ABSTRACT:
An apparatus for grinding cutouts in the ends of pipes has a pair of pulleys which carry a grinding belt. One of the pulleys is a driving pulley for the belt and the other pulley is a shaping pulley which cooperates with the grinding belt to form the cutouts. A pipe clamp is located near, and is movable towards and away from, the shaping pulley. The shaping pulley is interchangeable in order to permit changes in cutout size. To this end, a stub projects from either end of the shaping pulley and supports a ball bearing. The ball bearings are receivable in carriers having U-shaped openings so that the shaping pulley can be installed and removed by pushing the bearings into the openings and pulling the bearings out of the openings.
