Walter Surface Technologies 07M442 Flap Wheel 4.5x4 in Coarse

Product Description

The WALTER SURFACE TECHNOLOGIES 07M442 is a nonwoven aluminum oxide unmounted flap wheel designed for surface conditioning on metal workpieces. Measuring 4.5 inches in outside diameter and 4 inches in width, this wheel features a 5/8-11 threaded center hole for secure mounting. It carries a coarse grade abrasive rating and is rated for a maximum of 3,800 RPM. The nonwoven construction delivers consistent scratch patterns and conforms to irregular or contoured surfaces without loading. Metalworking fabricators and finishing technicians install this wheel for aggressive material removal and surface prep on a range of ferrous and non-ferrous metals.

The 07M442 is suited for surface conditioning applications on aluminum, brass, copper, stainless steel, and other alloys. It is designed for use on fabrication shop equipment where a drum-style surface conditioning setup is required. Typical applications include deburring, blending, and light stock removal on flat or slightly curved workpieces. This wheel is well matched for production-level metalworking environments where consistent finish quality across multiple passes is required.

Key Features

• Nonwoven aluminum oxide construction conforms to contoured surfaces without loading
• Coarse grade abrasive for aggressive deburring and surface blending
• 5/8-11 threaded center hole for positive, secure drum mounting
• 3,800 RPM maximum rating for safe operation on compatible equipment
• Compatible material applications include aluminum, brass, copper, stainless steel, and other alloys
• No interleaf design provides open structure and extended wheel life in metalworking applications

Compatibility

Installation Notes

This wheel is installed by metalworking technicians onto compatible drum-style surface conditioning equipment. Before mounting or replacing the wheel, power down and disconnect the equipment from its power source. Verify that the spindle thread size matches the 5/8-11 center hole before installation, and confirm operating speed does not exceed the 3,800 RPM maximum rating. Never exceed the rated RPM, and inspect the wheel for damage before each use.
