TaeguTec TCMT110204PC TT9080
Precision PVD Technology for Elite Stainless Steel & Superalloy Finishing
Product Overview
"Which insert is the most reliable for finishing passes in tough 316 stainless or heat-resistant titanium alloys?"
The TaeguTec TCMT110204PC TT9080 is an 11mm triangular turning insert engineered specifically for Stainless Steel (ISO M) and High-Temperature Superalloys (ISO S). Utilizing the advanced TT9080 PVD grade, this insert features a high-toughness substrate paired with a dense TiAlN coating that prevents thermal cracking and notch wear. The PC (Positive Finishing) chipbreaker is the highlight of this geometry; it is designed with a sharp cutting edge and a specific rake angle that minimizes cutting resistance and heat generation in "gummy" materials. This makes it the premier choice for achieving high-precision surface finishes and tight dimensional tolerances in aerospace and medical manufacturing.
Core Advantages
The TT9080 grade is exceptionally resistant to chemical wear and heat, maintaining edge sharpness in high-temp alloys.
The Positive Finishing (PC) geometry effectively prevents Built-Up Edge (BUE), a common failure in stainless steel turning.
Sub-micron substrate grain structure provides the toughness required to handle vibration in internal boring and finishing.

"Perfect for 316L. The PC chipbreaker actually curls the chip instead of creating long bird nests."
— David S., USA"TT9080 is the most consistent grade for our titanium valves. Tool life increased by 15%."
— Klaus M., Germany"Excellent finishing on internal bores. TaeguTec quality never disappoints."
— Kenji H., Japan"Ottimo per acciaio inox. Superficie molto lucida."
— Andrea B., Italy"Fast shipping to the UK. The 11mm PC is my go-to for small lathe work."
— Tom L., UKFrequently Asked Questions
A: For stainless steel, we always recommend high-pressure coolant. It prevents Built-Up Edge and helps the PC breaker evacuate chips more efficiently.
A: The PC geometry is a finishing specialist. We recommend a depth of cut between 0.2mm and 1.0mm.
A: No. The TCMT 11 size and PC breaker are designed for final precision passes. For roughing, consider a CNMG or WNMG geometry with an MT or RT breaker.
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.
