Walter Surface Technologies 06B462 Flap Disc 120 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 06B462 is a Type 27 zirconia alumina flap disc engineered for aggressive grinding and finishing on steel and stainless steel. Part of the Enduro-Flex series, this disc measures 4.5 inches in diameter and mounts via a 5/8-11 threaded arbor hole for fast, tool-free attachment to standard angle grinders. The 120 fine grit zirconia alumina abrasive delivers consistent stock removal while producing a finer finish than coarser grit options. The wood fiber backing is trimmable, allowing the operator to expose fresh abrasive as the disc wears, extending usable service life. Maximum operating speed is 13,300 RPM.

This disc is suited for surface grinding, blending, and finishing work on carbon steel and stainless steel in fabrication, maintenance, and welding cleanup applications. The Type 27 flat profile is appropriate for flat surface work and moderate edge access. Fine 120 grit makes it a good choice for pre-paint surface prep, weld blending, and finishing passes where surface condition matters. It is used by metal fabricators, pipefitters, welders, and maintenance technicians working with both ferrous and stainless materials.

Key Features

Compatibility

Designed for use on standard angle grinders with a 5/8-11 threaded spindle accepting 4.5-inch Type 27 flap discs. Rated for material applications including carbon steels and stainless steel.

Installation Notes

Installation is performed by threading the disc directly onto a 5/8-11 grinder spindle - no wrench or backing pad is required. Before mounting, confirm the grinder's rated RPM meets or exceeds the disc's 13,300 RPM maximum operating speed. Always inspect the disc for damage before use and never exceed the maximum RPM rating. Eye protection, gloves, and a face shield are standard PPE for abrasive disc operation per ANSI B11 and tool manufacturer guidelines.
