High Efficiency Drilling for Steel Indexable 3 flute 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.

Workpiece clamping condition
SCM440 200mm square x 120mm height block
New design 3 flute drill head
2 flute drill head for steel machining
2 flute drill head with self-centering design12xD machining is available without prepared hole.
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:
Vertical line shows expanded diameter value (μm) *The numbers inside the parentheses shows feed of ICP and HCP.
H3P (3 flute drill) is excellent hole accuracy even at high speed machining.
Hole surface condition(Vc=80m/min)
Processed with HCP is the smoothest surface. H3P (3 flute drill) is better surface than ICP.
Recommended cutting condition
Additional test: Excellent machining on FC200 workpiece as well!!Vertical line shows expanded diameter value (μm) *The numbers inside the parentheses shows feed of ICP and HCP.

High speed machining on steel and cast material
It is possible to process at higher feed speed by indexable 3 flute drill.
Extend tool life
3 flute drill is longer tool life than 2 flute drill.
This product is available for SS400 which the chips become longer shavings.
This product is available for FCD600 that is hard workpiece.
