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

How do I choose the correct specification?

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.

How can I check compatibility with my existing setup?

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.

What quantity and price unit am I 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.

How should I choose cutting parameters?

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.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?
