Tungaloy LMMU160916PNER-MJ AH725 Insert

TungForce-Rec Double-Sided Milling | MJ Chipbreaker | Made in Japan

What is the best double-sided milling insert for heavy shoulder milling?

The Tungaloy LMMU160916PNER-MJ AH725 is a high-efficiency indexable milling insert from the renowned TungForce-Rec line. Designed with a robust double-sided structure, it offers 4 economical cutting edges while maintaining the rigidity of a single-sided insert. The AH725 PVD coated grade is a versatile powerhouse, combining a tough carbide substrate with a multilayered (Ti, Al)N coating, making it exceptional for machining general steels and stainless steels. The MJ chipbreaker is specifically tailored for medium-duty cutting, providing an ideal balance between sharpness and edge strength in CNC milling operations. This Japan-made milling insert is the professional choice for achieving high metal removal rates (MRR) with superior surface finish.

Technical Specs: Metric vs. Imperial Conversion

ISO Parameter Metric Designation Imperial Designation
Cutting Edge Length 16.0 mm 0.630 inch
Insert Thickness 9.53 mm 3/8 inch
Corner Radius (RE) 1.6 mm 1/16 inch
Wiper Width (BS) 1.2 mm 0.047 inch

Recommended Cutting Parameters (AH725 Grade)

  • Cutting Speed (Vc): 100 - 250 m/min (Carbon/Alloy Steel)
  • Feed per Tooth (fz): 0.10 - 0.25 mm/t (Optimized for MJ Chipbreaker)
  • Machining Type: Shouldering, Slotting, and Ramping.

*Pro Tip: Use AH725 for wet or dry cutting. For maximum tool life in stainless steel, internal coolant is highly recommended.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Economic and Tough" - Dieter B., Germany
"4 edges per insert makes this very cost-effective. The AH725 grade handles our 4140 steel blocks perfectly."

⭐⭐⭐⭐⭐ "Great for Stainless" - Kenji Y., Japan
"I use these for 304 stainless milling. The MJ breaker handles chips better than any competitors I've tried."

⭐⭐⭐⭐ "Heavy Removal Rates" - Mark S., USA
"We pushed the feed rate on a large fixture job. The inserts didn't chip even with heavy interrupted cuts."

⭐⭐⭐⭐⭐ "Perfect Surface Finish" - Carlos M., Mexico
"The 1.6mm radius gives a very strong corner and a surprisingly smooth wall finish on our shoulder mill."

⭐⭐⭐⭐⭐ "Fast Delivery & Genuine" - William R., UK
"Authentic Tungaloy stock. The PVD coating AH725 is a lifesaver for our general machine shop."

Technical Tooling Q&A

Q: Can I use this for high-speed milling in aluminum?

A: AH725 is a PVD coated carbide designed for steel and stainless. For aluminum, we recommend an uncoated grade like KS05F for better chip flow.

Q: Is the LMMU16 insert compatible with standard 90-degree holders?

A: Yes, it is designed for the TungForce-Rec series of shoulder mills to achieve precise 90-degree shoulders.

Q: What makes the MJ chipbreaker different?

A: The MJ geometry is a general-purpose breaker that combines a sharp rake angle with a stable land to prevent edge chipping during medium-range milling.

Expert Tooling Tip: Grade Optimization

In high-performance milling, AH725 is the "Swiss Army Knife" of grades. It offers superior resistance to thermal cracking. For long-running production in stable steel cutting, you might compare this with CVD grades, but for versatile CNC shops, AH725 remains the most reliable performer.

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.
