Tool 100i500M030A

Heat buildup changes everything in a cut. What starts as a clean operation turns into work hardening, then chatter, then scrapped parts. The TiAlSiN coating on this end mill creates a thermal barrier that keeps cutting temperatures stable through extended runs in steel and titanium.

Four flutes spread the thermal load across more cutting edges.
Each edge gets more cooling time between engagements, which matters when you're pushing feed rates in heat-sensitive alloys like Inconel or 4140.
The R0.03" corner radius reinforces the cutting edge without creating the stress concentrations you get with sharp corners under interrupted cuts.
In steel roughing and titanium profiling operations, that radius extends tool life by distributing cutting forces over a larger contact area.
The coating stays bonded longer because the edge geometry reduces the peak stresses that cause coating delamination.
