,300 RPM, it is designed for use on standard 4-1/2 inch angle grinders and depressed-center grinders used in fabrication and maintenance work.

This disc is suited for metal fabrication shops, structural steel work, shipbuilding, and heavy industrial maintenance. It is a go-to choice when operators need fast material removal on carbon steel, stainless, and cast iron before finishing operations. The arbor hole mount allows quick swap on grinders with a standard 7/8 inch arbor configuration. The Cool Cut XX series orange fiber disc is intended for professional tradespeople working in environments where disc durability and consistent cut rate matter across extended use cycles.

Key Features

• Ceramic abrasive grain for aggressive, self-sharpening cut on metal
• 36 grit very coarse grade for rapid stock removal and weld dressing
• Resinoid bond resists heat buildup during sustained grinding
• Fiber backing provides rigidity and consistent disc contact
• Rated to 13,300 RPM for compatibility with standard angle grinders
• Arbor hole attachment for fast mounting on 7/8 inch arbor grinders

Compatibility

Designed for use on 4-1/2 inch angle grinders fitted with a 7/8 inch arbor. Part of the Walter Cool Cut XX series of coated abrasive fiber discs.

Installation Notes

Fiber discs must be mounted with a compatible backing pad rated for the disc diameter and RPM. Always confirm the grinder guard is in place and the tool RPM rating meets or exceeds the disc maximum RPM before operation. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or deformation. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
