Tru-maxx Fdt A036-100 Fiber Disc 36 Grit 4 Inch

Product Description

The TRU-MAXX FDT A036-100 is a 4-inch coated fiber disc designed for aggressive material removal on metal, welds, and rough surfaces. It uses aluminum oxide grain bonded with a resinoid bond to a fiber backing, delivering consistent stock removal at grit 36 -- a very coarse grade suited for heavy grinding and surface preparation tasks. The disc mounts via a standard arbor hole and is rated to 15,300 RPM, making it compatible with most angle grinders used in fabrication and maintenance work. Metalworkers, pipefitters, and general trade professionals reach for this disc when fast, controlled cutting action is the priority.

This fiber disc is a standard choice for grinding and blending operations on ferrous metals, structural steel, and weld seams in both shop and field environments. At 4 inches in diameter with a 5/8-inch center hole, it fits compact angle grinders commonly used in tight-access areas. The very coarse 36-grit cut rate makes it most effective in initial-pass stock removal before stepping down to finer abrasives for finishing. It is sold individually with a minimum order quantity of 25 units.

Installation Notes

Installation and disc changes should be performed only with the grinder unplugged or the battery removed and the tool at a full stop. Inspect the disc for cracks, tears, or delamination before mounting -- do not use a damaged disc. Ensure the grinder guard is properly positioned before operation, and confirm the tool RPM rating meets or exceeds the disc maximum of 15,300 RPM. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
