Nut-Collet Crossection
Based on the  ER Spring-Collet / Nut architecture, the Think & Tinker family of precision collets and nuts was designed to bring the precision  and flexibility of expensive high frequency spindles to low-cost, consumer and professional grade routers.

The snap-together design and eccentric extraction ring prevents collets from sticking or binding in the tapered spindle bore. Tool removal is consistently easy.

The internal bore of each collet is preloaded to lightly grip the shank of a bit when it is inserted, preventing tools from falling out or shifting while the nut is being tightened.  Please read Working with ER Nuts and Collets.

The requirement that each collet be individually certified means that orders containing
Ultra-Precision and Extreme-Precision collets and collet-kits
may not meet our normal "within one busines day" shipping target
