Value Collection 01-1033 Fiber Disc 4-1/2 in 120 Grit

Product Description

The VALUE COLLECTION 01-1033 is a resinoid-bonded aluminum oxide fiber disc designed for aggressive material removal and surface blending on metal, welds, and other hard surfaces. At 4-1/2 inches in diameter with a 7/8-inch arbor hole, this disc mounts directly to standard right-angle grinders equipped with a compatible backing pad. The 120-grit aluminum oxide abrasive delivers fine-grade stock removal, making it well suited for finishing passes, light deburring, and surface prep before coating or inspection. The fiber backing provides rigidity and durability under load, maintaining disc shape and abrasive contact throughout the cut.

This disc is a standard choice in fabrication shops, maintenance facilities, and field service environments where technicians need a reliable finishing disc for ferrous and non-ferrous metals. It is commonly used on structural steel, pipe welds, and sheet metal components. The 7/8-inch arbor hole accepts the most common backing pad configurations used with 4-1/2-inch angle grinders, keeping this disc accessible for general-purpose grinding and surface conditioning tasks across residential and commercial job sites.

Key Features

• 120-grit aluminum oxide abrasive for fine-grade surface finishing and light material removal
• Resinoid bond construction for heat resistance and consistent abrasive release under load
• Fiber backing provides rigid support and maintains disc flatness during operation
• 4-1/2-inch diameter fits standard right-angle grinders with compatible backing pads
• 7/8-inch arbor hole matches the most common backing pad hub sizes
• Rated to 13,300 RPM maximum for safe use on standard grinder speed ranges

Compatibility

Designed as an OEM-style replacement or general-use fiber disc for 4-1/2-inch right-angle grinders accepting a 7/8-inch arbor hole backing pad.

Installation Notes

Fiber discs require a rigid or semi-flexible backing pad matched to the disc diameter before mounting on the grinder spindle. Always confirm the grinder's no-load RPM does not exceed the disc's 13,300 RPM maximum rating before operation. Inspect the disc for cracks, tears, or delamination before each use and discard any damaged disc immediately. Eye protection, gloves, and appropriate guards must be in place per applicable ANSI and OSHA abrasive wheel safety standards.
