Dunham Tool has further expanded its line of barstock pulling bar pull systems to include select additional inch and metric sizes for use on CNC lathes. The bar pull metric sizes include a Dunham 25-mm diameter bar pull shank that mounts into a standard 25-mm boring toolholder.  

The metric Dunham bar pull grippers now include grippers for barstock sizes ranging from 3-mm to 34-mm diameters in 1-mm increments. These grippers mount directly to the company’s bar pull adapters or bar pull shanks.

The bar pull gripper inch sizes include 1/16" increments from 1/8" to 2" diameters, and 1/8" increments from 2 1/8" to 3" diameters. Therefore, the complete range of inch bar pull grippers range from 1/8" to 3" diameters. All Dunham bar pull system components are available individually or in a variety of kits and are available from stock.

The lightweight and self-activating Dunham Bar Pull System has no moving parts, mounts in 60 seconds (with gripper change-over in about 30 seconds) and does not interfere with other tools on the machine turret or gang tool table.

Requiring only 1/4" of barstock engagement, the bar pull system pull positions the barstock within 0.001".
