Mitsubishi VNMG160408-MA US735
High-Toughness CVD Grade for Interrupted Stainless Steel Machining
The Mitsubishi VNMG160408-MA US735 is a premium 35° rhombic negative-type carbide turning insert designed for maximum reliability. Engineered specifically for stainless steel turning, the US735 grade excels in interrupted cutting and unstable machining conditions. This VNMG 332-MA ANSI equivalent is a staple for CNC lathe operations where thermal cracking and chipping resistance are paramount.

- ANSI (Imperial): VNMG 332-MA
Advanced Material & Geometry
US735 Tough CVD Grade: This grade is Mitsubishi’s specialized CVD coated carbide for heavy-duty stainless steel turning. It features a high-toughness substrate paired with a coating that resists thermal shock, preventing the "cracking" often seen in wet, interrupted stainless cutting.
MA Chipbreaker: The MA breaker is the versatile "all-rounder" for medium-range cutting. It provides stable chip control across varied feed rates, ensuring a high surface finish while reducing the risk of chip entanglement on the tool holder.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 60 - 150 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
| Mild Steel (Roughing) | 80 - 180 m/min | 0.20 - 0.50 mm/rev | 1.0 - 3.5 mm |

US735 is your "Problem Solver" for interrupted cuts in stainless. For continuous, high-speed turning of stainless steel, we recommend VP15TF (PVD) for sharper edges. If you are machining carbon steel in stable conditions, the UE6110 or UE6020 grades will provide superior wear resistance at higher RPMs.

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.
