3M sanding disc backing pad has a diameter of 5 in. The hook & loop attachment allows for easy mounting to the tool or pad. To aid in dust control, this product is designed to work with vacuum systems and comes with 44 holes built into the Sanding Disc Backing Pad. The sanding disc backing pad has a width of 1/2 in. 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 sanding disc backing pad can be run at a maximum speed of 12000 RPMs.
Specification parameters description:
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.
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.
Density Grade:
Density can be rated as soft to extra hard, with softer densities providing better conformability and hard densities suited to heavy-duty deburring, grinding, and polishing.
