100 Series

Tool 100i500Z015A

Most shops know the sound of a corner radius failing mid-cut. The sharp pop, then the telltale chatter that means you're pulling the part to check for chips. The 100 Series carries a 0.015" corner radius specifically to avoid that conversation with your setup guy.

Four flutes keep chip evacuation steady in steel and iron work, but it's the TiAlSiN coating that extends the conversation in harder nickel alloys and titanium.
The aluminum content in the coating forms a protective oxide layer at higher cutting temperatures.
Exactly where these materials want to work harden if you let them.
In slotting operations, that corner radius distributes cutting forces more evenly than a sharp corner.
Less stress concentration means less chance of micro-chipping, which means the edge stays predictable longer.
Fewer tool changes per shift.
