DCMT11T302-MV US735
Precision Finishing | US735 CVD Toughness | Anti-Vibration 0.2mm Radius
Optimized for High-Heat & Low-Pressure Cutting
US735 Grade (The Stainless Specialist): The US735 is a CVD-coated carbide specifically engineered for the M-class (Stainless Steel) group. It utilizes a high-toughness substrate that absorbs the mechanical shocks of interrupted cuts, paired with a coating that resists "built-up edge" (BUE) and thermal fatigue common in 304 and 316 stainless.
MV Chipbreaker (Stable Precision): The MV (Medium-V) geometry is a versatile performer. In this 11T3 size, it provides excellent chip evacuation for finishing passes. It forces chips to curl and break even at shallow depths, preventing "bird-nesting" that can ruin a precision surface finish.
0.2mm Radius (Vibration Control): The sharp "02" nose radius is critical for thin-walled parts. By reducing radial cutting forces, it prevents the workpiece from "pushing away" or vibrating, ensuring tight tolerances and a smooth $Ra$ value.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T302-MV | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCMT32.50.5-MV | 3/8" | 5/32" | 0.0078" (1/128") |
Recommended Machining Parameters
*US735 excels with coolant. For thin parts, use the lower end of the feed range.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 80 - 150 m/min | 0.04 - 0.12 mm/r | 0.15 - 1.00 mm |
| Martensitic Stainless (420/440C) | 100 - 170 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.20 mm |

US735 (CVD): Optimized for toughness. If you are experiencing edge chipping or thermal cracking in stainless steel, US735 is the most stable choice.
VP15TF (PVD): Switch to VP15TF if you are doing very light, high-speed finishing on small parts where the sharpest possible edge is required to minimize heat generation.

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.
