Cutting data:
vc = 150 m/min
n = 2075 rpm
f = 2.1 mm/rev
fz = 0.35 mm/rev

  • Tool life increased by 333 %
  • Competitor produces 250-1500 holes.
  • Surface is poor, diameter is reduced quickly.
  • Costs so far: € 0.10/hole for 1500 holes.
  • With Reamax TS, a tool life of approx. 5000 holes.
  • Costs now: € 0.04/hole
  • Saving: € 60000/year
  • Diagram above: Very good, tightly rolled chips - removal in direction of reaming
