CNC Endmill

Computerized Numeral Controlled (CNC) Endmill  is a specialized software used to send automated milling instructions or a ‘toolpath’ to the machine which then cuts away a design in your stock material. For most operations, CNC machines use end mills that cut laterally (side to side).

End mills have cutting surfaces called flutes. The most common end mills have two to four flutes. Generally, fewer flutes evacuate more chips from your material, keeping the bit cool. However, more flutes produce a finer edge finish. There are four basic flute types, each optimized for different materials and edge finish. Solid carbide or carbide tipped are ideal since they don’t dull as easily as HSS (high speed steel) end mills.
