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.

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.
