Tool 150i375L030A

Harder alloys fight back with work hardening and heat buildup. The 150 Series spreads that load across five cutting edges instead of the typical four.

Lower chip load per tooth at equivalent feed rates means each edge works less while maintaining your cycle time.
The TiAlSiN coating handles the thermal stress that comes with steel, iron, titanium, and nickel alloys.
Particularly when surface speeds push into the range where uncoated tools start breaking down.
That 0.006" corner radius prevents the sharp corner fractures common in interrupted cuts while maintaining edge strength for semi-finishing operations.
Five flutes deliver the surface finish quality you need in harder materials without backing down on feed rates.
Half-inch cutting diameter gives you the rigidity to use that geometry effectively.
