Guys, I'm looking to dive into the wonderful world of 3D cutting. Ive looked at several sites that sell ball nose bits and have noticed that in every case the shank diameter is the same as the CED. This means that if I want to purchase bits of 3/16", 5/16", 7/16", 3/8, etc., I would need inserts (sleeves) to hold them in the collet nut. Currently I am set for 1/8", 1/4" & 1/2" shanks only.
How can I solve this problem and where are some of you 3D cutters getting your bits and sleeves? I use the Milwaukee 5625 router and still have my old PC. Thanks.
