DNA Collets (Dead Nuts Accurate) from TechniksUSA are proven to improve carbide tool life significantly.
"Dead on balls Accurate"
The unique design of DNA collets provides the customer with consistent T.I.R. of .0002" readings and accuracy that boost the life of carbide drills. The beauty of this system is that it is used with any standard ER11, ER 16, ER20 & Er32 collet chucks.
Collets can be used in any CNC Milling Rotary toolholder that accepts ER collets, it's the same taper ID taper angle, as well as any standard collet holder in a CNC lathe. It's especially useful for swiss style turning machines, and mill-turn machines that require a higher level of part accuracy.
