Tool 100i375LA

Steel work puts constant stress on cutting edges. The 100i375LA handles that stress through controlled geometry and surface treatment. Four flutes spread chip load evenly across each revolution, while TiAlSiN coating adds a thermal barrier that keeps the edge stable when cutting temperatures climb.

The R0.006" corner radius eliminates the sharp corner that typically fails first in interrupted cuts.
Small enough to maintain edge sharpness, large enough to resist chipping when the cutter enters and exits the cut.
In side milling operations on steel and iron, that radius extends tool life by reducing stress concentration at the corner.
TiAlSiN coating performs consistently across the temperature range you see in steel machining.
The aluminum content forms a protective oxide layer at cutting temperatures, while the silicon improves hardness retention.
