Bar Pull Systems to include Metric sizes and new Inch increments


The Dunham Tool Company has expanded its line of Bar Stock pulling Bar Pull Systems to include Metric sizes and new Inch increments. The new Dunham Bar Pull metric sizes include a Dunham 25mm diameter Bar Pull Shank that mounts into a 25mm Boring Tool Holder. The new metric Dunham Bar Pull Grippers now include grippers for bar stock sizes ranging from 3mm to 30mm diameters. These grippers will mount directly to the Dunham Bar Pull Adapters or Bar Pull Shanks. The new Dunham Bar Pull Gripper inch sizes now include 1/16 inch increments from 1 1/16 inch to 2”; therefore the complete range of inch Dunham Bar Pull Grippers now ranges from 3/16 inch to 2 inch in 1/16 inch increments. The lightweight and self-activating Dunham Bar Pull System has no moving parts, mounts in 60 seconds with gripper change in about 30 seconds, and does not interfere with other tools. Requiring only 1/4” of bar stock engagement, the Dunham Bar Puller System pull positions the bar stock within 0.001”. The Dunham Bar Puller Kits are one of a wide range of Dunham workholding devices including 5C, 16C and 3J cartridge spindles, drawtube style collet chucks, air collet chucks, collet actuators, vacuum chucks, dead stop step chucks, machineable expanding mandrels, and 5C, 16C and 3J expanding collets.
