Available INNOT grades

Grade	ISO	Coating	Composition	Application
IT5225 ★	P · M · S	PVD	Multilayer PVD	First-choice grade for threading: steels, stainless steels and superalloys, excellent resistance to profile wear.
IT5125	P · M · S	PVD	Multilayer PVD	Tough grade for threading in unstable conditions and interrupted cuts on steels, stainless steels and superalloys.

★ Recommended grade. On request also CVD grades for steels and cast irons, uncoated carbide for aluminium and cermet for finishing.

Tips for use

Decreasing depth of cut: lighter passes as you approach the thread root.
Flank infeed (modified infeed at 3–5° on the flank) for better chip control and longer insert life.
Choose the shim according to the thread helix angle: flanks that do not rub and a correct profile.

Which insert for your thread?

Tell us the thread (e.g. M20×2.5 external or 1/2″ NPT internal), material and toolholder: we tell you insert and grade with the quote.
