Tungaloy LNMU0303ZER-ML AH130 Insert

TungForce-Rec Double-Sided 4-Edge | ML Sharp Chipbreaker | Made in Japan

What is the best milling insert for gummy stainless steel and titanium?

The Tungaloy LNMU0303ZER-ML AH130 is a specialized indexable milling insert engineered for light to medium-duty machining in difficult-to-cut materials. Featuring the advanced AH130 PVD coated grade, this insert offers exceptional resistance to thermal cracking and notch wear, making it the industry standard for 300-series stainless steel and titanium alloys. The ML chipbreaker is designed with a sharper rake angle to reduce cutting resistance and prevent work hardening in gummy materials. With its unique double-sided 4-edge structure, this Japan-made milling insert provides high cost-efficiency and superior surface finish Ra for precision CNC machining cycles.

Technical Specs: Metric vs. Imperial Units

ISO Parameter Metric Unit Imperial Designation
Cutting Edge Length 3.5 mm 0.138 inch
Insert Thickness 3.18 mm 1/8 inch
Inscribed Circle (IC) 6.35 mm 1/4 inch
Corner Radius 0.4 mm 0.0157 inch

Recommended Cutting Parameters (AH130 Grade)

  • Cutting Speed (Vc): 40 - 100 m/min (Titanium Alloys) | 60 - 150 m/min (Stainless Steel)
  • Feed per Tooth (fz): 0.10 - 0.25 mm/t (Optimized for ML breaker)
  • Max Depth of Cut (Ap): 0.5 - 0.8 mm (Ideal for light feed logic)

*Pro Tip: For machining titanium, use a generous supply of high-pressure coolant to manage heat. The AH130 grade is specifically formulated to resist the high thermal loads of aerospace machining.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Game Changer for 316 Stainless" - Stefan H., Germany
"The ML chipbreaker makes such a difference. We were struggling with built-up edge, but this insert stays clean and sharp."

⭐⭐⭐⭐⭐ "Top Choice for Titanium" - Takumi K., Japan
"Consistent tool life in Aerospace alloys. AH130 grade is very reliable for overnight CNC production."

⭐⭐⭐⭐ "Smooth Cutting Action" - James W., USA
"Low vibration and very low power consumption on our machine. The surface finish on the shoulder is excellent."

⭐⭐⭐⭐⭐ "Economic 4-Edges" - L. Bernard, France
"Having 4 edges on such a small insert is great for the budget. No quality trade-off either."

⭐⭐⭐⭐⭐ "Genuine Japanese Quality" - S. Gupta, Singapore
"Fast delivery and original Tungaloy parts. The precision is unmatched for small batch high-value parts."

Technical Tooling Q&A

Q: Is AH130 better than AH725 for stainless steel?

A: AH130 is superior for austenitic stainless steel and titanium due to its increased thermal resistance. AH725 is a better all-rounder for general steel and cast iron.

Q: What is the main benefit of the ML chipbreaker?

A: The ML is a 'Light Cut' geometry. It is sharper than the MJ breaker, which helps avoid work-hardening on the surface of stainless parts and reduces spindle load.

Q: Which cutters do I need for LNMU0303?

A: It is compatible with the Tungaloy TungForce-Rec series (EXLS or TXP holders). Always match the seat size for Series 03 inserts.

Expert Insight: AH130 Grade Logic

In high-performance milling, AH130 is a specialized PVD grade designed to handle the localized heat and high pressure of Superalloys (S) and Stainless (M). By using the ML breaker, you ensure the sharpest entry possible into the material, which is critical for maintaining tool life and tight tolerances in CNC machining.

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?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times.
