DCMT070202 US735
Stainless Steel Specialist | US735 Tough CVD | Precision 55° Diamond
Built for Gummy & Tough Materials
US735 Grade (CVD Coated Toughness): The US735 is Mitsubishi’s premier grade for stainless steel turning. It features a specialized thick TiCN+Al2O3 coating that provides high heat resistance, while the substrate is optimized for interrupted cuts. It excels in preventing the built-up edge (BUE) and chipping commonly found when machining 300-series stainless steel.
DCMT Geometry (Anti-Vibration Design): The 55-degree diamond shape provides high versatility for both facing and longitudinal turning. As a positive rake insert, it peels material away with minimal force, which is critical for maintaining the surface integrity of heat-sensitive alloys.
0.2mm Nose Radius: The "02" radius is designed for finishing passes where accuracy is paramount. Because of the small radius, cutting resistance is shifted axially rather than radially, significantly reducing "chatter" in small boring bars and long, slender workpieces.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT070202 | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCMT21.50.5 | 1/4" | 3/32" | 0.0078" |
Recommended Cutting Parameters
*The US735 grade thrives in low to medium speed ranges where high toughness is required.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 80 - 160 m/min | 0.03 - 0.12 mm/r | 0.10 - 1.00 mm |
| High-Temp Alloys (Inconel) | 25 - 60 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.80 mm |

Shop 07 Series HoldersPro-Tip: US735 vs. VP15TF
US735 (CVD): Your first choice for heavy-duty stainless machining and interrupted cuts. It has superior impact resistance.
VP15TF (PVD): Better suited for finishing very small parts or when a razor-sharp edge is needed for exotic materials that work-harden easily.

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.
