TaeguTec CCMT09T308MT TT7015
Advanced PVD Grade for High-Speed Stainless Steel & Super Alloy Finishing
Product Overview
"Which insert grade offers the best heat resistance and edge stability for finishing 316 stainless steel and aerospace alloys without rapid tool wear?"
The TaeguTec CCMT09T308MT TT7015 is an 80° rhombic turning insert engineered specifically for ISO M (Stainless Steel) and ISO S (Heat Resistant Alloys) machining. Featuring the high-performance TT7015 PVD coating, this grade is designed to thrive in high-temperature cutting zones where standard carbide fails. The MT chipbreaker (Medium Turning) provides a versatile balance between a sharp cutting edge and necessary strength, ensuring stable chip evacuation in gummy materials. With a 0.8mm nose radius, it provides increased edge toughness and excellent surface finish stability for precision components.
Key Features
A specialized TiAlN-based PVD coating that provides extreme hardness and thermal stability at higher cutting speeds.
Optimized for medium-to-fine finishing, ensuring reliable chip breaking in high-ductility materials like 304/316 stainless.
The 0.8mm radius offers a stronger cutting edge and better surface finish overlap for efficient production cycles.

Why Choose TaeguTec?
TaeguTec, as a member of the IMC Group, is a global leader in high-performance metallurgy. The TT7015 grade is the direct result of intensive research into the work-hardening characteristics of stainless steels. Unlike standard PVD inserts, TaeguTec’s coating technology maintains edge sharpness longer, drastically reducing the thermal stresses that lead to workpiece deformation. When you choose TaeguTec, you are investing in South Korean precision that maximizes machine uptime and significantly lowers your cost-per-part in tough materials.
Verified Global Feedback
"Reliable in 316L"
We were burning through carbide on 316L finishing passes. Switched to TT7015 and tool life nearly doubled. Surface finish is flawless.
— Precision Med-Components (USA)"Hervorragend bei Inconel"
Excellent heat resistance. Dimensions stay tight throughout the entire batch. The MT chipbreaker is very stable.
— Luftfahrt-Ingenieurwesen (Germany)"Ottima per Inox"
Handles the gummy chips of 304 stainless very well. Very predictable wear pattern.
— Meccanica di Precisione (Italy)Frequently Asked Questions
1. Is TT7015 suitable for Carbon Steel (ISO P)?
While possible, it is specifically optimized for Stainless and Super Alloys. For Carbon Steel, we recommend TT8125 or CT3000 for better productivity.
2. Should I use coolant with this grade?
Yes. When machining stainless steel, high-pressure coolant is highly recommended to manage heat and prevent built-up edge.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
