The ADF series is not only ideal for flat-bottom hole applications, it is also compatible with a wide range of hole shapes such as inclined surfaces, curved surfaces, counterboring, half-holes, thin plates, and more. In order to better accommodate manufacturers’ various processing needs, the ADF series has been newly expanded with the ADF-2D, a general-purpose type that can be used for a wide range of machining; the ADFLS-2D, which can be used for machining with long overhang length; the ADFO-3D, which include oil holes that can be effectively used in stainless steel applications; and the ADF-NC and ADFO-NC, which are compatible with small automatic lathes.
One drill does it all – suitable for a wide variety of applications
Features
(1) EgiAs coating for exceptional wear resistance and toughness.
(2) Wide chip room for smooth chip evacuation.
(3) Unique end cut geometry reduces cutting force to enable stable machining.
(4) 20°helical grooves with high rigidity.
(5) ADFO-3D: Sharp gash angle produces chips with fine curl
(6) ADF-NC・ADFO-NC：Short flute length specification to accommodate small automatic lathes.
