ABSTRACT:
A rotatably mounted tool for surface working of construction blocks, e.g. concrete or granite blocks, as well as roadways, incorporates a plurality of flat, planar surfaces which are circumferentially spaced apart around the outer, peripheral surface of the generally cylindrical tool drum. A plurality of abrasive mounting shoes are removably secured to the flat drum surfaces, with flat surfaces on the shoes evenly seated in conforming relation to the flat drum surfaces. Abrasive segments are selectively affixed to each mounting shoe in a desired number, size, and spacing to carry out the desired surface working operation, i.e., cutting grooves in road surfaces or smooth finishing concrete blocks. The arrangement and orientation of the abrasive mounting shoes on the tool drum may also be varied in order to achieve full work surface coverage for particular applications.
