Hello,

We have a CNC XYZ router with a Bosch spindle. It accepts endmills with a 1/4" shank. We have an assortment of endmills: mostly 1/4", 1/8" and 1/16". The router has a single collet which takes 1/4" shank bits. In order to use 1/8" endmills as well as 1/16" ones, we need either to change the collet or to use a collet bushing insert. Can someone tell me a single vendor which carries the 1/4" to 1/8" reducer insert as well as a 1/4" to 1/16" insert. I have only found 1/4 to 1/8 reducers and 1/8 to 1/16 inserts but no 1/4 to 1/16.

Thanks
Mike
