SSI- 4
Four Flute, Metric

The SSI-4 is the foundation on which our variably indexed family of ferrous rougher/finishers was built. The SSI-4 is a proven, performance driven, ferrous rougher that has the geometry to successfully venture into finishing territory as well. Now updated and expanded to over 70 stocked sizes, we hope that the SSI-4 will be the “go-to” tool for most of your ferrous alloy applications.  SSI-4 Four Flute Metric End Mill
