TaeguTec CCMT060204MT TT7015
Advanced PVD Coated Grade for Precision Stainless Steel & Super Alloy Machining
Product Overview
"Which insert grade offers the best balance of heat resistance and edge sharpness for finishing tough 304 or 316 stainless steel at higher speeds?"
The TaeguTec CCMT060204MT TT7015 is an 80° rhombic turning insert engineered for ISO M (Stainless Steel) and ISO S (Heat Resistant Alloys). Featuring the high-performance TT7015 PVD coating, this insert provides exceptional resistance to built-up edge (BUE) and thermal cracking. The MT chipbreaker (Medium Turning) is specifically designed to manage the gummy chips typical of stainless steel, offering stable chip breaking even at light depths of cut. This ensures superior surface finishes and tight dimensional tolerances in high-precision components.
Key Features
A specialized TiAlN-based coating that maintains extreme hardness and oxidation resistance at high cutting temperatures.
Versatile chipbreaker design that prevents chip entanglement and provides stable cutting forces in gummy materials.
Micro-engineered edge sharpness reduces work hardening of the workpiece surface during finishing passes.

Why Choose TaeguTec?
TaeguTec, as part of the IMC Group, is a global powerhouse in material science and metalworking solutions. The TT7015 grade is the result of intensive R&D into the thermal behavior of stainless steels. Unlike standard inserts, TaeguTec PVD coatings provide a smoother surface and a sharper edge that drastically reduces work hardening—a common failure point in stainless machining. When you choose TaeguTec, you are choosing South Korean manufacturing excellence designed to push your machine's limits while maintaining high yield rates.
Verified Global Feedback
"Best for 316 Stainless"
We struggled with built-up edge until we switched to TT7015. Now our finishing passes are clean and tool life is up by 40%.
— Precision MedTech (USA)"Hervorragende Oberfläche"
Excellent surface quality on duplex stainless. The MT chipbreaker is very reliable for small parts.
— Feinwerktechnik GmbH (Germany)"Ottimo per Leghe"
Very stable when machining Titanium. The edge stays sharp much longer than cheaper alternatives.
— Aerospace Componenti (Italy)Frequently Asked Questions
1. Is TT7015 suitable for Carbon Steel?
While it can cut steel, it is specifically optimized for Stainless and Super Alloys. For Carbon Steel, we recommend the TT8115 or CT3000 grades.
2. Does this insert require coolant?
High-pressure coolant is highly recommended when machining stainless steel to prevent work hardening and assist in chip evacuation.
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.
