High Feed End Mills

Designed for high feed applications, High Feed End Mills take advantage of chip thinning with a specifically engineered end profile to increase machining efficiencies. Similar to High Efficiency Milling (HEM) techniques, the milling technique for these tools allows for drastically increased feed rates to maximize chip thickness and keep radial forces low.

Combination Feed & HEM

Helical's Combination Feed and HEM Mills, designed for both high feed and High Efficiency Milling (HEM) applications, offer outstanding performance and high temperature resistance in a wide range of ferrous materials, including low and medium alloy steels, tool steels, cast iron, titanium, and titanium alloys. These Tplus coated tools are offered in 4 and 5 flute styles.

Steels up to 45 Rc

The specially engineered end profile featured on Helical's High Feed End Mills works to minimize cutting forces, while its reduced neck geometry provides maximum strength in long reach and deep pocketing applications. These tools allow for drastically increased feed rates, enabling maximized chip thickness and low radial forces when machining in steels up to 45 Rc.


Helical's fully stocked offering of High Feed End Mills is designed for outstanding performance and maximum feed rates in aluminum and non-ferrous materials. Its reduced neck geometry provides maximum strength in long reach and deep pocketing applications, while its end profile provides optimal tool engagement and reduced cutting forces.
