DCMT11T308-MV US735
High-Impact Stainless Specialist | US735 CVD Toughness | MV Geometry
Built for Maximum Durability in Gummy Materials
US735 Grade (The Tough CVD): The US735 grade is specifically developed for the **M-Class (Stainless Steel)**. It features a high-toughness substrate and a CVD coating designed to resist "Notch Wear" and "Thermal Fatigue." This makes it the premier choice for machining stainless steel with **interrupted cuts** (like cross-holes or splines) where other grades might chip or crack.
MV Chipbreaker (Versatile Medium): The MV (Medium-V) chipbreaker is designed for stability. In the 11T3 size, it provides aggressive chip control, preventing the long, stringy chips common in austenitic stainless steel from wrapping around the tool or workpiece.
0.8mm Nose Radius (Impact Strength): The "08" (1/32") radius is engineered for strength. It can withstand significantly higher feed rates and deeper cuts than 0.4mm versions, while also being more resistant to mechanical shock in heavy semi-finishing applications.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T308-MV | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | DCMT32.52-MV | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Machining Parameters
*US735 requires high volumes of coolant to prevent work-hardening of the stainless surface.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic (304/316) | 80 - 150 m/min | 0.10 - 0.30 mm/r | 0.40 - 2.50 mm |
| Duplex/Super Alloys | 40 - 90 m/min | 0.08 - 0.20 mm/r | 0.30 - 1.80 mm |

US735 (CVD Carbide): Your reliability choice. Use this for all stainless steels, interrupted cuts, and jobs where tool failure must be prevented at all costs.
NX2525 (Cermet): Only for final finishing on carbon steel. Never use Cermet on stainless steel, as the gummy material will cause massive built-up edge and shatter the tool.
