Walter Surface Technologies 15R462 Flap Disc 120 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15R462 is a Type 27 zirconia alumina flap disc engineered for grinding and blending on steel and stainless steel surfaces. Running at a maximum of 13,300 RPM, this 4.5-inch disc features a 7/8-inch arbor hole and a fine 120-grit abrasive coating bonded to a wood fiber backing. The trimmable design allows the operator to expose fresh abrasive as the disc wears, extending usable life without swapping discs mid-job. It belongs to the Enduro-Flex series and is suited for fabricators, welders, and metal finishing tradespeople who need consistent, controlled stock removal on ferrous and non-ferrous alloys.

This disc is intended for use on angle grinders in fabrication shops, field welding operations, and maintenance environments where surface preparation on steel or stainless steel is required. The Type 27 flat profile provides a low grinding angle, making it well suited for flat and contoured surface work. Fine 120-grit abrasive makes it appropriate for blending weld seams, removing light mill scale, and finishing passes rather than aggressive stock removal. The orange disc color aligns with the Enduro-Flex series for easy identification on the job site.

Installation Notes

Mount on a compatible angle grinder rated for 4.5-inch accessories and confirm the tool's free-speed RPM does not exceed the 13,300 RPM disc rating before operation. Disconnect the grinder from its power source before installing or removing the disc. Always use the appropriate guard and personal protective equipment including eye and face protection when operating abrasive discs. Follow ANSI B7.1 and applicable workplace safety regulations for abrasive wheel use.
