Diamond Serrations Reduce Hard Jaw Slippage

Hard jaws from Dillon Manufacturing are designed to center the workpiece and grip it equally with each jaw. They feature diamond serrations that drive the workpiece down, reducing part slippage and pushback when using a bar feeder. The sharper the serrations, the greater the penetration, and conversely, the larger the serration flat the less the top jaw will penetrate the workpiece, according to the company.

Manufactured out of 8620 steel, case-hardened and coated with black oxide for corrosion resistance, the hard jaws are said to provide long jaw life and precision with ground locating surfaces. The jaws are available in different mounting configurations including serrated, T&G, Acme and square serrated key types to fit all brands of chucks.

The chuck jaws provide multiple radiuses for both inside and outside clamping, broadening the variety of part sizes able to be run. The company also offers custom, special or modified hard jaws with optimized turnaround time, reducing down-time and costs.
