Tool 100i750S125A

Most shops know the feeling when an end mill starts losing its edge halfway through a long production run. The 100i750S125A is built to hold that edge longer in steel, iron, titanium, and nickel alloys through consistent geometry and surface treatment.

Four flutes keep chip load balanced across the cutting diameter, which matters most in sustained side milling and slotting where heat buildup can accelerate wear.
The TiAlSiN coating adds a thermal barrier that lets the tool run at higher surface speeds without losing hardness at the edge.
Temperature spikes that would normally start edge breakdown get absorbed by the coating instead.
The 0.125" corner radius strengthens the cutting edge at the most vulnerable point.
Sharp corners cut well initially but fail faster under interrupted cuts and heavy feeds.
This radius extends tool life in roughing operations where edge chipping typically limits run time.
