Ingersoll’s SP6H/SP6N series of S-Max high-feed face mills is said to combine robust edge strength and high-feed capability, providing a hybrid approach to machining applications. The high-feed capability is made possible by an 80-degree lead angle for a 5x chip thinning factor. Two insert choices consist of a multi-purpose geometry and a high-shear geometry for titanium and high-temperature alloys. The face mills have ramping capability and a depth of cut as great as 0.072". Each insert provides four cutting edges, which is an economical advantage over comparable two-edge styles. Medium- and high-density cutters are available. Diameters range from 2.0" through 8.0". Some styles are available with through-tool coolant or air delivery.
