Walter Surface Technologies 07K422 Flap Wheel 80 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 07K422 is an unmounted aluminum oxide flap wheel designed for surface blending, deburring, and finishing on metal workpieces. Measuring 4.5 inches in outside diameter and 2 inches in face width, this coated abrasive wheel features an 80-grit, fine-grade cutting surface built on a cloth backing with interleaved construction for consistent stock removal and surface contact. The 5/8-11 threaded center hole allows direct mounting on compatible angle grinders and finishing tools. Rated to a maximum of 3,800 RPM, it is suited for shop fabricators, pipe fitters, and metal finishing techs who need controlled material removal on curved or contoured surfaces.

This flap wheel is intended for use on aluminum, stainless steel, and carbon steel surfaces where a fine-grade finish is required. The interleaf construction helps maintain wheel shape and extends abrasive life during extended finishing passes. Typical applications include weld blending, edge preparation, and surface conditioning on fabricated components. It is compatible with the Line-Mate 30-A 268 Drum system as listed by the manufacturer.
