摘要： A broaching insert, such as a slotter or semifinisher, which cuts through a workpiece is configured such that side cutting edges of the broaching insert contact the workpiece simultaneously. If the broaching insert is a slotter, a center portion of the cutting edge which interconnects the side cutting edge makes contact with the workpiece ahead of the side cutting edges. If the insert is a semi-finisher, the side cutting edges are scalloped so as to reduce shock upon engagement with the workpiece. The broaching insert is ideally suited to the cutting of workpieces oriented obliquely relative to the direction of cutting. In order to minimize snap-back of the broaching insert as it exits the workpiece, the broaching insert is sequentially passed through back-up disks of gradually diminishing hardness, whereby the compressive loading on the insert is relieved gradually.

摘要： A broaching tool includes a holder and a plurality of broaching inserts mounted therein. Spacers are situated between successive pairs of inserts and are formed of a tougher material than the inserts. Each spacer includes a reinforcing web which abuts against a rear surface of its respective leading insert. The reinforcing web extends higher than a lower level of the cutting edge of that respective leading insert, so as to reinforce that insert. The web terminates short of its respective trailing insert, whereby a space is formed between the reinforcing web and the trailing insert for receiving chips formed by the latter.

摘要： The machine tool parts and method of making same includes providing cooperating attachment means between the shank and the tool bit head assembly, wherein a predetermined portion of the attachment means on the shank is located a first predetermined distance from a fixed reference on the shank and the cutting edge of the tool bit head assembly is located a fixed predetermined distance from a portion of the attachment means on the tool bit head assembly, corresponding to the predetermined portion of the shank attachment means, with the additive sum of the first and fixed predetermined distances defining a predetermined cutting height of the cutting edge. Preferably, the attachment means comprise a key formed on the head assembly and a correspondingly proportioned key-way formed on the shank. The fixed reference on the shank is its bottom surface and the predetermined positions on the attachment means are the lowermost abutting edges of the key and key-way. In addition, any increase or decrease to the cutting height is added or subtracted at the bottom surface of the shank. Advantageously, the tool bit head assembly includes only a support plate which supports the tool bit insert and on which the key is formed and a clamp member which is fastened directly to the support plate to clamp the insert against the support plate and which includes locating means cooperating only with the support plate for positively locating its clamping arm portion with respect to the desired location for the tool bit insert.
