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.
