* Standard edge geometries are not suitable for reaming titanium and high temperature alloys. In order to choose a proper geometry, please ask for our recommendations.
• The given cutting data recommendations refer to the short holders (3xD effective reaming overhang). For longer holders, the cutting speed should be reduced proportionally.
• For relatively large leading angles (spot-facing geometries), the feed should be reduced up to 30%.
• All the given cutting data recommendations refer to the machines with spindle through coolant supply.
