ABSTRACT OF THE DISCLOSURE A broaching tool is described for broaching planar surfaces. The tool includes an elongated flat tool body having a plurality of spaced ribs disposed generally transverse to the longitudinal body axis. A plurality of cylindrical cutter discs are mounted along each rib, with each disc being positioned with its flat face disposed 1-15° of coincidence with the longitudinal axis of the body. Each disc has a cylindrical end face providing a cutting edge disposed about the periphery of the end face. The discs along each rib are staggered laterally with respect to the discs of the next adjacent rib, with each disc projecting beyond the outer face of the rib and being rotatably indexable about its longitudinal axis to bring successive cutting portions into cutting position.
