Efficient parting off tools

At WhizCut, we prioritize lowering production costs and boosting productivity for our customers. WhizTwin parting off tools achieves both, optimizing machining processes and significantly cutting costs without sacrificing productivity.

Benefits of WhizTwin double edged parting off

  • Optimize material: WhizTwin’s dual-edged design maximizes material use and stability, making cutting and parting more efficient and reducing waste.
  • Less vibrations: Two cutting edges at the front allow the holder to be clamped closer to the tool plate.
  • Chip control: Choose from four chip control and cutting rakes to enhance performance for most materials.
  • Material and barstock savings: WhizTwin’s stability allows for a narrower part off, saving material.
  • Reduced energy consumption: WhizTwin’s efficiency cuts machining time and energy use.

Reducing the challenges of parting off operations

The WhizTwin design allows the tool holder to be clamped in a more stable position with a shorter overhang from the tool holder plate, significantly reducing instability and vibrations, which are the primary challenges when parting off with precision cutting tools.

The narrow insert helps lower production costs by minimizing material waste. Using less bar material not only saves money but is also beneficial for the environment.

Stability

Stability all the way to the front. By having both cutting edges at the front, the mass from the below cutting side gives stability to the upper cutting edge.

Reduces vibrations

By placing both cutting edges at the front of the insert, WhizTwin harness the carbide mass and support from the lower cutting side to stabilize the upper cutting edge. This design minimizes vibrations, ensuring a more stable performance during machining operations.

Reduced overhang

Minimized overhang — parting off close to the tool holder plate. The reduced overhang boosts stability in the machining process.

Choose the ideal inserts for parting off

1

Straight or angled part off

  • Style P: 0° gives the strongest tool. Suitable with use of sub spindle.
  • Style Z: 15° Suitable to be used without a sub spindle or when parting off with a center hole.
2

Cutting rake options

  • 2° For short-chipping materials, and very small parts.
  • 7° For steel and other tough materials when an aggressive chip breaker is needed.
  • 12° The best overall choice. For long-chipping materials, and strong enough for tough materials.
  • 18° For sticky long-chipping materials and materials where there is a risk of a built-up edge.
3

Make it stable

  • Clamp the tool holder so the cutting edge is as close to the tool plate as your setup will allow.
  • Choose as small MAX Ø on your insert as possible.
  • Use the tool holder as probing/bar stop instead of the insert.
