6 Pc. Chuck Adaptor Set (4.0-6.5mm range) & Collets

Goodson Tools & Supplies

If you've ever had small diameter valves move around in the grinder because the stems are too small for your chuck, you need this tool!

The hardened steel body of this chuck adaptor fits any machine with a 1/2" chuck. By using different sizes of collets you can easily adapt to the size valve stem you're working with. The collets seat in the retainer nut for fast, easy removal and come in 4 sizes from 2.8mm to 6.5mm. An internal stop adjusts for valve stem length and adjusts easily with a screwdriver.

The adaptor set comes with the holder, retainer nut and 4 collets (4.00mm, 5.00mm,  5.50mm and 6.5mm). Complete kit also includes stop (VG-STOP) additional sizes are available (sold separately).

NOTE: These collets will NOT work without the holder so you must by the full set first, then replace or add collets as needed.

Watch the following video to see how easy it is to use.
