Tool 100i156A

Small diameter work in tough alloys doesn't forgive inconsistency. The 100i156A earns its place in steel, iron, titanium, and nickel applications by maintaining edge geometry when heat and pressure want to break it down.

Four flutes keep chip load distributed evenly at 0.1563" diameter, where any imbalance shows up fast in surface finish and tool life.
TiAlSiN coating adds thermal barrier protection without building up thickness that would dull the cutting edge geometry.
The coating's aluminum content forms a protective oxide layer at cutting temperatures, extending edge life in interrupted cuts and varying engagement conditions.
Corner radius of 0.004" strengthens the cutting edge against chipping while maintaining sharpness for clean entry in slotting operations.
In titanium and nickel work, that edge strength becomes the difference between completing the run and stopping for a tool change.
