machining nitralloy type 135

[kellybilly]

i have been trying to find an insert that will hold up while turning nitralloy 135. an insert grade for roughing and finish turning along with spindle speeds and feeds would be helpful. any info would be appreciated

 

Everybody knows the Kennametal C6 grades are superior for this material

 

Almost everybody knows that Sandviks MT-CVD grades kick the K out of ennametal. Check out the 4025 for roughing and the 4015 for finishing.
