TaeguTec TCMT110204MT TT8115
The High-Speed Finishing Specialist: Maximum Wear Resistance for Stable Steel Turning
Product Overview
"Push your cycle times to the limit with the TT8115—the hardest PVD grade in the 8100 series for maximum tool life at high surface footages."
The TaeguTec TCMT110204MT TT8115 is an 11mm triangular turning insert optimized for high-productivity Steel (ISO P) applications. While many PVD grades focus on toughness, the TT8115 grade is specifically engineered for wear resistance and high-speed stability. It is the ideal choice for continuous cuts where dimensional accuracy over long runs is paramount. The MT (Medium Turning) chipbreaker provides a versatile geometry that reduces cutting forces while maintaining excellent chip evacuation, while the 0.4mm corner radius ensures a high-quality surface finish on the workpiece.
Core Advantages
A specialized PVD coating with ultra-high hardness that resists abrasive wear better than standard grades in carbon and alloy steels.
Engineered to maintain a sharp cutting edge at elevated temperatures, allowing for increased Vc (cutting speed) and reduced cycle times.
The MT chipbreaker's land design provides stable chip breaking in finishing to medium turning, even in "gummy" low-carbon steels.

Compatible Tooling Systems
This insert is precision-matched for TCMT 11 size tool holders, boring bars, and external turning systems.
Industrial Applications
- High-speed turning of automotive steel gears and shafts.
- Finishing of hydraulic cylinders and precision valve components.
- Mass production of small-to-medium steel parts where downtime for tool changes must be minimized.
- Machining of hardened steel surfaces where abrasive wear is the primary failure mode.
Understanding the Grade
Selected here. The hardest PVD grade for ISO P. Best for high speeds and continuous cuts in steel.
The balanced alternative for shops needing a mix of toughness and wear resistance in variable setups.
Frequently Asked Questions
1. When should I choose TT8115 over TT8125?
Choose TT8115 (this grade) when your setup is rigid and you are looking to maximize surface speed or tool life in continuous cuts. If you have interrupted cuts or unstable clamping, the tougher TT8125 is safer.
2. Is the 11mm size better than the 09mm for finishing?
The 11mm size offers more carbide mass and surface contact in the tool holder pocket, which can help dampen vibrations more effectively than the 09mm size, leading to a better finish on larger workpieces.

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.
