If you're running a CNC mill or a manual machine and need dead-nuts precision, this Techniks ER32 collet is the ticket.
It's a 3/8\ collet with an insanely tight TIR (runout) of just .0002 inches.

That means your tools spin true, giving you better finish and longer tool life.

It's brand new, still in the original packaging, and ready to work.

The collet range is .336 to .375 inches, so it grabs that 3/8\ tool nice and tight.

Techniks makes good stuff—this is MPN 04232-3/8.
