CCMT09T302 US735
Stainless Steel Precision Specialist | PVD Coated | 0.2mm Radius
Material Science & Edge Sharpness
US735 Grade (PVD Toughness): Specifically engineered for ISO M (Stainless Steel) and ISO S (Heat-Resistant Alloys). Unlike CVD coatings which can be rounded, the US735 PVD coating maintains a razor-sharp edge. This is crucial for stainless steel to prevent the material from "smearing" or work-hardening. The substrate is a high-toughness carbide that resists notch wear and thermal cracking.
0.2mm Precision Radius (Low-Force Geometry): The 02 radius is designed to minimize radial cutting forces. It is the primary choice for precision finishing on long, slender workpieces or deep internal boring where chatter (vibration) is a constant risk.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T302 | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | CCMT32.50.5 | 0.375" (3/8") | 0.156" (5/32") | 0.0079" |
Recommended Cutting Parameters
*The 0.2mm radius is sensitive to high feeds. Ensure your feed rate does not exceed 0.10 mm/r to avoid tip breakage.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless (304/316) | 80 - 160 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.60 mm |
| Titanium Alloys | 40 - 80 m/min | 0.03 - 0.08 mm/r | 0.10 - 0.40 mm |

US735 (PVD): The Stainless Steel Master. It features a tougher coating adhesion specifically for gummy materials and high-temp alloys. Use this when your primary goal is tool life consistency in dedicated stainless production.
VP15TF (PVD): The All-Rounder. If your shop switches between carbon steel and stainless steel on the same machine frequently, VP15TF is more versatile across both ISO P and ISO M materials.

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.
