ABSTRACT:
A pot type broach assembly having a plurality of tool holders serially connected to each other. Each tool holder has a plurality of sub-holder slots and a plurality of pilot slots equally spaced about an inner surface. The sub-holder slots and pilot slots are longitudinally aligned. A sub-holder member is attached in each longitudinally aligned sub-holder slot and a pilot member is attached in each longitudinally aligned pilot slot. Each sub-holder member has a pair of longitudinal side mounting faces and at least one broach member is attached to each side mounting face. The pilot member engages the broach members on either side thereof and prohibits lateral displacement of the sub-holders and the attached broach member. The pilot members also guide the part support member to which the part to be machined is attached as it is displaced through the broach assembly.
