Grade Details:

VP15TF: A TiAlN‑based PVD grade combining a fine‑grain carbide substrate with a tough, multi‑layer coating. Ideal for medium‑to‑high‑speed turning of steel, stainless steel and alloy materials.

UE6020: Engineered for stainless steels and heat‑resistant alloys, this PVD grade offers high toughness, superior resistance to built‑up edge and long tool life under interrupted cuts.

US735: A CVD‑coated grade optimized for general‑purpose turning of steels and cast irons. Provides excellent wear resistance and thermal stability in continuous cutting.
