Metabo 623479000 Unmounted Flap Wheel 80 Grit 4 Inch

Product Description

The METABO 623479000 is a coated abrasive unmounted flap wheel designed for surface conditioning and material removal on metal workpieces. Built with zirconia alumina abrasive, this medium-grade wheel delivers consistent cut and finish across a range of metal applications. The 4-inch diameter by 4-inch width gives it a broad contact face suited to contouring, blending, and deburring on curved or irregular surfaces. Rated to 5800 RPM, it fits standard bench-mounted or arbor-driven spindle setups. The center hole with slots accommodates secure mounting on compatible mandrels. This wheel is used by fabricators, machinists, and maintenance techs who need a reliable, long-cutting abrasive for ferrous and non-ferrous metal work.

This flap wheel is intended for metalworking applications in fabrication shops, maintenance facilities, and production environments. It excels at blending weld seams, removing scale, and finishing contoured surfaces where flat abrasive discs cannot conform. The 80-grit medium grade makes it suitable for intermediate stock removal and surface prep before finer finishing stages. No interleaf construction is used, keeping the abrasive face fully exposed for aggressive contact with the workpiece.

Key Features

• Zirconia alumina abrasive for aggressive cut and durability on metal surfaces
• 80 grit medium grade balances stock removal with surface finish quality
• 4-inch diameter by 4-inch width provides a wide contact area for contouring and blending
• Maximum operating speed of 5800 RPM
• Center hole with slots for secure mandrel mounting
• No interleaf design keeps abrasive fully exposed for direct workpiece contact

Compatibility

Designed for use on metal surfaces as an unmounted flap wheel mounted to a compatible arbor or spindle mandrel rated for the 4-inch bore with slotted center hole configuration.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Always verify the spindle speed does not exceed the 5800 RPM maximum rating before mounting. Inspect the wheel for damage before each use and ensure the mandrel and mounting hardware are rated for the wheel diameter and weight. Never exceed the rated RPM and always use appropriate eye and face protection during operation.
