A line of small, thin-profile Type 1 cotton fiber abrasive wheels for deburring slots, gears, stampings and castings, and cleaning pipe threads is available from Rex-Cut Products Inc.
Type 1 Abrasive Wheels feature multiple layers of cotton-fiber that are impregnated with aluminum oxide or silicon carbide abrasives and laminated, pressed, and bonded into dense wheels. Continuously exposing fresh abrasives as they work, these long-life wheels come in 1" to 4" dia. sizes from 1⁄32" to ½" thick for reaching into slots and crevices that are too narrow for conventional unitized wheels.
Suitable for aluminum, steel, stainless steel, titanium Inconel, and other exotics, Rex-Cut Type 1 Abrasive Wheels are capable of lasting up to 10 times longer than unitized wheels, claims the firm. Available in coarse, medium, fine, and very-fine grits with soft or hard bonds, applications include aircraft production, metal fabrication, and pipe thread maintenance.

- aluminum oxide
Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.
