MITSUBISHI WNMG080412-MA VP15TF

Universal Medium Roughing Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080412-MA VP15TF is a premium, double-sided 80° trigon negative insert designed for universal CNC machining. Featuring the renowned VP15TF PVD Miracle Coating, this insert provides exceptional versatility across steel, stainless steel, and heat-resistant alloys. Engineered in Japan, the robust 1.2mm corner radius combined with the MA chipbreaker makes it a high-performance choice for medium-to-heavy CNC turning where edge strength and surface finish are critical.

VP15TF PVD Miracle Coating: The All-Rounder

The VP15TF grade is Mitsubishi's legendary indexable carbide insert material. Unlike thicker CVD coatings, this PVD (Physical Vapor Deposition) technology allows for a sharper cutting edge, which is vital for reducing cutting pressure in CNC machining. It provides a "miracle" balance—tough enough to handle light interruptions and hard enough to resist abrasive wear in carbon steel, alloy steel, and stainless steel.

MA Chipbreaker Geometry

The MA chipbreaker is an all-purpose medium-range geometry. It provides an excellent land-angle balance that reinforces the edge against chipping while ensuring smooth chip control. This prevents long-stringy chips from scratching your workpiece or damaging the CNC turning tool holder, even when working with "gummy" materials like stainless steel.

Recommended Cutting Parameters

Optimized for Universal Application (P, M, K Class):

  • Cutting Speed (Vc): 90 - 200 m/min (295 - 655 SFM)
  • Feed Rate (f): 0.20 - 0.50 mm/rev (0.008 - 0.020 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: The 1.2mm radius is perfect for heavy medium cutting with higher feed rates.*

Technical Q&A

Q: Can I use VP15TF for Cast Iron?

A: Yes, VP15TF is a universal grade that performs well in cast iron. However, for high-speed mass production of cast iron, MC5005 is specialized for that purpose.

Q: Why use the 1.2mm radius (12) instead of 0.8mm (08)?

A: The 1.2mm radius provides a stronger edge and allows for higher feed rates, making it ideal for roughing or heavy medium cutting.

Q: Does this insert have 6 cutting edges?

A: Yes. Being a negative trigon (W-shape), it provides 3 edges per side for a total of 6 usable edges.

Expert Choice Tip: VP15TF vs VP20RT

For General Purpose Steel and Stainless, choose VP15TF. For Heat Resistant Super Alloys or very difficult stainless jobs, the VP20RT grade offers even higher thermal resistance.
