Walter Surface Technologies 06F454 Flap Disc 40 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 06F454 is a Type 27 zirconia alumina flap disc designed for aggressive material removal on angle grinders. Built with a coarse 40-grit abrasive bonded to a plastic backing, this disc delivers consistent cut rates across aluminum, stainless steel, and other non-ferrous metals. The zirconia alumina grain self-sharpens during use, extending disc life compared to standard aluminum oxide. Rated to 13,300 RPM, it fits standard 5/8-11 arbor spindles and carries a trimmable design that allows the operator to expose fresh abrasive as the flap wears. Fabricators, welders, and metal finishing techs will find it suited to weld blending, edge chamfering, and surface prep work.

This flap disc is intended for use on 4.5-inch angle grinders in metal fabrication, structural steel, and sheet metal applications. Its material compatibility includes aluminum, non-ferrous metals, and stainless steel, making it a practical choice for shops that work across multiple substrate types without swapping discs. The Type 27 flat profile is well-suited to flat surface grinding and blending rather than edge work, and the plastic backing keeps weight low while resisting heat buildup during extended passes.

Key Features

• 40-grit coarse zirconia alumina abrasive for aggressive material removal
• Type 27 flat profile optimized for flat surface grinding and blending
• Plastic backing reduces weight and resists heat during use
• Trimmable design exposes fresh abrasive as the disc wears
• Rated to 13,300 RPM for use on standard angle grinders
• Compatible with aluminum, stainless steel, and non-ferrous metals

Compatibility

Designed for use with angle grinders equipped with a 5/8-11 arbor spindle. Suitable for grinding and blending on aluminum, non-ferrous metals, and stainless steel surfaces.

Installation Notes

Mounting and disc changes should be performed by qualified operators following the angle grinder manufacturer's safety guidelines. Always confirm the grinder's rated RPM meets or exceeds the disc's 13,300 RPM maximum before mounting. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or abrasive separation. Use appropriate PPE including eye protection and gloves when operating grinding equipment.
