Dewalt XP Type 29 flap disc uses ceramic as the abrasive material and has a diameter of 4 1/2 in. Dewalt incorporates this ceramic material into the flap disc forming a grit of 40. 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 flap disc 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 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 Oxide/Ceramic PSG 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. Ceramic Alumina Ceramic/Alumina Zirconia Ceramic Aluminum Oxide Ceramic Precision-Shaped Grain 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. S/C Silicon Carbide SC Silicon Carbide Silicon carbide is a manufactured material that is extremely hard but brittle. It is commonly used for fast cutting under light pressure, particularly on cast iron, nonferrous metals, and materials such as glass and plastic. Zirconia Zirconium
Grit:
Grit is a measurement of the size of abrasive particles embedded in coated abrasives. The most common standards for grit size are the United States CAMI (Coated Abrasive Manufacturers Institute) and the European FEPA (Federation of European Producers of Abrasives). A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work. Grit is generally a unitless measure but is sometimes measured in microns.
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.
