What RPM do you run your grain mill at? | Homebrew Talk ...
850 is a bit fast. Shoot for under 500 rpms. I crush with a monster mill hooked up to an ancient 500 rpm drill. Crush was acceptable at full speed, its even better with the drill hooked up to a variac (reduces voltage) set to 35%.

SFM to RPM [ Easy Guide to Surface Speed / SFM in Machining ]
SFM Formula (SFM to RPM Formula) Once you've got a suggested surface speed, it's relatively easy to convert it to spindle rpms. The simple machining formula you'll use is: Spindle RPM = SFM / circumference. Where the circumference is that of the workpiece on a lathe or the cutter on a mill. Given that simple formula, now you know why ...

Fly Cutter RPMs, etc. | The Hobby-Machinist
I'm trying to to determine the proper RPM for this. I know I don't want to go too high since it's not balanced like an end mill. I see a lot of equations for determining RPMs based on SFM and diameter such as: RPM = SFM X 3.82 / D. But, on a manual mill, how do I determine SFM? Thanks.

Saw Blade Diameter, RPMs, and Rim Speed
Say 1850 RPM on motor, 2 inch pulley on motor and 5 inch on arbor, then every turn of the motor gives you 2/5 turns on the arbor. 2/5 times 1850 is 740 rpm on the arbor. If you have an 8 inch blade on the arbor it has a circumference (distance around) of 8 x 3.14159 or 24.9 inches so rev times distance is 740 times 24.9 or 18,426 inches per ...
DRILL BIT RPM CHART - Imperial Supplies
- When drilling hardwood floor boards for trailers, it is recommended that the RPM's and speed of feed is reduced. Reasoning for this is hardness of material and depth of hole being cut. - If using a 5/16" drill bit that will drill through 1-3/8" hardwood board, the recommended rate of speed is 1,500 RPM.
