product_Milling_DoOcto

Ideal for steel and cast iron face milling!

A single cutter body with 4 insert options broadens its application range.

Applications & Features

Face millingCoolant hole

1. Inserts are available in single-sided or double-sided geometry

  • ONMU / ONHU: Double-sided, octagonal inserts (economy)
  • SNMU / SNHU: Double-sided, square inserts (large cutting depths)
  • OWMT: Single-sided, octagonal insert (with low cutting load, high feed rates)

2. Enhanced cutter body lineup

• Including cutter diameters of >ø315 mm or extra close pitched design for effective cast iron milling

 



For general purpose
Optimized orientation of coolant outlet which is located in a large chip gullet facilitates smooth chip evacuation. Large clamping screw enhances insert security.
Cutter diameters: ø80 mm – ø315 mm



For efficient cast iron milling
Offers twice as much insert density as a screw clamping style cutter with easy indexability.
Cutter diameters: ø80 mm – ø160 mm
