Tool 120i156LA

Small diameter ball nose cuts require a coating that can handle heat buildup in confined spaces.

Ball nose geometry at 0.1563" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
The 0.1563" cutting diameter handles precision work on contoured surfaces and mold profiles where larger tools cannot reach.
TiAlSiN coating extends tool life in these demanding applications by dissipating heat more effectively than uncoated carbide.
The aluminum content in the coating maintains hardness at elevated temperatures while the silicon improves oxidation resistance.
Three flutes provide the cutting engagement needed for ferrous materials while maintaining adequate chip evacuation in tight radius work.
The rounded tip produces smooth surface transitions without the stepping marks that square end mills leave on curved geometry.
