convert rf45 type to belt variable speed and some cnc info?
WEBAug 31, 2006 · Even when using a 3/4" end mill you still want at least 1500 in aluminum and 750 in steel for optimum material removal. The only appliion I can think of requiring high torque / very low speed is when drilling very large diameter holes ( 5/8" + ) with a drill bit. If its CNC, you can mill them.
