Abstract
Reversible thread cutting tool holders having a holder body, a plate and a clamp for securing and orienting a cutting insert on opposite sides of the holder body. In one embodiment, the plate is a flat member being reversibly orientated on a top surface of the holder body and having a cut-out portion to receive part of the cutting tool. The clamp is attached to either side of the holder body and cooperates with the cut-out portion to secure the cutting insert. In a second embodiment, the holder body includes a cut-out portion to receive the cutting insert and the plate is an angle plate. The angle plate and clamp are selectively positioned on opposite surfaces of the holder body adjacent the cut-out portion to orient the cutting insert for opposite thread cuts.
