MITSUBISHI WNMG080408 UC5115

Professional Cast Iron Machining | Superior Wear Resistance | Made in Japan

Product Overview

The Mitsubishi WNMG080408 UC5115 is a high-durability double-sided 80° trigon insert specifically engineered for Cast Iron turning (K-Class). Equipped with the industry-leading UC5115 CVD coating, this insert is built to withstand the highly abrasive nature of gray and ductile cast iron. With a robust 0.8mm corner radius, it provides excellent edge strength for medium cutting to light roughing. These indexable carbide inserts are essential for CNC machining facilities requiring long tool life and consistent precision machining in heavy-duty industrial casting environments.

Grade: UC5115 (The Cast Iron Master)

The UC5115 grade is Mitsubishi's premier solution for Cast Iron (K-Class) turning. Cast iron machining presents unique challenges such as abrasive wear and rapid heat generation. UC5115 utilizes a specialized CVD coating with high thermal stability and a tough carbide substrate to resist flank wear and thermal cracking. This ensures your CNC lathe maintains strict tolerances during long production runs in gray or nodular iron.

Enhanced 0.8mm Radius Strength

The 0.8mm corner radius provides a larger contact area, increasing edge strength and heat dissipation. This makes the WNMG080408 highly effective for medium cutting applications where higher feed rates are required. In CNC machining, this geometry helps achieve a stable balance between metal removal rate and surface quality.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 160 - 350 m/min (525 - 1150 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: For high-speed gray iron turning, stay at the upper end of Vc for maximum productivity. For ductile iron with skin, reduce speed for the first pass.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Best for Cast Iron" - James R., USA
"We turn massive ductile iron pulleys and UC5115 is the only grade that holds up. The tool life is incredible compared to standard grades."

⭐⭐⭐⭐⭐ "Stable and Consistent" - Lars H., Germany
"Consistent results across every batch. Mitsubishi Japan always delivers the highest quality. No surprises on the machine."

⭐⭐⭐⭐ "Great for Roughing" - Yuki T., Japan
"The 0.8mm radius is very robust. We use it for medium roughing on gray iron castings with great success."

⭐⭐⭐⭐⭐ "Unbeatable Value" - Mark S., UK
"6 usable edges per insert makes the WNMG trigon a cost-saver. Combined with the UC5115 durability, it's a win."

⭐⭐⭐⭐⭐ "Original and Authentic" - Jan V., Belgium
"Received original Mitsubishi packaging. The high-speed performance is exactly as described. Very happy with the purchase."

Technical Q&A

Q: Can I use UC5115 for Steel parts?

A: It is primarily designed for Cast Iron (K-Class). For steel applications, we strongly recommend MC6025 or UE6020 for better performance.

Q: Why is 0.8mm radius better for iron than 0.4mm?

A: Cast iron can be very abrasive. The 0.8mm radius offers a stronger edge that resists chipping and manages heat better during medium-to-rough cutting.

Q: How many cutting edges are on this insert?

A: WNMG is a double-sided trigon, giving you 6 usable cutting edges, making it significantly more economical than 4-edge inserts.

Expert Machining Tip: UC5115 vs. UC5105

Use UC5115 for general-purpose cast iron turning and light interruptions. For Ultra-High-Speed continuous turning on gray iron only, UC5105 provides maximum wear resistance.
