A typical end mill may be referred to as an "Upcut Spiral" by the CNC Router world. Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable. The more common spelling is "end mill", but I often use "endmill" as well. The two are pretty interchangeable. Carbide vs HSS End Mills

Different endmills really do perform differently, and they sure do come in a wide range of prices. In this article, we'll take a look at the four main factors that cause end mills to perform differently: the grade or quality of the carbide they're made from, their geometry, the end mill coatings, and premium quality control.

A rotary cutting tool is disclosed including a substantially cylindrical main body having a shank portion at one end and a point at an opposite end. Five flutes are formed in an outer surface of the main body. Each of the flutes extends continuously from the point to the shank portion, and defines a helical cutting edge having a helix angle between about 32 degrees and …

An angular feature ground onto the surface of an end mill. Axial rake – The angle formed by a plane passing through the axis and a line coinciding with or tangent to the tooth face. Effective rake – The rake angle influencing chip formation most.

Design procedures of end millsEnd mills are generally used in mechanical machining. The parameters of geometry shapes of end mills are the helix angle, rake angle, relief angle, clearance angle, and the land, etc (United State Cutting Tool, 2004). These values are related to materials of machining, and affect the cutting performance and tool life.

End Mill Side Clearance • Primary (1st angle, 5°- 9°) – Relief Adjacent to Cutting Edge • Secondary (2nd angle, 14°-17°) – Relief Adjacent to Primary Angle • Tertiary (3rd) – Additional Relief Provided Adjacent to the Secondary – High Performance End Mills

Standard end mills are offered with helix angles as low as 15° to as high as 60° angles. General-purpose end mills are generally around 30°. Any increase in the helix angle increases the effective shearing action thus reducing cutting forces and the amount of heat generated during the milling process.
