Scotch-Brite 00648 SC-DH Series No-Hole Surface Conditioning Disc, 7 in, Super Fine Grade, Silicon Carbide, Gray

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 silicon carbide 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 00648 having a super fine 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.
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.
System..Abrasive Material:
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.
System..Abrasive Type:
Non-Woven Non-woven abrasives are formed by dispersing abrasive grains throughout a synthetic fiber mesh. They tend to be less aggressive than coated abrasives and are commonly used for surface conditioning and finishing. When a density rating is provided, this describes the number of fibers that have been compressed into the mesh. Non-woven abrasives are always waterproof.
