Tru-maxx Fdt A100-180 Fiber Disc 100 Grit 7 in Aluminum Oxide

Product Description

The TRU-MAXX FDT A100-180 is a 7-inch resinoid-bonded fiber disc designed for aggressive material removal and surface finishing on metal, welds, and similar substrates. The disc uses aluminum oxide abrasive at 100 grit, placing it in the fine grade range for controlled stock removal without excessive surface scarring. It mounts via a standard 7/8-inch arbor hole and is rated to 8,500 RPM, making it compatible with most 7-inch right-angle grinders used in fabrication, maintenance, and industrial finishing work. The fiber backing provides durability under pressure and heat generated during grinding operations.

This disc is suited for use in metal fabrication shops, maintenance facilities, and field service environments where consistent surface conditioning is required. Typical applications include weld blending, rust removal, and prep work before coating or painting on ferrous and non-ferrous metals. The maroon-colored disc helps operators distinguish grit level at a glance on busy shop floors. It is installed and used by machinists, pipefitters, fabricators, maintenance mechanics, and general industrial tradespeople.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety practices. Always confirm the grinder's no-load RPM rating does not exceed the disc's 8,500 RPM maximum before mounting. Power down and unplug or lock out the grinder before attaching or removing the disc. Inspect the disc for cracks, chips, or damage before each use and never use a damaged disc.
