100R Series

Tool 100Rm050LFA

Heavy cuts in large work generate heat fast. The 100Rm050LFA handles 5-inch diameter roughing passes in steel, iron, titanium, and nickel alloys without thermal failure. TiAlSiN coating adds a thermal barrier that lets the tool run hotter cuts while extending edge life in abrasive materials.

The 4-flute design with chipbreaker geometry breaks chips before they can pack or weld to the cutting edge.
That 0.1" chamfer strengthens the corner where most roughers fail first.
It distributes cutting forces instead of concentrating them at a sharp edge intersection.
You get predictable tool life even when pushing feed rates.
This isn't a finishing tool.
Surface texture will show tool marks and require a finishing pass.
But for hogging out material in production environments where cycle time matters, it removes stock without the chatter or premature failure you get from standard end mills run too hard.
