HEULE proposd the SOLO S2 tool. Quick blade changes and no need to deburr after the SOLO tool were major advantages over the previous tool. Also, using an indexable ISO standard insert helped with the cost savings. 

Machining parameters:

  • Speed: 700 RPM
  • Feed: 0.15 mm/rev 


By going with the HEULE SOLO back counterbore tool, the distributor in
this account was able to document (and have approved by management) a $13,249.55 per
machine yearly cost savings. With 5 machines, this equaled $66,247.75 annual cost
savings on top of 181.33 hours per year of time savings.
