Technical guide to grinding high-performance endmills (part one)
This has led to "weird" endmills, with higher geometrical levels of complexity. In high helix tools the cutting forces are directed more vertically and less horizontally, which reduces tool deflection and results in quick and efficient chip evacuation. More positive axial rake lowers cutting forces which helps to increase feedrates.
