Tru-maxx Fdt Z120-180-T Fiber Disc 120 Grit 7 Inches

Product Description

The TRU-MAXX FDT Z120-180-T is a 7-inch zirconia alumina fiber disc designed for aggressive material removal and surface finishing on metal, weld seams, and fabricated workpieces. The disc uses a resinoid bond with a fiber backing to deliver consistent cut rates under load. At 120 grit, it falls in the fine grade range, making it well-suited for blending and finishing passes after heavier stock removal. Rated to 8,500 RPM, it is compatible with standard angle grinders and disc grinders equipped with a 7/8-inch arbor hole backing pad. The blue-colored disc provides quick visual identification on the shop floor.

This disc is used in metal fabrication shops, shipyards, structural steel work, and general industrial grinding applications. It is appropriate for finishing mild steel, stainless steel, and other ferrous and non-ferrous metals where a fine surface profile is required. Typical users include fabricators, welders, and maintenance technicians performing deburring, weld blending, and surface prep ahead of coating or inspection. The arbor hole attachment type allows fast disc changes on standard backing pads without tooling.

Key Features

• 7-inch diameter with 7/8-inch arbor hole for standard angle grinder compatibility
• Zirconia alumina abrasive material for longer disc life and consistent cut rate on metal
• 120 grit fine grade for blending, finishing, and pre-coating surface prep
• Resinoid bond with fiber backing resists heat and flexes under pressure
• 8,500 RPM maximum speed rating for use with common 7-inch angle grinders
• Blue disc color allows quick visual identification by grit grade

Compatibility

Designed for use with standard 7-inch angle grinders and disc grinders using a 7/8-inch arbor hole backing pad. Suitable for coated abrasive applications on ferrous and non-ferrous metal surfaces.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive disc safety procedures. Confirm the grinder is unplugged or power is isolated before mounting or removing the disc. Verify the tool's rated RPM meets or exceeds the disc's 8,500 RPM maximum before use — never exceed the disc speed rating. Inspect the disc for cracks or damage before each use and follow ANSI B7.1 safety guidelines for abrasive wheel use.
