I'm trying to find a 2 (or more) flute 1/16" upcut router bit with a 1/4" flute length for my CNC router. I tried to use a Onsrud 1/16" single flute cutter but the feed speed is just too slow (broke it). I have a used bit that I got in a $15 "grab bag" of router bits that I was able to use but I haven't found an equivalent replacement for this one if it breaks. It is a 2 flute 1/16" bit with 1/4" flute length. Works great. Anyone know where I can get small diameter router bits with extended flute lengths? I'm cutting 5.2mm plywood 3D puzzles using a 1/16" bit for the best detail and using .08 multiple pass depth cuts.

Try american carbide, not sure if they carry it but wont't hurt to try

Just curious as to how fast you hope to run the 1/16" tool? If you can live with less detail the 60-102 (.125" diameter Onsrud) can give you speeds of 400+ IPM. I'm running one at 120+ IPM/16K RPM and it goes through 1/4" baltic birch in one pass, like butter.

1/16 x 1/4 length of cut carbide 2 flute is $5.18 each.

One thing has become clear to me over the past few weeks, cutting (many) hundreds of shapes in 1/4" baltic birch plywood. Tooling designed for CNC applications is going to offer superior performance over standard woodworking router bits and metal cutting endmills.

You can use any/all of them with good results in different materials, but a tool designed for cutting wood/plywood (CNC applications), is going to outlast and outperform the more generic end mills all day long. You may save a few bucks with the end mills, but your feed rates and surface finish may suffer.

I reduced my cutting time by 70% by switching to the Onsrud bit and the surface quality is off the charts. And I'm still only running at about 1/2 the recommended speed. Once I get my servos installed I'll cut my time in 1/2 again. YMMV.

Steve is correct. My .02 you get what you pay for. Quality CNC tooling will out perform budget tools. It may be grade of carbide or cutter pattern. By investing in better tools you will save your self headache and cost in longer time.
