MITSUBISHI WNMG080412 VP15TF

High-Feed Miracle PVD Grade | 1.2mm Radius for Maximum Toughness | Made in Japan

Product Overview

The Mitsubishi WNMG080412 VP15TF is a heavy-duty, double-sided 80° trigon insert designed for ultimate reliability in CNC turning. Featuring the legendary VP15TF Miracle PVD coating, this insert excels in difficult-to-machine materials, including Stainless Steel, heat-resistant alloys, and carbon steels. With a robust 1.2mm corner radius, it is specifically built to handle high feed rates and interrupted cuts where edge strength is critical. As an indexable carbide insert, it offers high thermal stability and wear resistance, ensuring precision machining even in the most demanding shop environments.

Material: VP15TF (The Universal Miracle)

The VP15TF Miracle PVD coating is Mitsubishi's benchmark for versatility. It provides a unique combination of high hardness and extreme toughness. This grade prevents notch wear and provides superior resistance to thermal cracking, making it the primary choice for stainless steel turning and alloy steel applications where chip control and surface finish are paramount. The thin PVD layer maintains a sharp cutting edge, reducing vibration and cutting pressure on the machine spindle.

Edge Strength: 1.2mm Corner Radius

The 1.2mm corner radius (R1.2) provides a larger contact area, which significantly increases the heat dissipation capacity of the tool tip. This geometry is ideal for rough turning and high-feed passes, preventing premature edge failure when dealing with tough casting skins or scale on CNC turning parts.

Recommended Cutting Parameters

Optimized for Universal Machining (P, M, K, S):

  • Cutting Speed (Vc): 90 - 240 m/min (300 - 790 SFM)
  • Feed Rate (f): 0.20 - 0.55 mm/rev (0.008 - 0.022 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: For heavy feed applications, ensure your machine setup has high rigidity to take full advantage of the R1.2 corner radius.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Heavy Duty Workhorse" - Chris B., USA
"The 1.2mm radius on VP15TF is my secret weapon for interrupted cuts in stainless. These inserts just keep going."

⭐⭐⭐⭐⭐ "Best Versatility" - Marco V., Italy
"We use these for alloy steel and 316 stainless. Very stable tool life and great precision. Authentic Japanese quality."

⭐⭐⭐⭐ "6 Edges Value" - Taro S., Japan
"Switching from CNMG to WNMG was a smart move. Getting 6 edges in the Miracle grade really saves on tool costs."

⭐⭐⭐⭐⭐ "Original & Tough" - Liam F., Australia
"Packaged well and 100% original. The VP15TF grade is extremely tough for high-feed roughing."

⭐⭐⭐⭐⭐ "Reliable for Small Shops" - Sacha D., France
"Excellent multi-material performance. I don't have to change inserts when I switch from mild steel to stainless."

Technical Q&A

Q: Is VP15TF better than CVD grades for stainless?

A: For general stainless turning, yes. The PVD coating is thinner and provides a sharper edge, which prevents the material from welding to the tip (BUE).

Q: When should I use the 1.2mm radius?

A: Use the 1.2mm radius for roughing, high-feed passes, or when you are dealing with interrupted cuts where a smaller radius might chip.

Q: Does the trigon shape affect finish quality?

A: WNMG trigon inserts offer the same 80° tip angle as CNMG diamond inserts, providing the same high surface finish while offering 6 usable cutting edges.

Expert Machining Tip: VP15TF vs. VP05RT

Choose VP15TF for maximum versatility and toughness across various materials. For High-Speed turning in heat-resistant super alloys (Titanium/Inconel), consider the VP05RT grade for specialized performance.
