Drill LU(effective flute length) Re(effective flute length) LCF R OAL L ISO 13399 standardizes not only the format of 2D and 3D CAD data but also the tool dimension symbols (properties) and reference position information. This allows the tool information to be read and combined into NC programs and CAM software, regardless of any tool maker's data. In addition to the General Catalog (paper catalog), we are also updating the symbols in the e-catalog (electronic catalog on our website) to the properties conforming to ISO 13399. The e-catalog also provides 2D and 3D CAD data in accordance with ISO 13399 standard.
