low TIR means less wear and tear on spindle bearings
Based on the ER20 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.
