Mitsubishi CCMT060204 VP15TF Carbide Turning Insert – CVD Coated for Steel & Stainless Machining
Precision-engineered for high-efficiency external turning of carbon steel, alloy steel, and stainless steel. Engineered with Mitsubishi's advanced CVD multi-layer coating for superior wear resistance and extended tool life.
Product Overview
"Which carbide insert is best for finishing and semi-finishing carbon steel and stainless steel on a CNC lathe?"
The Mitsubishi CCMT060204 VP15TF is a 80° diamond-shaped (rhombic) carbide turning insert designed for finishing to semi-finishing operations on steel and stainless steel workpieces. The VP15TF grade features a CVD multi-layer coating (TiCN + Al₂O₃ + TiN) applied over a fine-grain carbide substrate, delivering an exceptional balance of hardness, toughness, and thermal resistance.
The 04 chipbreaker geometry (medium-light chip control) produces tight, manageable chips at moderate feed rates, reducing vibration and improving surface finish — ideal for precision turning applications where Ra values matter.

Customer Reviews
"Running these on 4140 alloy steel at 280 m/min — surface finish is outstanding. Tool life is noticeably better than the competitor grade I was using before. Will be ordering in bulk."
"Sehr gute Standzeit bei der Bearbeitung von 1.4301 (304 Edelstahl). Die TF-Spangeometrie erzeugt kurze, saubere Späne. Klare Empfehlung für Finishing-Operationen."
"Ottima qualità per la tornitura di acciaio al carbonio. Ho ottenuto Ra 0.8 su alberi in C45 senza problemi. Spedizione rapida e imballaggio professionale."
"VP15TFグレードはSUS304の仕上げ加工に最適です。切削抵抗が低く、工具寿命も安定しています。三菱マテリアルの品質は信頼できます。"
"Used these for a batch of 316 stainless shafts. Consistent performance across the whole batch — no premature edge failure. The R0.4 nose radius gives a great finish."
"在加工45号钢时表现非常稳定，切削速度250m/min，进给0.15mm/rev，表面粗糙度Ra1.6轻松达到。性价比高，会持续采购。"
"Excellent insert for automotive shaft production. We machine 42CrMo4 steel and these inserts last 30% longer than our previous supplier. Highly recommended."
Frequently Asked Questions
💡 Grade Selection Tips – Mitsubishi VP Series
- VP05RT / VP10RT: Best for high-speed finishing of hardened steel and cast iron. Maximum wear resistance, lower toughness.
- VP15TF (This Product): Ideal balance for finishing to semi-finishing of steel and stainless. Most versatile grade in the VP series.
- VP20RT / VP25RT: Choose when machining interrupted cuts, forged surfaces, or variable stock allowances in steel.
- UE6110 (PVD): Prefer for low-cutting-force applications, thin-wall parts, or when minimizing heat generation is critical.
- US735 (PVD): Dedicated stainless steel grade — use when machining 316L, Duplex, or super-austenitic grades.
- Rule of thumb: CVD grades (VP series) excel at high speeds; PVD grades (UE/US series) excel at lower speeds with sharp edges.
