Scotch-Brite 0645 0 SC-DH Series No-Hole Surface Conditioning Disc, 7 in, Medium Grade, Aluminum Oxide, Maroon

Scotch-Brite™ surface conditioning disc comes in a wide variety of grades and sizes and is an ideal first step for cleaning, blending, deburring and finishing. Durable, non-woven fiber construction conforms well on irregular or contoured surfaces without undercutting or damaging the base material. Our fast cutting Scotch-Brite™ surface conditioning disc is an ideal first step for cleaning, blending, deburring and finishing. The open web material of our discs runs cool and resists loading, for prolonged use. The evenly distributed aluminum oxide abrasives offer a high cut rate for consistent finishing. Our surface conditioning discs use aluminum oxide abrasive, the preferred choice of industry professionals for its fast cut rate and long life.
3M Scotch-Brite non-woven SC-DH hook & loop disc uses aluminum oxide as the abrasive material and has a diameter of 7 in. Since this product is non-woven, grade is generally used to describe the abrasiveness; with the 00645 having a medium grade. 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 3M hook & loop disc can be run at a maximum speed of 6000 RPMs.

Abrasive Type: Non-Woven

Specification parameters description:

Grade:
Grade is a measurement of the size of abrasive particles embedded in coated abrasives. It is a more general measurement of the level of precision, and corresponds roughly to grit. A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work.
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.
Abrasive Material:
Values: A/O Aluminum Oxide AO A/Z Alumina Zirconia AZ S/C Silicon Carbide SC 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. 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 Aluminum Oxide Cerium Oxide Cerium oxide is used for fine polishing and lapping of glass, gemstones, optical mirrors, and lenses. It should be used wet or in slurry form. 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. Nylon 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. Precision Shaped Ceramic Grain Zirconia
