* 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
