Button insert milling cutters for blade milling and profiling

Successful and productive in high performance cutting

The extremely robust and compact cutter body with positive mounting position in combination with the inserts produces minimum cutting forces and reduced vibration. This ensures that MaxiMill 251-RS can also be applied on machines with low spindle power. In particular the milling system shows excellent suitability for rough machining and difficult to machine materials.

Economic and manageable with numerous indexes

The button insert of the milling system MaxiMill 251-RS is provided with 4, 6 or 8 indexes. The differing indexes on the insert ensure the insert can be optimised for the depth of cut required.

- Stable and compact cutter body with very positive rake angles up to 18°

- Diameter range from 10–125 mm

- Inserts with 4, 6 or 8 indexes

- Inserts with positive clearance angle

- High performance grades

Carbide properties:

- Extremely heat-resistant

- Very tough

- Excellent resistance to notching

- CVD high performance coating with maximum hardness and smooth surface
