Pferd 69480 Disc Backing Pad 4.5 in 5/8-11 Thread

Product Description

The PFERD 69480 is a flexible disc backing pad designed to support fiber discs during grinding, blending, and surface preparation work. Measuring 4.5 inches in diameter and featuring a 5/8-11 thread mount, this backing pad attaches directly to angle grinders and right-angle grinders commonly used in fabrication, maintenance, and metalworking applications. The flexible density construction allows the disc to conform slightly to irregular or curved surfaces, improving contact and cutting consistency. Rated to a maximum of 13,300 RPM, it is built to handle the rotational demands of standard angle grinder operation. Installation and disc changes are straightforward, making it a reliable shop accessory for daily production use.

This backing pad is intended for use with fiber discs in industrial and trade settings, including structural steel fabrication, weld blending, pipe work, and general metal surface conditioning. It is suited for both shop bench work and field service where a 4.5-inch angle grinder is the primary tool. The 5/8-11 thread is the standard spindle thread found on most North American angle grinders in this size class, making this pad broadly applicable across common tool inventories.

Key Features

• 4.5-inch diameter provides full backing coverage for standard 4.5-inch fiber discs
• 5/8-11 thread mounts directly to standard angle grinder spindles
• Flexible density construction allows conformance to curved or uneven workpiece surfaces
• 13,300 RPM maximum rating compatible with typical angle grinder operating speeds
• Lightweight at 0.29 pounds, minimizing added tool weight during extended use

Compatibility

Designed for use with fiber discs on angle grinders equipped with a 5/8-11 spindle thread. Compatible with 4.5-inch fiber discs as noted in manufacturer specifications.

Installation Notes

Installation is performed by threading the backing pad onto the angle grinder spindle and securing it hand-tight before mounting the fiber disc. Always power down and disconnect the grinder from its power source before changing backing pads or discs. Verify that the tool RPM rating does not exceed the 13,300 RPM maximum of this pad. Follow applicable ANSI B11 and tool manufacturer guidelines for abrasive accessory mounting and guard use.
