DEWALT DW8807 Zirconia Grinding Wheel - Type 27 (Depressed Center) - 4 1/2" Diameter - 1/8" Thickness

Dewalt XP grinding wheel uses zirconia as the abrasive material and has a diameter of 4 1/2 in. In addition to the other aspects of these parts, another important component of these is the thickness. This Dewalt part is 1/8 in thick. All abrasive products that rotate or spin, such as the ones in this category, have a maximum speed at which you can run them. This Dewalt grinding wheel can be run at a maximum speed of 13300 RPMs.
Specification parameters description:
Abrasive Material:
Values: A/O Aluminum Oxide AO A/Z Alumina Zirconia AZ S/C Silicon Carbide SC Alumina Zirconia Alumina zirconia is very dense and can be used under high temperatures for heavy-duty stock removal, wood planing, and grinding of fiberglass and plastics. The abrasive grain is designed to fracture during use so that it maintains sharpness. Aluminum Oxide Aluminum oxide is an artificial abrasive suited for general purpose stock removal and finishing. It is the mostly commonly used abrasive and can be used for most steels and ferrous alloys. Aluminum oxide is slightly softer but tougher than silicon carbide. Aluminum Silicate Aluminum silicate is a synthetic abrasive used mainly for cleaning steel, nonferrous materials, and stonework. CBN Cubic boron nitride (CBN) is a synthetic material used in superabrasive products. It is similar in hardness to diamond and is very cool cutting. CBN is used for grinding high speed steel (HSS), hardened cast iron, and stainless steel. Ceramic Ceramic is used for aggressive cutting and grinding of stainless steel, titanium, and metal alloys. The abrasive grain is designed to fracture during use so that it maintains sharpness. Diamond Diamond can be either natural or manufactured and is one of the hardest abrasive materials. It is commonly used for grinding and polishing stone and very hard steels, and for sharpening other cutting tools.

Maximum RPM:
The maximum rotations per minute (RPM) a product is designed to be used at should be respected for the sake of safety and use life. Maximum RPM is provided for all product listings where applicable and is often printed on the item in the case of discs and wheels. Operating a wheel above its maximum recommended speed can cause a wheel to crack or even shatter.
