## Description

Depressed center wheels may also be referred to as raised hub wheels or by their shape designation Type 27, 28 or 29, 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 for cut-off applications when the tool is proper designed with flanges and guards. While large right angle grinders (7" & 9") have been around for many years, small or mini grinders that handle 4", 4-1/2" and 5" wheels have made this machine, and wheel category, the most popular in power tools.

## Features

- Zirconia alumina and silicon carbide for versatility and aggressiveness in a broad range of metalworking applications
- Type 27 depressed center wheels are used for cutting off and portable grinding
- Reinforced design helps provide safety, strength, and straight cuts
- Resin bonds soften under the heat of grinding, releasing dulled abrasive grains
