Tungaloy TNMG160404-TM T9115 Turning Insert

High-Speed CVD Grade | TM Medium-Cutting Chipbreaker | Premium Steel Machining

What is the best carbide insert for high-speed steel turning?

The Tungaloy TNMG160404-TM T9115 is a high-performance, double-sided triangular carbide insert optimized for the P-group (Steel) machining spectrum. Utilizing Tungaloy’s advanced T9115 CVD coating technology, this insert provides exceptional wear resistance and plastic deformation resistance during high-velocity operations. The -TM chipbreaker is a versatile medium-cutting geometry that ensures stable chip evacuation across varied depths of cut. 100% Made in Japan, it is engineered for professional CNC shops requiring high productivity and consistent tool life.

T9115 CVD Grade

Specifically designed for steel. Features a thick Al2O3 layer for superior heat protection and a hard TiCN layer for crater wear resistance at high speeds.

TM Chipbreaker Geometry

The "General Purpose" leader for medium cutting. It balances cutting edge strength with lower cutting force to prevent vibration in long-workpiece turning.

Premium Surface Luster

The specialized coating treatment reduces friction between the chip and the rake face, resulting in a superior surface finish on the final part.

Feedback from Global Workshops

⭐⭐⭐⭐⭐ "High Speed Master" - James K., USA
"T9115 is incredibly stable at high RPMs. We cut our cycle times by 15% since switching from a generic P-grade."

⭐⭐⭐⭐⭐ "Original Packaging" - Markus D., Germany
"Authentic Tungaloy Japan stock. The -TM chipbreaker works well for general carbon steel shafts. Quick shipping to Munich."

⭐⭐⭐⭐ "Great for Mass Production" - Hiroshi S., Japan
"Consistent tool life. We run these on our Nakamura lathes for 24/7 production with very few offsets needed."

⭐⭐⭐⭐⭐ "Best Price for Original" - Carlos M., Mexico
"Beyond is a reliable B2B partner. These inserts are genuine and help us stay competitive in automotive part supply."

⭐⭐⭐⭐⭐ "Reliable TM Geometry" - Alistair M., UK
"No chip wrapping issues on 4140 steel. The 0.4mm radius gives a very clean finish for final dimensioning."

8. FAQ - CNC Machine Support

Q: Can I use T9115 for machining stainless steel?

A: While it can handle light stainless cuts, T9115 is optimized for Steel (P). For stainless, we recommend the T6130 grade which is specifically designed to handle heat and work-hardening.

Q: Is the 0.4mm corner radius strong enough for heavy roughing?

A: The 0.4mm radius is better for medium-to-finishing. For heavy roughing with scale or interrupted cuts, we recommend a 0.8mm or 1.2mm radius for better edge integrity.

Q: What is the difference between TM and TS chipbreakers?

A: -TM is a general-purpose medium-cutting geometry. -TS is a finishing chipbreaker with a sharper edge designed for lighter depths of cut and lower feed rates.

Tech Tip: CVD Coating for Steel

The **T9115 CVD grade** is engineered for high-temperature stability. In high-speed turning, the Al2O3 layer prevents heat from reaching the carbide substrate, preventing deformation. Maintain high Vc for optimal results. **Tungaloy Japan** - Global Tooling Excellence.

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?
