Specification parameters description:
Number of Vacuum Holes:
Some sanding discs have a pattern or 5, 6, or 8 vacuum holes, or even a pattern of many smaller holes, to allow a power tool to minimize dust created during operation. Reduced dust can keep the abrasive grains on a disc from clogging and thus can improve disc life. Note that sanding disc backing pads are also sold with the standard hole configurations and should match the sanding disc if they are used.
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.
