Balas C series Collets
C4, C6, C8, C10, etc.
Besides Balas (who developed and made these for many years) I've heard that compatible
collets and chucks were offered by Kennametal, Sandvik and others.
In 1982 Somma Tool acquired the Balas collet line.
The only one I know that is still making these is Somma Tool.
Somma Tool calls these Flexi-Grip collets
