TaeguTec CNMG160612MT TT5100
Optimized for Cast Iron: High-Speed CVD Grade for Maximum Productivity
Product Overview
"Which insert grade provides the longest tool life and best wear resistance when turning grey or ductile cast iron at high cutting speeds?"
The TaeguTec CNMG160612MT TT5100 is the ultimate solution for ISO K (Cast Iron) applications. The TT5100 CVD grade features a thick Al2O3 coating combined with a high-hardness substrate, specifically engineered to withstand the abrasive nature of cast iron. The MT (Medium-Tough) chipbreaker geometry reduces cutting forces while maintaining edge integrity, making it ideal for stable roughing to semi-finishing operations on CNC lathes.
Key Features
A thick, multi-layered alumina coating provides exceptional heat shield properties and crater wear resistance.
The larger insert body allows for deeper cuts and higher stability in heavy-duty machining cycles.
A versatile breaker that handles chips perfectly in both continuous and slightly interrupted iron cuts.

Verified Global Feedback
"Amazing Wear Resistance"
We turn 500 grey iron brake drums daily. The TT5100 grade consistently outlasts competitors by 25%, maintaining tolerance effortlessly.
— Automotive Spares (Italy)"Perfect for GG25"
Finally found an insert that doesn't crater at high speeds. The CNMG 16 size provides incredible stability on our CNC lathes.
— Machine Works Ltd (United Kingdom)"Reliable and Fast"
Great chip control with the MT breaker. We use it for semi-finishing ductile iron housings. Very dependable.
— Precision Foundry (USA)Frequently Asked Questions
1. Can I use TT5100 for Steel machining?
No, TT5100 is strictly optimized for ISO K (Cast Iron). For Steel (ISO P), we recommend using grades like TT8125 or TT8115.
2. What is the benefit of the 1.2mm radius?
The 1.2mm corner radius provides a much stronger cutting edge, allowing for higher feed rates and better heat dissipation compared to smaller radii.
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.
