TaeguTec CNMG120408 TT7015
Engineered for High-Speed Cast Iron Machining: The CVD Performance Leader
Product Overview
"Which insert grade offers the best tool life and thermal stability when turning abrasive gray cast iron at maximum spindle speeds?"
The TaeguTec CNMG120408 TT7015 is a high-performance 80° rhombic insert purpose-built for ISO K (Cast Iron). Featuring an advanced CVD (Chemical Vapor Deposition) coating, the TT7015 grade is characterized by extreme hardness and resistance to abrasive wear. Designed specifically for the high-temperature environment of high-velocity cast iron turning, this insert excels in Gray Cast Iron (GG) and Nodular Cast Iron (GGG), ensuring dimensional precision and superior surface Ra over extended production cycles.
Key Features
Thick thermal barrier provides exceptional resistance to crater wear and heat during continuous high-speed cutting.
Optimized substrate prevents rapid edge rounding common in abrasive cast iron machining.
Provides a perfect balance between surface finish and edge strength for medium-duty turning.

Verified Global Feedback
"Reliable Performance"
Outstanding on brake drum production. We were able to push the speeds without any early edge failure.
— Precision Machining (USA)"Top Tier for GG25"
Increased tool life by 25% on our cast iron runs compared to our previous European supplier. Great value.
— Automobil GmbH (Germany)"Excellent on Ductile"
Heat resistance is exceptional. Even during long dry cuts, the insert remains dimensionally stable.
— Industrial Foundry (Italy)Frequently Asked Questions
1. Can TT7015 be used for steel (ISO P)?
TT7015 is specifically optimized for the abrasive nature of Cast Iron. For steel, we recommend TT9225 or TT9235 grades.
2. Is this grade suitable for dry cutting?
Yes. TT7015 is ideal for dry machining in cast iron, as its thick CVD alumina coating provides an excellent heat shield.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
