Tungaloy DNMG150408-TM T9115 Turning Insert

High-Speed Steel Machining | Premium T9115 CVD Grade | Made in Japan

What is the most efficient insert for high-speed semi-finishing of steel?

The Tungaloy DNMG150408-TM T9115 is a premium CVD coated carbide turning insert designed specifically for the high-efficiency machining of carbon and alloy steels. Utilizing the cutting-edge T9115 grade, this insert features a specialized thick Al2O3 (alumina) layer that provides an incredible thermal barrier, making it ideal for continuous, high-speed cutting where heat resistance is critical. The -TM chipbreaker is a versatile semi-finishing geometry that balances edge sharpness with robust strength. With a 0.8mm corner radius, this Japan-made indexable turning tool provides superior edge durability and excellent surface finish. For professional CNC machining shops, this insert is the go-to solution for maximizing tool life and reducing cycle times. By choosing this long-tail keywords optimized product, you are investing in Tungaloy's world-renowned precision and performance.

Why is the T9115 grade superior for high-speed steel turning?

The T9115 Grade represents the pinnacle of Tungaloy’s CVD coating technology. In precision machining, heat generation is the primary cause of tool failure. T9115 addresses this with "PremiumTec" technology, creating a smoother coating surface that reduces friction and prevents chips from welding to the edge. The -TM chipbreaker features a balanced rake angle that lowers cutting forces while maintaining chip breaking efficiency across various depths. For CNC machining of large steel workpieces, the 15mm edge length and 0.8mm radius of this indexable turning tool provide the stability required for aggressive feed rates and heavy material removal.

Recommended Cutting Parameters (T9115)

  • Cutting Speed (Vc): 150 - 350 m/min (Recommended for Carbon/Alloy Steel)
  • Feed Rate (f): 0.15 - 0.50 mm/rev
  • Depth of Cut (ap): 0.8 - 4.5 mm

*Tip: T9115 is optimized for continuous cutting. For interrupted cuts, ensure high-pressure coolant is applied to the cutting zone.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Extreme Tool Life" - Mark T., USA
"Switched to DNMG150408-TM T9115 for our 4140 shafts. We increased the speed by 20% and the tool life actually improved. Japan quality is unbeatable."

⭐⭐⭐⭐⭐ "Perfect Chip Control" - Dieter S., Germany
"The -TM breaker is very stable. No bird-nesting even at high speeds. This cVD coated carbide is worth every penny for production runs."

⭐⭐⭐⭐ "Very Stable" - Kenji O., Japan
"Consistent performance in automated lathes. T9115 handles the heat much better than other brands we've tested in alloy steel."

⭐⭐⭐⭐⭐ "Great for Mass Production" - Luca B., Italy
"Reduced our machine downtime significantly. The 0.8mm radius is very strong. Exceptional indexable turning tool."

⭐⭐⭐⭐⭐ "Fast Shipping & Genuine" - S. Richards, UK
"Original Tungaloy stock. Fast delivery. These inserts are the backbone of our steel turning department."

Technical Tooling Q&A

Q: Can I use T9115 for stainless steel?

A: T9115 is optimized for steel. For stainless, Tungaloy AH series or PVD grades are recommended to prevent work hardening and adhesion.

Q: What is the benefit of the -TM chipbreaker?

A: It is a semi-finishing breaker that works across a broad range of applications, providing excellent chip evacuation and reducing edge buildup.

Q: Which holder fits the DNMG1504 size?

A: It fits standard ISO holders like DDJNR/L 2525M15 or PDJNR/L 2020K15 using the 15mm (4xx) seat size.

Expert Tip: Maximizing CVD Efficiency

In precision machining, CVD Coated Carbide (T9115) thrives at high surface speeds. Unlike PVD, the thick alumina layer requires heat to reach its peak lubricating properties. Push your speeds higher for the best tool life and finish.

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.
