TaeguTec DNMG150608-MT TT8115
Increased Thickness & Thermal Resistance for High-Velocity Steel Production
Product Overview
"Which insert grade provides maximum thermal stability and vibration resistance during heavy-duty turning of alloy steel?"
The TaeguTec DNMG150608-MT TT8115 is a high-rigidity CVD-coated carbide insert, specifically engineered for ISO P (Steel) and ISO K (Cast Iron). By utilizing the 1506 series (6.35mm thickness), this insert offers a larger thermal sink to dissipate heat generated during high-speed continuous cuts. The TT8115 grade features a thick Alumina (Al2O3) coating that resists crater wear at extreme temperatures. Combined with the MT (Medium Turning) chipbreaker, it delivers exceptional chip control and edge strength, making it the ideal choice for automated CNC workshops requiring consistent precision and long tool life.
Key Features
The 6.35mm profile provides superior vibration dampening and mechanical strength for deep cuts.
Thick CVD coating technology allows for cutting speeds (Vc) up to 450 m/min in carbon steels.
A balanced geometry that ensures smooth chip evacuation while protecting the 0.8mm cutting edge.

Verified Industry Feedback
"Thermal Stability is Key"
We increased our speed to 420 m/min in 4140 alloy steel. The 1506 thickness definitely helps with vibration during deep cuts.
— Precision Machining Group (USA)"Perfekt für hohe Geschwindigkeiten"
Outstanding life in steel finishing. The TT8115 grade handles the heat without any cratering. Excellent Ra values.
— Fertigungstechnik Schmidt (Germany)"Consistency matters"
Very stable performance in mass production. We get consistent tool life across all corners, which is vital for our automation.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Is the 1506 (6.35mm) compatible with my 1504 holder?
Standard holders are often designed for specific thicknesses. Please ensure your toolholder shim/seat is compatible with the 6.35mm thickness (06 series) for proper clamping.
2. Why use TT8115 over TT8125?
TT8115 is optimized for high-speed continuous cuts where heat is the primary failure mode. TT8125 is better for interrupted cuts or standard speeds where toughness is more critical.
