CNMG120408-MA VP15TF
The Miracle Multi-Tasker | PVD VP15TF Grade | MA Versatile Geometry
Superior PVD Performance for Mixed Production
VP15TF Miracle Grade (The PVD Powerhouse): The VP15TF grade features a ultra-fine micro-grain carbide substrate coated with Mitsubishi's "Miracle" PVD layer (Al-Ti-N based). This coating provides an exceptional balance of wear resistance and toughness. Because it is a PVD process, the cutting edge remains significantly sharper than CVD-coated equivalents, making it the "gold standard" for Stainless Steel (M-class) and General Steel (P-class).
MA Chipbreaker (Medium-Duty Reliability): The MA chipbreaker is designed for a broad range of applications. It features a specialized rake angle that promotes smooth chip flow while maintaining edge integrity. Whether you are performing continuous turning or light interrupted cuts, the MA geometry ensures efficient metal removal and prevents chip nesting.
0.8mm (1/32") Universal Radius: The 0.8mm corner radius is the most widely used size in modern machining. It is robust enough for medium roughing passes while maintaining the precision required to produce excellent surface finishes (Ra) in the final pass.

Recommended Cutting Parameters
*VP15TF performs exceptionally well with coolant. Adjust speeds based on the hardness of your specific workpiece.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 200 m/min | 0.10 - 0.35 mm/r | 0.50 - 4.00 mm |
| Alloy Steel (4140/4340) | 140 - 240 m/min | 0.12 - 0.40 mm/r | 0.80 - 4.50 mm |

Shop DCLNR 12 HoldersPro-Tip: When to choose VP15TF?
VP15TF vs. US735: While both are for stainless steel, VP15TF is more universal. If you are experiencing vibration or chipping in stainless, VP15TF’s tougher substrate often solves the problem.
VP15TF vs. UE6110: If you are machining continuous, clean steel at very high speeds, stay with UE6110 (CVD). If you have a mix of steel and stainless parts in your queue, use VP15TF to reduce tool changes.

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.
