Tool 170i750M030A

Heavy cuts in steel generate heat that breaks down cutting edges faster than the spindle can compensate with speed. The 170i750L030A distributes that thermal load across seven flutes while the TiAlSiN coating acts as a thermal barrier between the carbide substrate and the workpiece.

Seven flutes reduce chip load per tooth at higher table feeds, keeping individual cutting edges within their thermal limits.
The R0.03" corner radius strengthens each cutting edge against chipping while maintaining the sharp geometry needed for efficient material removal.
TiAlSiN coating extends tool life in steel, iron, titanium, and nickel alloys where heat buildup typically limits performance.
The 0.75" diameter provides good rigidity for interrupted cuts and varying engagement conditions.
Requires consistent spindle speed and adequate coolant flow to manage chip evacuation through seven flute channels.
