COGO TOOL's technical info

■ Classification of the shank type


we produce the appropriate products under the ANSI(American standard) and DIN or BS(European standard) because of the export regulation and the shank types are the following.



  • Straight shank : the product with constant cylinder-type of shank part.
  • Flat on shank : the product that carved out according to the set screw on the shank part.
  • Threaded shank : the product that made the screws in the shank part.
  • Combination shank : the product that chuck more powerful to the shank part.
  • Taper shank : the product which the shank part forms the trapezoid shape.
  • Whistle notch shank : the product that titled groove is carved out  in the shank part.
■ radial cutting part
<Eccentric type > 
<Concave type>
<Flat type>

 It needs the secondary relief in case of the diameter is large.
In the international trend the eccentric type is used widely and our company mainly produces the eccentric type except for the special application.
The advantage is to maintain the intensity of the cutting edge in the constant relief indicator drop amount, and the tool life is increase in the constant relief angle.
