Technical guidance & FAQs

Applications and materials

Kennametal HARVI I TE corner-radius end mills support roughing and finishing in steels, stainless steels, cast iron, high-temperature alloys and hardened materials. This metric KCSM15 family has four flutes and a necked plain shank for features requiring clearance behind the cutting section.

Choosing a configuration

Match cutting diameter and corner radius to the feature, then check maximum cutting depth AP1MAX, usable length L3, neck diameter D3 and overall length L. Neck clearance and cutting depth are separate dimensions.

Compatibility and use

Confirm the selected shank diameter against the toolholder. A family image or dimensional drawing does not establish the dimensions of every configuration.

What is the difference between AP1MAX and L3?

AP1MAX identifies maximum cutting depth; L3 identifies usable length in this family's dimensional data. Check both for the selected material number.

Why choose a necked corner-radius end mill?

The corner radius defines the rounded transition at the cutting corner, while the reduced neck provides clearance behind the flutes. Match both to the feature; usable reach does not increase maximum cutting depth.

Which milling operations does the HARVI I TE platform cover?

Kennametal provides guidance for side milling and slotting, alongside roughing and finishing applications. Use the cutting data for the selected geometry, material group and engagement.
