High Efficiency Drilling for Steel Indexable 3 flute drill

This new indexable 3 flute drill allows high efficiency machining ever!

LOGIQ3CHAM drill

This is an indexable 3 flute drill.
3 flute drill is usually recommended for cast material or aluminum machining since its chip pocket is narrower than 2 flute drill. However, Iscar LOGIQ3CHAM is available with machining on SCM440. This is advantages that other companies do not have.




Comparison test: Machining on SCM440 by indexable 3 flute drill
Result: Steel machining with 3 flute drill is better accuracy than 2 flute drill.

Spindle loan value comparison result:
H3P (3 flute drill) cutting force is higher than 2 flute drill since feed per revolution is higher.
Diameter accuracy comparison:
H3P (3 flute drill) is excellent hole accuracy even at high speed machining.
Vertical line shows expanded diameter value (μm)　*The numbers inside the parentheses shows feed of ICP and HCP.
Surface comparison:
Processed with HCP is the smoothest surface. H3P (3 flute drill) is better surface than ICP.
Hole surface condition(Vc=80m/min)


Chips condition(Vc=80m/min)
