High-Precision 1/4-3mm Collet Adaptor for 1/2" Shank CNC Routers

This precision-machined 1/4-3mm inch reduction collet adaptor for 3mm shank router bits (made in the USA) is designed for CNC creators who expect professional workmanship from their CNC routers and projects.

It is made with the precision required for CNC machining when you need 3mm shank bits to precisely fit your 1/4" collets. Works for all ER-style collets as well.

This collet adaptor will fit any spindle that has a 1/4" standard collet size

This collet, considered a 'precision-fitted collet', is made from 4140 steel for high wear resistance and is machined to 0.001" tolerances. This collet by IDC Woodcraft ensures your CNC router bits run exceptionally true and significantly reduces the opportunity for bit slipping.

Using ANSI industry standards, IDC Woodcraft ensures this collet is manufactured to machining-level tolerances for an extremely precise match-up between 1/4" collets and 3mm shank router bits., virtually eliminating ‘tool runout’. 

Make sure your 3mm shank CNC bits run true. Use ultra-precise tools whenever possible.
