ABSTRACT:
A method for deburring and tool for use therein wherein workpiece-engaging portions of a cutter of the tool prevent the cutting of chamfers to hole edges of boreholes. The tool removes burrs from a drilling operation performed on a steering yoke. The yoke includes two boreholes on parallel legs that are drilled in line with one another. The boreholes must be burr-free with little or no chamfer. The cutter is spring-urged or loaded to pivot on a cylindrical shaft to expose cutting edges of the cutter after a predetermined amount of angular movement from a substantially vertical position. The workpiece-engaging portions prevent the cutter from digging in and cutting the chamfers. The cutter rotates into retracted positions within the shaft to allow the cutter to pass through the drilled boreholes so that the cutting edges of the cutter can deburr surfaces of the yoke at both sides of each of the legs.
