Top Jaw Forming Device

If you have used plugs or adjusting spiders to form top jaws, you know how difficult and frustrating these methods can be. Once you try Huron’s Top Jaw Forming Device, you’ll see a real improvement in accuracy and productivity. And you’ll wonder how you ever got along without it. We guarantee it!

It attaches quickly, with no tools. It can be used to set up a wide range of I.D. or O.D. workholding. And its self-centering action gives you equal pressure on all jaws. Most importantly, the Huron Forming Device compensates for “jaw lift”, even in worn chucks, resulting in better T.I.R. of parts.

Top Jaw Forming Devices are available in three sizes: to fit 6″ chucks, 8″ to 13″ chucks and 12″ to 18″ chucks. The Huron Forming Device is built to last, with heavy-duty construction, a heat-treated scroll and jaws machined from 4140 steel. No casting or stampings are used.
