MITSUBISHI WNMA080412 UC5115

Heavy-Duty Cast Iron Specialist | Advanced CVD Wear Resistance

Product Overview

The Mitsubishi WNMA080412 UC5115 is a high-performance, double-sided 80° trigon-shaped negative insert engineered specifically for the high-speed machining of cast iron. Featuring a robust 1.2mm nose radius and the specialized UC5115 CVD coating, this insert excels in abrasive environments where heat and wear resistance are paramount. It is the premier choice for CNC professionals machining gray cast iron (GG) and ductile iron (GGG) in heavy turning and high-productivity applications.

Material & Coating: UC5115 Grade

The UC5115 grade is Mitsubishi’s authoritative solution for cast iron turning. It utilizes a thick Alumina (Al2O3) CVD coating that provides an incredible thermal barrier against the heat generated during dry machining. This allows for significantly higher cutting speeds (Vc) while maintaining edge sharpess and resisting abrasive wear.

WNMA Flat Top Geometry

The WNMA (Flat top) geometry is specifically designed for materials like cast iron that produce short, brittle chips. Because it lacks a chipbreaker, the cutting edge is structurally stronger and more resistant to chipping during heavy-duty roughing and continuous cutting. The large 1.2mm radius ensures superior edge strength for heavy feed rates.

Recommended Cutting Parameters

Optimized for Cast Iron (Gray & Ductile):

  • Cutting Speed (Vc): 150 - 400 m/min (490 - 1310 SFM)
  • Feed Rate (f): 0.20 - 0.55 mm/rev (0.008 - 0.022 ipr)
  • Depth of Cut (ap): 1.0 - 5.0 mm

*Note: Running at higher speeds helps activate the CVD coating's thermal protective properties.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Workhorse for Cast Iron" - James H., USA
"We've been machining gray iron housings for years. The WNMA 1.2mm radius is a beast. The UC5115 coating stays intact even when the parts get hot. Highly recommend."

⭐⭐⭐⭐⭐ "Consistent Quality" - Dieter W., Germany
"Authentic Mitsubishi inserts. Tool life is very predictable, which is essential for our automated CNC lines. Fast shipping as well."

⭐⭐⭐⭐ "Great for Heavy Cuts" - Tanaka M., Japan
"The 1.2mm radius allows for heavy feeds. Very stable machining and no chipping on the ductile iron castings."

⭐⭐⭐⭐⭐ "Reliable Tooling" - Liam G., Australia
"Best price for genuine UC5115. These last much longer than the generic inserts we tried previously."

⭐⭐⭐⭐⭐ "Solid Performance" - Luca V., Italy
"High-speed turning on brake rotors is easy with these. Clean cuts and the coating doesn't peel."

Technical Q&A

Q: Can I use WNMA080412 on steel?

A: It is not recommended. WNMA (Flat Top) has no chipbreaker. Steel produces long ribbons that will wrap around the tool without a chipbreaker. Use WNMG for steel.

Q: What makes UC5115 better than general carbide?

A: It is specifically optimized for abrasive wear. Cast iron contains sand and hard inclusions that eat regular carbide; UC5115's CVD coating is designed to handle this.

Q: How many cutting edges are available?

A: This is a double-sided negative insert, giving you a total of 6 cutting edges.

Material Choice Tip: UC5115 vs. MC5015

For General Cast Iron Turning, UC5115 is the industry standard. If you are doing extremely high-speed, continuous finishing on gray iron, consider MC5015 for even higher wear resistance, but UC5115 is the superior all-rounder.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?
