Each collet is precision-ground on all critical surfaces, so they grip tooling securely with a total runout less than 0.
0006 inches.
The carbon steel construction gives them good elasticity and strength, so they hold up to repeated clamping cycles without losing grip.
And they're super easy to identify – each collet is packed in its own labeled protective container, plus the size is marked right on the collet itself.
No more squinting at tiny stamps or mixing up sizes.
Whether you're running a CNC mill, a manual lathe, or an engraving machine, these collets are a solid, no-nonsense choice.
