Value Collection 409.87600567 Locking Nut Disc Backing Pad

Product Description

The VALUE COLLECTION 409.87600567 is a hard-density locking nut disc backing pad designed for use with 4.5-inch abrasive discs on angle grinders. At 4.5 inches in diameter, it provides a firm, stable platform that keeps grinding and cutting discs seated securely during operation. The locking nut attachment mechanism allows for fast disc changes without requiring a spanner wrench. Rated for operation up to 20,000 RPM, this backing pad is suited for demanding metalworking, fabrication, and surface preparation tasks. It is typically installed by machinists, welders, metal fabricators, and general maintenance technicians working with angle grinders in shop or field environments.

This backing pad is intended for use in applications requiring a hard-density support surface behind abrasive flap discs, fiber discs, or surface conditioning discs mounted on a 4.5-inch angle grinder. Hard-density construction provides minimal flex, making it appropriate for aggressive stock removal and flat surface grinding rather than contour work. It is a practical replacement or spare component for grinding setups in fabrication shops, maintenance facilities, and construction sites where disc changes occur frequently.

Key Features

• 4.5-inch pad diameter accommodates standard 4.5-inch abrasive discs
• Hard-density construction delivers a rigid backing surface for flat grinding applications
• Locking nut attachment design enables tool-free or minimal-tool disc changes
• Rated up to 20,000 RPM for compatibility with high-speed angle grinders
• Lightweight at 0.5 pounds for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style replacement or spare backing pad for 4.5-inch angle grinders that accept a locking nut disc attachment system.

Installation Notes

Installation and replacement of angle grinder backing pads should be performed by a qualified technician or experienced operator. Always disconnect the grinder from its power source and allow the spindle to come to a complete stop before removing or attaching any backing pad or abrasive disc. Confirm that the maximum RPM rating of the backing pad meets or exceeds the no-load speed of the grinder before use. Follow applicable ANSI B7.1 safety standards for abrasive wheel machinery when mounting and operating grinding accessories.
