Two things set the numbers on the OneFinity Foreman: how fast the Makita RT0701C spins, and how much the frame can take without chattering. It runs a working range of about 10,000 to 30,000 RPM, on ball screws. The OneFinity Foreman is one of the stiffer hobby machines, so it can take deeper passes than most before it starts to chatter.
So for a 1/4" two-flute bit in softwood, a sensible starting point on the OneFinity Foreman is around 17,000 RPM and 102 inches per minute, taking about 0.1125" per pass on a slot. The full chart below covers the materials you are most likely to cut. These are conservative starting points: always test on scrap and let your ears do the final tuning.

Numbers are generated by our feeds and speeds calculator using the OneFinity Foreman's spindle range and a stout-frame rigidity factor. Aluminum needs a single flute plus lubricant. Always confirm your bit maker's chart and test on scrap.

What RPM should I run on a OneFinity Foreman?
For most wood with a 1/4" two-flute bit, 17,000 RPM is a good starting point on the OneFinity Foreman. Its working range is about 10,000 to 30,000 RPM. Go higher for smaller bits and finer detail, lower for big bits and heavy stock removal.
What feed rate should I use on a OneFinity Foreman in hardwood?
Start around 100 inches per minute with a 1/4" two-flute bit in oak or maple on the OneFinity Foreman, at roughly 20,000 RPM. Listen to the cut and adjust: clean chips mean you are dialed in, fine dust means you are going too slow.
Can a OneFinity Foreman cut aluminum?
Yes. The OneFinity Foreman is rigid enough for light aluminum work with a single-flute bit, shallow passes, and plenty of lubricant or air. Keep the chipload small and the depth per pass well under the numbers you would use for wood.
