Type 27 Depressed Center Grinding Wheels – Specifications and Applications

Type 27 Depressed Center Grinding Wheels are high-performance abrasives designed for heavy-duty stock removal, blending, and surface preparation on a wide variety of metals. Known for their versatility and durability, these wheels are a staple in fabrication shops, maintenance operations, and construction sites.

The “Type 27” designation refers to the wheel’s depressed center design, which allows for a flatter grinding angle and better visibility of the work surface. This makes them ideal for aggressive grinding and edge work without gouging or undercutting the base material. Available in various sizes—commonly 4-1/2”, 5”, 6”, 7”, and 9” diameters—these wheels are compatible with right-angle grinders and operate at high RPMs.

Type 27 grinding wheels are constructed using premium aluminum oxide, zirconia alumina, or ceramic abrasive grains, depending on the application. Bonded with high-strength resin, they are engineered for long life and consistent performance. The wheels are available in a range of grits, from coarse (24 grit) for fast material removal to finer grits (60+ grit) for blending and finishing tasks.

These wheels are widely used for grinding weld seams, beveling edges, removing burrs, cleaning up metal surfaces, and smoothing weld beads. Their applications span industries such as metal fabrication, shipbuilding, automotive repair, construction, and pipeline maintenance.

Type 27 depressed center grinding wheels are suitable for use on carbon steel, stainless steel, cast iron, and various alloys. Many variants are also engineered for low vibration and cooler grinding, which extends both wheel life and operator comfort.

For professionals seeking reliable, efficient metal grinding tools, Type 27 grinding wheels provide an ideal balance of power, precision, and safety—delivering excellent results in demanding industrial applications.
