Test Report:




Summary:
Tools tested: Ø10 mm with internal coolant 3 flutes vs 2 flutes.
Materials tested: AISI 4340 / DIN NiCrMo6
Cutting conditions: first 1200 holes feed 0.12 [mm/t], then 0.17 [mm/t]

Test Results:
2 flute tool performed 1450 holes (until end of tool life).
3 flute tool performed 2000 holes (until completion of test).
Due to the extra tooth, the 3 flute drill performed 1.5 times faster.
