low TIR means less wear and tear on spindle bearings
Based on the ER20 Collet / Nut architecture, the Think & Tinker PC family
of collets and nuts was designed to bring the precision and flexibility of
expensive high frequency spindles to low-cost, consumer and professional grade
Porter-Cable 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.
