Astra Coated 3 Pc Aluminum Bit Set

Match this with any i2R Series CNC. This Bits & Bits set includes one of each Astra coated bit. 

  1. SRF43-250GP – .25″ Upcut Flat End 3Flute Bit.  Square end center cutting 3 Flute End Mill for high speed milling on aluminum & wood and non-ferrous materials.
  2. SRB43-250AM – .25″ 3 Flute ball nose. This tool features a 45 degree helix which makes it ideal for finishing due to its high shear angle and cutting aggressiveness. 3 Flute end mills are perfect for milling aluminum and other soft metals, they also tend to reduce vibrations during the milling operation.
  3. 425-VG45 45Degree V-Groove Bit – V-bits produce a “V” shaped pass and are used for engraving, particularly for engraving letters and making signs. The small angles and tips provided on these V-shaped engraving bits produce narrow cuts and small, delicate engraving of lettering and lines.  Excellent for cutting: Aluminum, Plastic/Acrylic, Brass Wood

How does Bits & Bits’ Astra Coating extend the life of your bits?


During any type of cutting process, the cutting bit endures heat created by the friction and abrasion of the bit moving through the material. This friction and abrasion is a major cause of bit wear, resulting in the cutting edge dulling or deteriorating, causing burning, a rough finish and vibration.

Astra Coating is an applied multi-layered surface coating that lowers the friction coefficient of the bit, which allows the bit to cut smoother and faster while keeping friction heat down. This in turn will extend the life of the bit. Astra Coating is effective in wood, metals, aluminum, brass, and plastics, allowing faster speed and feed rates.
