TaeguTec TCMT16T308MT TT5100
Premium CVD Coated Insert for High-Velocity Cast Iron Turning
Product Overview
"Which insert is best for high-speed machining of abrasive Grey or Ductile Cast Iron?"
The TaeguTec TCMT16T308MT TT5100 is the definitive answer for industrial cast iron applications. This 16mm triangular insert utilizes the TT5100 CVD (Chemical Vapor Deposition) grade, featuring a thick Alumina (Al2O3) layer that acts as a superior thermal shield against the abrasive nature of graphite. The MT (Medium Turning) chipbreaker is engineered with a positive rake angle to shear through brittle materials efficiently, while the 0.8mm corner radius provides the structural integrity required for higher feed rates and long-duration finishing in high-output CNC environments.
Key Features
The TT5100 grade offers extreme wear resistance, specifically designed to combat flank wear in abrasive ISO K materials.
Engineered for high surface footages (Vc), allowing for maximum RPM without compromising the carbide substrate.
A balanced chipbreaker that reduces cutting pressure and prevents vibration in large-diameter workpieces.

"TT5100 is a monster for grey iron. We doubled our Vc from 200 to 400 m/min with no chipping."
— Hans G., Germany"Fast delivery to Tokyo. The MT chipbreaker works great on our ductile iron pulleys."
— Tanaka S., Japan"Solid performance in US job shop. Best cost-per-edge for 16mm inserts."
— Mike R., USA"Ottimo per ghisa. Wear resistance is world-class."
— Luca B., Italy"Standard choice for our CNC production lines. Highly reliable."
— David L., USAFrequently Asked Questions
A: While possible, it is not recommended. TT5100 is specifically optimized for Cast Iron. For Steel, we recommend the TT8100 series.
A: MT represents 'Medium Turning'. It provides a balanced geometry that handles both semi-finishing and medium roughing depths efficiently.
A: Yes, as long as the boring bar is designed for TCMT 16T3 (3/8" I.C.) inserts with a 7-degree relief.
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.
