Tool 150i500L015A

Built-up edge becomes a problem when machining steel at higher speeds. Heat and pressure cause work material to weld onto the cutting edge, degrading surface finish and accelerating wear.

The TiAlSiN coating on this 150 Series end mill addresses that issue directly.
Aluminum content in the coating creates a protective oxide layer at cutting temperatures, reducing friction and preventing material adhesion.
Five flutes distribute heat load across more cutting edges, keeping individual edge temperatures lower during semi-finishing operations in steel, iron, titanium, and nickel alloys.
The R0.03" corner radius strengthens the cutting edge while maintaining good surface finish capability.
Sharp corners cut cleanly but chip easily under interrupted cuts or when entering hardened zones.
This radius provides the edge strength needed for consistent performance in variable conditions.
Half-inch cutting diameter handles most general machining requirements.
