TCMT090204 US735
Mitsubishi Materials | Stainless Steel & Toughness Specialist
The Mitsubishi TCMT090204 US735 is a high-toughness PVD coated carbide insert specifically engineered for the challenging task of stainless steel turning. Utilizing the US735 grade, it excels in interrupted cutting and prevents the "built-up edge" (BUE) common in gummy materials. As a critical long-tail precision tool, it is the industry standard for reliable machining of 300-series stainless and heat-resistant alloys.

US735 PVD Grade
The US735 grade is Mitsubishi's premier PVD solution for stainless steel. It features a specialized coating that prevents welding between the tool and the workpiece. Its high toughness makes it significantly more resistant to breakage than CVD grades when facing interrupted turning conditions.
Positive Chipbreaker
The TCMT positive geometry combined with the US735 coating provides low cutting resistance. This prevents vibration and ensures smooth chip evacuation, which is critical for maintaining surface finish and tool life in difficult-to-cut alloys.
