Version 7,10 mm Male GonG holder for lathe work, but can be used offhand as well.
Machined on a lathe to .0001 runout and polished to a mirror finish.

Please Note:
This holder will hold any 10mm Male joint.
If using a lathe, it is recommended to leave a distance of 12 - 13mm (1/2") between the jam nut on the tool and the lathe chuck.
It is also recommended that the graphite part of a cold tool be preheated in a reduced flame before placing in the kiln. A cold tool should never be placed in a hot kiln because of the differing coefficient of expansion between steel and graphite.
