What is the right - best bit ?????

[Rtalexand]

This is a terrific thread. Great info. I recently attended the Cabinet Class at ShopBot for the Cabinet Parts Pro software. I had been using 1/4" bits for all my cabinet work. I am semi- retired and have had my ShopBot for a couple of years and am just a hobbyist, but enjoy building cabinets for myself and friends. In the class, Ryan was using a 3/8" mortise compression from Onsrud (60-123 MW) to cut cabinet parts from 3/4" MDF in a single pass on the PRS Alpha. I am now using the Onsrud 60-120 MW (single flute for my PRS Standard) and I cut a single pass on 3/4" Maple plywood. Using the chip load calculator and listening to the bit work, I am running 288 IPM @ 15,000 RPM. I get a great cut that I can take straight to the edge bander. I can cut a full sheet of panels with dadoes and rabbets in under 40 minutes. So far I have cut over 6 sheets using these settings with no degradation in the edge quality. The bit is slightly warm to the touch when it is done with a sheet.

I hope you don't mind a hobby user jumping in, but the cabinet class was very enlightening ... Thanks

Just ordered 2 of the above compression bits.
We shall try these out, compare the cuts, maybe throw some pictures up as proof.

But will probably stick to my standard 60 ipm.
