Tool 100i750M060A

Corner radius matters more than most people think. Sharp corners chip under interrupted cuts, and chipped corners make undersized parts. The 100i750M060A carries a 0.06" corner radius that spreads cutting forces over more carbide, extending edge life in roughing and semi-finishing operations.

Four flutes distribute chip load evenly across the 0.75" cutting diameter.
That distribution becomes critical in side milling steel and iron where uneven loading causes premature wear on individual cutting edges.
The TiAlSiN coating adds a thermal barrier that keeps the carbide substrate cooler during heavy cuts in titanium and nickel alloys.
The corner radius also reduces stress concentrations at the cutting edge.
In interrupted cuts through scaled steel or cast iron with hard spots, that radius prevents the micro-fractures that turn into larger edge failures.
