Millimeters Per Revolution (MMPR) — Feed rate of the cutter each revolution of the cutter. In the metric system, the feed rate of the cutter can be calculated for each revolution of the cutter. M.M.P.R. = Chip load x Number of flutes; Meters Per Minute (MPM) — The cutting speed of the end mill. This system is used in all countries that use ...

Mill Calculator. Speeds and feeds are based off of stub, standard or neck relieved lengths only. Flood coolant recommended. Check back often as we're continually adding new product speeds and feeds …

Cutting generates a lot of heat, making oil based coolant preferable. Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low. If not using coolant, then max surface speed …
