WhizTwin Parting-off inserts

 

WhizGuide - Select the ideal parting off insert

   
 

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 the centre hole.
 
 

2. Cutting rake options

  • 2° range, flat design, for soft short chipping materials, really tough materials and very small parts.
  • 7° range, for steel applications, where maximised corner strength and a chip control is needed. For alloyed steels, super alloys, hardened materials. Honed cutting edge only.
  • 12°, universal chip control that works in most materials. Excellent in unalloyed steels, stainless steel, and titanium.
  • 18°, the most steep cutting rake, with a soft chip control. Perfect for any material that has problems with built up edge, chippacking. Perfect for 316L 400 series stainless, titanium in good conditions (vibration free).

 
 

3. Corner alternatives

  • Most inserts are available with sharp or radius corners.
   
 

4. Make it stable

  • Clamp the tool holder so the cutting edge is as close to the tool plate as your setup can allow.
  • Choose as short MAX Ø insert as possible.
