DCMT070202-MV US735
Stainless Steel Specialist | Tough CVD Coating | 0.2mm Precision Radius
Engineered for Difficult-to-Cut Materials
US735 Grade (Tough CVD): The US735 is Mitsubishi's premier grade for Stainless Steel. It features a specialized CVD coating designed to prevent thermal cracking and notch wear. This grade is highly recommended for "unstable" conditions, such as interrupted cuts or when the workpiece material is particularly gummy (e.g., 304, 316, or Duplex Stainless).
MV Chipbreaker (Medium-V Finishing): The MV geometry is a versatile finishing-to-medium chipbreaker. It provides excellent chip control across a range of depths ($Ap$), effectively breaking long stringy chips that are common when machining stainless steel, thereby protecting your workpiece and the tool holder.
0.2mm Nose Radius: The "02" radius is designed for ultra-precision. It generates minimal radial cutting pressure, making it the perfect choice for thin-walled parts, small diameters, or boring applications where vibration must be strictly controlled.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT070202-MV | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCMT21.50.5-MV | 1/4" | 3/32" | 0.0078" (1/128") |
Recommended Machining Parameters
*US735 is optimized for toughness. Use lower speeds compared to PVD grades in dry conditions, or flood coolant for max life.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| 304/316 Stainless Steel | 80 - 150 m/min | 0.04 - 0.12 mm/r | 0.15 - 1.20 mm |
| Duplex / Tough Alloys | 60 - 120 m/min | 0.03 - 0.10 mm/r | 0.15 - 1.00 mm |

Shop 07 Series HoldersPro-Tip: US735 vs. VP15TF
US735 (CVD): Choose this for stability. If your machine isn't perfectly rigid or if you have interrupted cuts (like keyways), the US735 is much more resistant to chipping.
VP15TF (PVD): Switch to VP15TF for continuous finishing at higher speeds on small parts where a razor-sharp edge is more critical than raw toughness.

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.
