Tungaloy TNMG160404-TM AH725 Turning Insert

High-Performance PVD Grade | TM Medium-Cutting Geometry | Made in Japan

Which insert is best for general purpose steel and stainless turning?

The Tungaloy TNMG160404-TM AH725 is a versatile, high-rigidity turning insert designed for the demands of modern CNC shops. Featuring the legendary AH725 PVD coated grade, this insert excels in both carbon steels and difficult-to-cut stainless steels. The -TM chipbreaker is the industrial standard for medium-duty cutting, providing a perfect balance between chip control and edge strength. Whether you are performing continuous turning or light interrupted cuts, the TNMG 160404-TM provides stable tool life and superior surface integrity. 100% Made in Japan by Tungaloy Corporation.

AH725 PVD Grade

A premium PVD coating with a tough carbide substrate. Highly resistant to chipping and thermal shock, making it ideal for various materials and machining conditions.

TM Medium Geometry

Specifically engineered for medium cutting depths. It provides excellent chip evacuation across a wide range of feed rates, reducing machine downtime.

Double-Sided Design

Features 6 usable cutting edges per triangular insert, significantly lowering your cost-per-edge in high-volume production environments.

Customer Reviews from Professional Workshops

⭐⭐⭐⭐⭐ "Workhorse Grade" - James K., USA
"AH725 is a beast. We switch between 1045 steel and 304 stainless without changing the insert. The TM chipbreaker handles everything."

⭐⭐⭐⭐⭐ "Original Tungaloy" - Markus D., Germany
"Received in factory sealed boxes. The quality is noticeably better than generic alternatives. Best price/performance ratio."

⭐⭐⭐⭐ "Great for Interrupted Cuts" - Hiroshi S., Japan
"Consistent tool life even with light interruptions. The edge stays sharp for a long time. Very reliable supplier."

⭐⭐⭐⭐⭐ "B2B Support is Top" - Carlos M., Mexico
"Beyond helped us with the cutting parameters. The inserts work perfectly on our Mazak lathe. Will buy again."

⭐⭐⭐⭐⭐ "Superior Finish" - Alistair M., UK
"Excellent surface finish on our stainless components. AH725 really resists building up edge better than others."

8. FAQ - Machine Shop Technical Support

Q: Can I use AH725 for heavy roughing?

A: AH725 is a tough PVD grade, but the -TM geometry is optimized for medium cutting. For heavy roughing, we recommend the -TH or -TH chipbreakers with a larger corner radius.

Q: Is this insert compatible with all TNMG tool holders?

A: Yes, as long as the tool holder is designed for the 16 size (ISO) or 33 size (ANSI), the TNMG160404-TM will fit perfectly regardless of brand.

Q: What is the benefit of the TM chipbreaker?

A: The -TM (Medium) chipbreaker is designed for general purpose machining. It provides a wide application range for depths of cut and feed rates, making it very versatile for different jobs.

Tech Tip: PVD vs CVD Coatings

The **AH725 PVD grade** provides a sharper edge and higher toughness compared to CVD coatings. This makes it superior for stainless steel and machining small diameters where heat and edge integrity are critical. **Tungaloy Japan** - Excellence in Tooling Technology.

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.
