Tool 200i500Z015C

Aluminum loves to weld itself to sharp corners. Standard square end mills create stress concentrations that invite built-up edge formation, especially on demanding passes where you can't back down on parameters.

The 200i500Z015C carries a 0.015" corner radius that distributes cutting forces more evenly across the edge.
The radius reduces the sharp contact point that aluminum tends to grab onto, while the 3-flute geometry maintains lower chip load per tooth compared to 4-flute alternatives.
TiB₂ coating handles the heat and adhesion resistance when flood coolant isn't enough or when dry machining aluminum castings.
Half-inch cutting diameter gives you the rigidity for hogging operations while the high helix angle keeps chips moving before they have time to reweld.
