Calculating speeds and feeds: 3.82 x Surface Foot Per Minute (SFM) / diameter. Part diameter for lathes; tool diamter for mills. So, for example, a 1/2 HSS end mill in stainless (50 SFM) would be 3.82 x 50 / .5 = 382 RPMs.
M5 is actually M5x0.8 (.197-31.75 TPI) and 10-32 (.190-32 TPI) would be (M4.83x0.794). So it's .007 bigger and has a 0.8% shorter pitch. Very close but not the same.
