1 1/8 Inch Collet
These expanding collets will firmly support your stock or bi-laminate lugs, bottom brackets, and fork crowns. They are designed to be used with the Wilton 343 Work Positioner (We have included a link at the bottom in case you are interested), but they are also easy to adapt to alternate set ups.
When combined with the work positioner you have endless options of position and orientation along with solid support. All collet bases are machined to a 1" diameter and tapped 3/8X16NC. They are handy when supported in frame blocks and easily attach to alternate set ups with a simple bolt at the base. Flats are machined for a 3/4" wrench simplify collet set up and locking down the work. Made in steel.
For custom sizes please give us a call as there is a 2 week lead time.
