TaeguTec SCMT09T308-MT TT5100
Mastering ISO K: High-Velocity Square Insert for Professional Cast Iron Machining
Product Overview
"Which square positive insert offers the best heat resistance and tool life when turning abrasive gray iron at high cutting speeds?"
The TaeguTec SCMT09T308-MT TT5100 is an industrial specialist for ISO K (Cast Iron) turning. The TT5100 grade features a sophisticated thick-film CVD Alumina coating that acts as a robust thermal shield, preventing crater wear during high-speed iron cutting. The MT (Medium) chipbreaker geometry is optimized for medium-duty applications, providing stable chip breaking in ductile iron and minimizing dust when machining gray iron. This combination delivers exceptional dimensional accuracy and surface integrity for high-volume CNC production.
Key Features
Thick alumina coating provides superior abrasive wear resistance and thermal protection for continuous iron cutting.
Specifically tuned for medium applications to ensure smooth chip evacuation and reduced cutting pressure.
The 0.8mm nose radius provides a robust cutting edge and improved surface finish for general-purpose turning.

Verified Global Feedback
"Outstanding for Brake Discs"
We use these for high-volume iron disc turning. The TT5100 grade handles the heat much better than our previous grade. Tool life is very stable.
— Cast Tech Manufacturing (USA)"Perfekt für Grauguss"
Outstanding toughness. The 0.8 radius gives a great surface finish and the MT breaker controls chips beautifully in gray iron.
— Maschinenbau Müller (Germany)"Grande Affidabilità"
Reliable performance in ductile iron. Very consistent dimensional accuracy over long shifts. Excellent value.
— Meccanica di Precisione (Italy)"High Speed Stability"
We increased our Vc by 15% without losing tool life. The CVD coating is very thick and robust. Top quality.
— Sato Heavy Industries (Japan)Frequently Asked Questions
1. Can I use SCMT on Steel (ISO P)?
While possible, TT5100 is specifically optimized for Cast Iron. For steel, we recommend CVD grades like TT8115 or TT8125.
2. Why use a square positive insert?
The Square Positive shape offers lower cutting forces compared to negative inserts, making it ideal for internal boring or lower-horsepower CNC machines.
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.
