Walter Surface Technologies 07M423 Flap Wheel 4.5x2 in Medium

Product Description

The WALTER SURFACE TECHNOLOGIES 07M423 is a nonwoven aluminum oxide unmounted flap wheel designed for surface conditioning and finishing on metal substrates. Measuring 4.5 inches in outside diameter and 2 inches wide, this wheel mounts via a 5/8-11 threaded hole and runs at a maximum of 3,800 RPM. Medium grade aluminum oxide construction delivers consistent scratch patterns and controlled material removal without aggressive cutting. Fabricators, welders, and metal finishing technicians reach for this wheel when blending welds, removing light scale, or preparing surfaces for coating or inspection on non-ferrous and ferrous metals alike.

This flap wheel is suited for surface conditioning applications on aluminum, brass, copper, stainless steel, and other alloys. The nonwoven construction conforms to contours and produces a uniform finish across irregular or curved surfaces. It is compatible with line-type drum finishing setups and is packaged individually, making it a practical replacement unit for shops running continuous finishing operations.

Key Features

• Nonwoven aluminum oxide construction for consistent, controlled surface conditioning
• Medium grade abrasive suitable for blending, deburring, and pre-coat surface prep
• 4.5-inch outside diameter with 2-inch face width for solid coverage on flat and curved surfaces
• 5/8-11 threaded center hole for direct mounting on compatible drums and arbors
• Rated to 3,800 RPM maximum for safe use at standard finishing speeds
• Compatible with aluminum, brass, copper, stainless steel, and other alloys

Compatibility

Compatible with the Line-Mate 30-A 268 Drum and Surface Conditioning Drum as stated by the manufacturer. The 5/8-11 threaded hole fits standard arbors and drum mandrels using that thread specification.

Installation Notes

Installation is typically performed by fabricators, metal finishers, or maintenance technicians familiar with bench or portable finishing equipment. Before mounting or replacing the flap wheel, power down and lockout/tagout the machine per OSHA lockout procedures. Verify that the arbor or drum thread matches the 5/8-11 specification and that the spindle speed does not exceed the 3,800 RPM maximum rating of this wheel. Inspect the wheel for damage before use and do not force-mount or over-tighten beyond hand-snug with tool assist.
