RD Type Automatic Pull Head
The RD pull head is recommended for pull down broaching operations where chips fall or are washed downward by coolant onto the pull head. The special design of the head provides an umbrella top to shed falling chips and a hole the length of the puller for chips to wash through. This head is identical in operation to the R Type and can also be provided with a radial index key. This puller fits all standard broaching machines.

R Type Automatic Pull Head
This four jaw broach pull head assures positive and automatic broach connection on horizontal or pull-up broaching machines. When the broach connects, a coil spring moves a sleeve forward engaging and locking all four jaws around the broach shank. The broach is disengaged by contact of the sleeve against preset stops, which moves the sleeve back, unlocking the jaws. The puller can be provided with a radial index key. This puller fits all standard broaching machines. View the R Type Automatic Pull Head Size Chart and Cross Section Drawing.
Round Pin Type Broach Pull Head
Pin type pull heads are used to handle broaches less than 1/2" in diameter. The broach shank is securely held in position by spring pressure on the cross pin. Removal is effected manually by a slight pressure on the cross pin. Automatic release is provided by a plunger above the broach bore, causing the cross pin to recede on contact with a preset stop. For radial broach positioning, index cross keys are inserted into the pull head to provide proper alignment. View the Round Pin Type Broach Pull Head Size Chart and Cross Section Drawing.
Horizontal Keyway Puller Designed primarily for keyway broaches or types of broaches using rectangular shanks, this pull head can be manually or automatically operated. Proper pulling alignment is assured as the head holds the broach in position against flat surfaces and provides a positive broach locking action. The keyway broach pull head is built in two sizes, the number (0) for broach shanks up to a maximum 3/4" x 3/4" and the number (1) head for shanks with a maximum of 1 1/2" x 1 1/2".
