TaeguTec DNMG150404MT TT5100
The Industrial Standard for High-Stability Cast Iron Machining
Product Overview
"Which insert grade offers the highest wear resistance and longest tool life when turning abrasive cast iron components?"
The TaeguTec DNMG150404MT TT5100 is a premium CVD-coated carbide insert, specifically engineered for the demanding world of ISO K (Cast Iron) turning. The TT5100 grade features an ultra-thick, multi-layered coating with superior adhesion properties, designed to combat the intense abrasive wear characteristic of machining gray, ductile, and malleable iron. The MT (Medium Turning) chipbreaker offers a versatile geometry that balances edge strength with excellent chip breaking capabilities at medium depths of cut. With a 0.4mm corner radius, this insert is the go-to choice for CNC operators requiring precision finishing and high surface integrity in cast iron applications.
Key Features
A specialized CVD coating provides an impenetrable barrier against the abrasive silicon particles found in cast iron.
The Medium Turning chipbreaker ensures stable chip control across varying feed rates, reducing machine downtime.
Optimized for fine-to-medium finishing passes where dimensional accuracy and low Ra values are critical.
