Hard jaws from Dillon Manufacturing Inc. feature diamond-shaped serrations for increased pull down effect which reduce part slippage and push back from using a bar feeder. The aggressive serrations on the gripping surfaces are also ideal for cast parts, scaly parts or parts with imperfections, according to the company.
Manufactured of 1018 or 8620 steel which is then casehardened and coated with black oxide for corrosion resistance, the hard jaws provide long jaw life and great precision with ground locating services.
They are available in different mounting configurations including serrated, T&G, Acme, and square serrated key types to fit all brands of chucks. Dillon chuck jaws are versatile with multiple radiuses for both inside and outside clamping making them ideal for any size run.
Dillon also offers special or modified hard jaws with quick turnaround time, which saves time and money by reducing downtime.
