Mitsubishi Materials | The Left-Hand Specialist for Stainless Semi-Finishing
The Mitsubishi TNMG160408L-ES US735 is a high-toughness Left-Hand (L) variant of the industry-standard TNMG series. Specifically engineered for stainless steel turning, the US735 grade utilizes a specialized CVD coating that excels in interrupted cuts. The ES chipbreaker is the master of semi-finishing, providing superior chip control and heat dissipation in gummy materials like SUS304 and SUS316.

US735 Grade Technology
The US735 grade is a specialized CVD carbide designed for P-M-K applications, specifically targeting M30-M40 stainless steel. It provides extreme resistance to built-up edge (BUE) and mechanical shocking, making it an elite long-tail precision tool for high-mix production.
ES Chipbreaker Design
The ES chipbreaker is Mitsubishi’s answer to precision machining in gummy alloys. Its high-rake edge reduces cutting force, while the specialized chip-pocket prevents bird-nesting in CNC machining environments, even at lower feed rates.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
