Pack of 2 replacement 100mm x 152mm x 152mm hook & loop backing pads for the R7680 & R7681 Delta Orbital Sanders. These low profile backing pads feature 31 holes, with air channels directed towards to the centre of the pad, for effective dust extraction when used with a suitable abrasive such as Rutlands® Net Abrasives and a connected dust extractor. Pads are medium density, providing a small amount of flex appropriate for general use. Regular backing pad replacement is essential for the longevity of the sander, as worn pads can unbalance the sander causing vibration and motor damage. ©
