Abstract: A holder and saw guide device for an elongated tube or rod type workpiece includes V-shaped support areas accommodating various size workpieces in a first cavity. A gripping member extends into the first cavity for positioning in a gripping relation with the workpiece along a first concave surface of the gripping member. A second concave surface disposed on an opposite face of the gripping member presents a reversely-curved configuration. The second concave surface cooperates with a stem which is adapted for selective axial shifting movement. The gripping member is biased toward an open position facilitating installation and removal of the workpiece. A pair of parallel walls are disposed in generally normal relation to the longitudinal axis of the workpiece. These walls advantageously include hardened wear plates which line a guide structure for a cutting blade. A mounting member facilitates securing the device to an associated surface.

Abstract: A deburring tool for reaming inner and outer diameter end portions of tube and pipe-like workpieces includes a cast housing having an integrally formed conical support member therein. The conical support member has a base portion disposed adjacent one end of the housing and an apex area spaced toward the other end of the housing. Radially disposed apertures having a predetermined width dimension divide the conical support member into a plurality of wedge portions. A blade assembly is comprised of a plurality of separate blades which are fixedly secured to each other in a pattern identical to the pattern of apertures in the support member. The blades have a thickness dimension which is greater than the width dimension of the apertures in order that the blade assembly will be retained in the conical support member by a press-fit relationship established between the blades and apertures.
