Walter Surface Technologies 06U456 Flap Disc 60 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 06U456 is a Type 27 zirconia alumina flap disc engineered for aggressive material removal on aluminum and other non-ferrous surfaces. Part of the Enduro-Flex Alu series, this 4.5-inch disc runs at a maximum of 13,300 RPM and features a polyester backing for added durability and flex during use. The 60-grit abrasive delivers a balance of cut rate and surface finish suitable for weld blending, edge work, and surface preparation. It mounts via a 5/8-11 arbor hole for direct compatibility with standard angle grinders. Metal fabricators, welders, and general contractors are the primary users of this disc type.

This flap disc is designed for use with angle grinders in fabrication shops, job sites, and maintenance environments where aluminum grinding and surface conditioning are required. The Type 27 flat profile suits flat surface work and moderate edge applications. The zirconia alumina grain self-sharpens under pressure, extending usable disc life compared to standard aluminum oxide abrasives. Its orange polyester-backed construction provides consistent performance across the full service life of the disc.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always verify the grinder spindle speed does not exceed the 13,300 RPM disc rating before mounting. Ensure the grinder is unplugged or its power source is isolated before changing discs. Use the appropriate guard and personal protective equipment including eye and face protection when operating angle grinders with flap discs.
