DCMT11T304 VP15TF
Miracle PVD Technology | Multi-Material Universal Grade | 55° Diamond
Superior Sharpness for Mixed-Metal Machining
VP15TF Grade (The Miracle PVD): Mitsubishi’s VP15TF is a premium PVD-coated micro-grain carbide. The proprietary "Miracle Coating" (Al-Ti-N) provides incredible adhesion and heat resistance. Unlike bulky CVD coatings, PVD allows the insert to maintain an ultra-sharp cutting edge, which is critical for reducing cutting forces and preventing "Built-Up Edge" (BUE) in gummy materials like stainless steel or low-carbon steel.
DCMT Geometry (Positive Rake): The 55-degree diamond profile is the world standard for precision profiling and internal boring. The 7-degree positive relief angle ensures clean shearing, which results in superior surface finishes and reduced vibration on slender components.
0.4mm Radius (Precision Precision): The "04" (1/64") nose radius is the ideal choice for finishing. It minimizes radial pressure, allowing for tight tolerances and excellent surface roughness ($Ra$) even on machines with lighter spindle rigidity.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T304 | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | DCMT32.51 | 3/8" | 5/32" | 0.0157" (1/64") |
Recommended Cutting Parameters
*VP15TF is designed for medium speeds. Always use high-pressure coolant for Stainless Steel.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 90 - 180 m/min | 0.08 - 0.20 mm/r | 0.30 - 1.50 mm |
| Alloy Steel (4140) | 120 - 260 m/min | 0.10 - 0.25 mm/r | 0.50 - 2.00 mm |
Compatible Tool Holders
Maximum versatility with 11-series SDJCR/L or SDUCR/L holders:

VP15TF (PVD Generalist): Best for finishing and light semi-finishing of stainless and steel. It provides the best surface finish due to the sharp edge.
US735 (CVD Specialist): If you are doing heavy interrupted cuts or roughing stainless steel, switch to US735. It is tougher and can handle higher impact than the VP15TF.

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.
