low TIR means less wear and tear on spindle bearings
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.
