When measuring the tool length, an internal contact/non-electric type or laser tool setter is recommended. Note 2) Recommended for finish cutting only. Note 3) The tool contact part differs between the nose radius and tangential form radius depending on machining geometries and tilt angles. Select suitable cutting conditions according to tool contact parts. ae RE2 RE1 h ap I181
