CNMG120408-MS VP15TF
Universal Miracle Grade | PVD VP15TF Coating | MS Chip Control Geometry
Engineered for High-Performance Machining
VP15TF Miracle Grade (The PVD Powerhouse): The VP15TF is Mitsubishi’s most versatile PVD-coated grade. It features a micro-grain carbide substrate with a specialized "Miracle" (Al-Ti-N) coating. This thin, smooth coating allows for a razor-sharp edge, which is critical for reducing cutting resistance and preventing Built-Up Edge (BUE) when machining gummy materials like 304/316 Stainless Steel.
MS Chipbreaker (Precision Control): The MS geometry is a sharp-edged chipbreaker designed for finishing to medium-duty cutting. It features a high rake angle that effectively shears the material, preventing the work-hardening often associated with austenitic stainless steels. It excels at breaking chips into small, manageable "6" shapes even at lower feed rates.
0.8mm (1/32") Universal Radius: The 08 radius provides the ideal balance of edge strength and surface finish quality. It is robust enough for light roughing while sharp enough to achieve high-precision Ra values in finishing passes.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120408-MS | 12.7 mm | 4.76 mm | 0.80 mm |
| Imperial | CNMG432-MS | 1/2" | 3/16" | 0.0315" (1/32") |
Precision Cutting Parameters
*The VP15TF grade performs best with high-pressure coolant to manage heat in the cutting zone.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.10 - 0.25 mm/r | 0.50 - 2.50 mm |
| Alloy Steel (4140/4340) | 140 - 220 m/min | 0.12 - 0.30 mm/r | 0.80 - 3.00 mm |

VP15TF vs. US735: Both are great for stainless, but VP15TF offers higher wear resistance for continuous turning. Use US735 if you are performing heavy interrupted cuts where impact toughness is more important than pure sharpness.
MS vs. MA Geometry: Choose MS when chip control is your main issue. The MS geometry breaks chips more aggressively than the MA version.

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.
