• ### Understanding CNC Torque vs HorsepowerDestiny Tool

This entry is when the torque curve on your CNC machine is the most important. Older CNC machines where designed to quickly reach peak torque between 12003000 RPM and then drop off. Newer high speed machining centers hold constant torque. We like Constant Torque Because of the unique geometry our tools perform best under constant torque.
