METAL FAB GRINDING AND CUTTING Depressed Center Wheels
Depressed center wheels may also be referred to as raised hub wheels or by their shape designation of “Type”, with Type 27 being the most popular. The depressed center design allows the flange/lock nut to recess within the wheel so that it can be used for various grinding and cutting applications. Depressed center wheels are designed to handle the most severe right angle grinding applications from heavy stock removal to rough blending. More recently, depressed center wheels have been designed to increase the utility of the tool for cut-off applications. While large right angle grinders (7" & 9") have been around for many years, small or mini grinders that handle 4", 4-1/2", 5", and 6" wheels have made this machine, and wheel category, the most popular in power tools. Applications: Grinding, stock removal, edge chamfering, beveling, weld blending, and cutting-off Size Range: 2" – 9" Thickness Range: .040" – 1/4" Grit Range: 24 – 46 grits for stock removal; 60, 80 grits for blending and finishing Abrasive Grain: Ceramic Alumina, Diamond, Zirconia Alumina, Aluminum Oxide, Silicon Carbide Mounting Options: Plain hole (3/8", 5/8" and 7/8") and discard mount (5/8"-11) Shape: Type 27, Type 28, Type 29 Machine Used: RIGHT ANGLE GRINDER The complete product category is described above.

How to Pick the Right Mount
Most wheel sizes come with a plain hole or a discard mount option. While the plain hole has a small, initial cost advantage, the discard mount can provide a labor cost advantage with the quicker wheel change. Mini-Mount Hub
Our unique, patented mini-mount hub used on 4-1/2" and 5" depressed center wheels provides up to 30% more wheel life because the hub covers just a small surface area, providing maximum grinding area exposure and usage.
