3M 14270 Retainer Nut Disc Pad Face Plate, 4-1/2 in Dia, Disc Pad Hub Attachment Black

3M™ disc pad face plate backs a same size fiber disc (sold separately) to provide firm support and the force required for grinding applications. It is used in conjunction with a disc pad hub (sold separately), which attaches to the power tool and held into place along with the appropriate disc using either a retainer nut (sold separately). Some face plates have ribbing on the bottom face. Ribbed face plates provide additional force when needed for optimal fracturing of the abrasive mineral. By reducing the area of contact or pressure per square inch (PSI), ribbed face plates increase the grinding pressure of the abrasive with the same amount of operator effort and extend disc life when dulling is a problem.
3M 14270 smooth faceplate is another extremely high quality product from 3M. Most of the products in this category have a maximum RPM. The maximum RPM is designated for both safety and as the upper limit for performance. In this case the maximum RPM is 13,300. When buying power tools or abrasive accessories pay close attention to the diameter of the tool for supported diameters of accessories and abrasives. This product has a 4 1/2 in diameter.
