ExtraCut 40 2D (F8300)
4 Flute SquareEnd

Features

• Alternate Helix 40°/42°
• Center Coolant Supply
• Chamfer 45°
• Eccentric Relief
• Enhanced Core Size
• Length of Cut 2xD
• Non center cutting
• Optimized Flute Cross Section
• PVD Coated
• Unequal Indexing
• Weldon Flat

Application

• Machining of Ni-based Superalloys (Inconel, Nimonic)
• Milling of Mangan steels that tend to strain hardening at chip formation.

Annotation

• Alternate helix dampens vibrations
• In case that a built-up edge occurs, use rather the F8320 type.
• These materials are characterized by poor machinability. Their machining requires a very sharp edge and smooth flute finish that prevents material build up.
• Weldon Flat Guarantees the Torque Transfer and Prevents the Shank Extracting (microcreeping)
