Understanding CNC Torque vs Horsepower - Destiny Tool
Old School End Mills Traditionally, a larger diameter 1" end mill would require high torque and low speed (SFM /RPM), while a 1/4" diameter end mill would require low torque and high speed (SFM / RPM). Generally, different end mill diameters & geometries have different requirements for both horsepower and torque.

7. Positive Vs Non-Positive Drive In the event of tyre failure on the Optiflex Tyre coupling there is no connection between the drive and driven shaft. TRC, Jaw and MC couplings will continue to drive for a period of time after element failure. Optiflex can be used as a shear-pin but never in a situation where the drive should always be maintained.
