P175
Provides an excellent balance of toughness, crater and flank wear resistance. Better option for valve seat machining.
Multi Modal Grain Size
Its multi modal grain size suits best for case hardened steels.
Increased Strength
Owing to moderate CBN content and grain size, abrasion resistance, impact strength and toughness exists together.
