45 deg High Helix End Mill


Richards Micro-Tool  has introduced a new line of 2-flute, 45° High Helix carbide end mills designed for use in non-ferrous precision metal-cutting applications. The 45° High Helix carbide end mills feature a sharper cutting edge to improve cutting entry and action without having the tool become work hardened. 

The design allows higher feed rates without chip packing, and can be used for plunge, ramp or profile milling. Richards’ 45° High Helix carbide end mills are available in a range of end-mill diameters ranging from 1/32” to 1/4” fractional, and .015” to 0.93” decimal. Specialty coatings are available, including a Titanium Aluminum Nitride (TiAln) coating for difficult-to-machine materials such as stainless steel and titanium.


  • sharper cutting edge
