Dynamic Chip Flow

The Chip Splitter end mills are available in a 5- and 7- flute configuration for maximum feed rates in dynamic milling operations. Both feature unequal flute spacing for vibration dampening with geometries designed to perform on Steels, Stainless Steels and Super Alloys. The design includes small chip splitters along the cutting edges to break the chip into shorter sections without reducing the wall finish. Shorter chips are easy to evacuate from the cutting area, especially when machining deep cavities. Chip Splitter end mills are the natural evolution of the successful VariMill™ II and VariMill™ III geometries.

Features:

  • Chip splitters to break the chips into small segments making them easier to evacuate
  • 5-flute geometry for Steel applications
  • 7-flute geometry for Stainless Steel and Super Alloy applications
  • 4.5xD Ap1 Max to enable maximum metal removal rates (MRR)

Increased Tool Life, High MRR, & Less Downtime

Dynamic

Evacuates chips in dynamic milling operations with complex toolpaths. The Chip Splitter end mills are developed mainly for the Aerospace industry, but they are applicable to all customers requiring dynamic milling strategies to increase tool life on difficult-to-machine materials.

Efficient

Utilize the full feed rate machine capabilities with the 5- and 7-flute configurations. Dynamic milling processes are typically run using a low value of radial engagement which generate a thin chip thickness, which will then allow higher feedrate-per-tooth values and a consequent high MRR.

Steady

No more machine downtime due to tool breakages and bad chip formation. The machine will keep running while the chips are flowing.
