Helical Cutters

Helical milling is a hole-making process in which the milling tool proceeds a helical path while rotates around its own axis, presenting several advantages in relation to conventional drilling. The helical path can be decomposed into axial and tangential directions, combining frontal and peripheral cutting. However, the helical cutter provided six times the tool life of the high-feed mill and a 40% increase in metal removal rate. The end result was a cycle time reduction of 60%, which, over the course of a year of machining, created more than $40,000 in savings.
