Depressed-Center Grinding Wheels
Available1 product
Depressed-center grinding wheels install on angle grinders for offhand grinding and stock removal, beveling, and smoothing weld lines. Sometimes called raised hub grinding wheels, they're designed to be used at a 30° angle to the workpiece and last long than flap discs and fiber discs.
Primary Material Application
High-Performance Grinding Wheels for Carbon & Stainless Steel
High-performance grinding wheels optimized for use on carbon and stainless steel are made of zirconia alumina. Zirconia alumina is more durable than aluminum oxide and self-sharpens to maintain a sharp cutting edge.
Type 27 Wheel
Type 27 (sometimes called type 42) has a raised hub to allow the wheel to contact the workpiece flat or up to a 45° angle. Sometimes called depressed center or raised hub wheels, they're reinforced with fiberglass to provide extra stability when working on an edge.
