Tungaloy ONMU0705ANPN-MJ AH725 Insert

DoOcto Double-Sided 16-Edge Milling | MJ Chipbreaker | Made in Japan

What is the most economical face milling insert for steel and stainless?

The Tungaloy ONMU0705ANPN-MJ AH725 is a high-productivity indexable milling insert from the elite DoOcto series. This insert features a unique octagonal double-sided design that provides an incredible 16 cutting edges per insert, making it one of the most cost-effective solutions in the industry. The AH725 PVD coated grade offers a perfect synergy of a tough carbide substrate and a wear-resistant coating, excelling in general steel and stainless steel machining. With the MJ medium-duty chipbreaker, it ensures low cutting force and excellent chip control. As a genuine Japan-made face milling insert, it is engineered to deliver high metal removal rates and superior surface finish Ra in rigorous CNC machining environments.

Technical Specs: Metric vs. Imperial Units

ISO Parameter Metric Unit Imperial Designation
Inscribed Circle (IC) 15.875 mm 5/8 inch
Insert Thickness (S) 5.45 mm 0.215 inch
Wiper Width (BS) 2.0 mm 0.0787 inch
Model Number ONMU0705 ONMU 544

Recommended Cutting Parameters (AH725 Grade)

  • Cutting Speed (Vc): 100 - 250 m/min (Carbon & Alloy Steel)
  • Feed per Tooth (fz): 0.15 - 0.40 mm/t (Optimized for MJ breaker)
  • Max Depth of Cut (Ap): 3.5 mm (Ensure rigid setup)

*Pro Tip: For heavy face milling, ensure the cutter body is fully supported. The 16-edge design allows for extreme cost-per-edge reduction. Dry machining is often preferred for AH725 to maximize thermal resistance.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Unbeatable Cost Efficiency" - Hans R., Germany
"16 edges on one insert is incredible. We halved our tooling costs for surface milling 1045 steel blocks."

⭐⭐⭐⭐⭐ "Stable and Reliable" - Y. Tanaka, Japan
"Very stable cutting even at 3mm depth of cut. AH725 remains the most versatile grade for our job shop."

⭐⭐⭐⭐ "Great Wall Finish" - Mike D., USA
"The octagonal shape gives a much better finish than square inserts at high feed. Minimal burr on stainless."

⭐⭐⭐⭐⭐ "Long Lasting AH725" - Alessandro V., Italy
"We use these for roughing and finishing. The PVD coating is very tough against thermal shock."

⭐⭐⭐⭐⭐ "Authentic Product" - S. Lee, Singapore
"Fast shipping and genuine Tungaloy inserts. Precision is consistent across all 16 edges."

Technical Tooling Q&A

Q: Can I use ONMU0705 for 90-degree shoulder milling?

A: No, the octagonal shape is designed specifically for 45-degree lead angle face milling. For 90-degree shoulders, please use the TungForce-Rec series.

Q: What is the benefit of a 45-degree lead angle?

A: It thins the chips, allowing for higher feed rates and directing cutting forces toward the spindle, which increases stability and tool life.

Q: How do I know when to rotate the insert?

A: Each edge is numbered on the insert. Simply rotate to the next number when you notice flank wear or a drop in surface finish quality.

Expert Insight: 16-Edge Value Proposition

In CNC face milling, the ONMU0705 with AH725 grade provides a massive advantage in throughput. By utilizing 16 edges, shops can maintain longer unattended runs. The 45-degree angle reduces vibration, protecting your machine spindle while delivering precision machining results on every pass.

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.
