I’ve done 0.2 DOC at 100ipm with a similar bit before, but only using adaptive clearing with Fusion. That keeps a constant load on the tool. I’d say 0.25 at 140 is a lot for the router and machine, but should be doable.

If you are cutting hardwood, we would recommend a starting speed rate at 17,000 RPM and a feed rate of 140 inches per minute at .250” depth per pass with a chip load of 0.005” per tooth. Please adjust your speed and or feed rates accordingly in 10% increments to achieve your desired finish.

Using a 1/4" flat endmill, 2 flutes, you can safely rough at 0.125 DOC and 100ipm. I’ve recently done 0.25 DOC at 80ipm without a problem.

Depends on the bit and material but I would say you can increase depth of cut per pass to 0.125 and shoot for 150 to 200 safely from my experience. I often am 300 ipm roughing but that is often allowed down by curves

This was posted in the Q&A section on the Amana 45982 bit page for the “Amana 45982 Carbide Tipped Bowl & Tray 1/4 Radius x 3/4 Dia x 5/8 x 1/4 Inch Shank”.

I’ve tried .25” depth of pass and things rattle and gets very sketchy that is why I reduced it to .08 with a .375 step over and 100 ipm. This was perfect Bc it was fast and I just did a cleaning pass at the end.

My question is the roughing feed and speed for 1/4 end milll. I know what for for the bowl bit but was wondering if the 1/4 end mill will be the same.
