100 Series

Tool 100i625S125A

Most shops know the sound of an end mill giving up mid-cut. The edge chips, the finish goes to hell, and you're back at the tool crib. The 100 Series builds edge durability into steel and iron work through geometry and coating selection working together.

Four flutes keep chip load consistent across the cut width.
When you're profiling steel or taking deep slots in iron, that load distribution prevents any single edge from taking excessive heat.
The R0.125" corner radius spreads cutting forces over more edge length than a sharp corner, which means the edge holds up longer in interrupted cuts and reduces the stress risers that start edge chipping.
TiAlSiN coating handles the thermal cycling you get in steel and titanium work.
The aluminum content forms a protective oxide layer at cutting temperature, extending tool life when heat buildup is unavoidable.
