DCMT070204 US735
Stainless Specialist | Tough CVD Grade | 55° Diamond Geometry
The "Stainless Steel Workhorse"
US735 Grade (Impact-Resistant CVD): The US735 is Mitsubishi’s premier grade for austenitic and martensitic stainless steels. It features a thick, thermally stable TiCN+Al2O3 CVD coating. Unlike brittle finishing grades, US735 is optimized for shock resistance, making it the top choice for interrupted cuts or parts with pre-existing holes/keyways.
Positive DCMT Geometry: The 55-degree diamond shape with a 7° relief angle creates a sharp, positive cutting action. This "slices" through gummy materials like 304 and 316 stainless steel, preventing the built-up edge (BUE) that often leads to poor surface finish and sudden tool failure.
0.4mm Versatile Radius: The "04" (1/64") radius is the industry standard for general finishing. It provides a robust cutting edge that resists thermal cracking while being sharp enough to achieve high-precision Ra surface values.

US735 (CVD): Optimized for heat resistance and high toughness. Choose this for general stainless turning and interrupted cuts where the tool takes a beating.
VP15TF (PVD): A sharper edge. Choose this for very light finishing passes, small components, or when machining exotic heat-resistant alloys (Inconel/Titanium) at lower speeds.

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.
