TaeguTec TCMT16T304MT TT8115
High-Speed Industrial Productivity: Maximum Wear Resistance and Stability for Large Diameter Steel Turning
Product Overview
"Combine the mass of a 16mm triangular substrate with the hardness of the TT8115 grade to dominate high-speed finishing runs in steel."
The TaeguTec TCMT16T304MT TT8115 is a robust 16mm triangular turning insert engineered for high-performance Steel (ISO P) applications. This insert is designed for large-scale components where cycle time reduction is critical. The TT8115 grade is TaeguTec's most wear-resistant PVD coating in the 8100 series, providing a harder surface that excels in continuous cuts at high surface speeds. The MT (Medium Turning) chipbreaker offers a versatile positive rake geometry that effectively manages chip flow in both medium turning and precision finishing. With a 0.4mm corner radius, this insert provides the ultimate surface finish and dimensional precision for high-output CNC environments.
Core Advantages
A specialized PVD coating designed specifically to resist abrasive wear at high temperatures, perfect for high-speed automated lines.
The increased carbide volume provides exceptional thermal dissipation and structural rigidity, preventing edge deformation during long cuts.
Optimized for reduced cutting forces, this chipbreaker prevents heat transfer into the workpiece, ensuring superior surface integrity.

- Internal boring of long-reach steel housings requiring stable thermal management.
- Continuous high-output machining of carbon steel parts on automated CNC lathes.
Choosing the Grade
Selected here. The hardest PVD option. Designed for maximum surface speed and long tool life in rigid steel setups.
The alternative for shops requiring higher edge toughness for light interruptions or less stable workholding.
Frequently Asked Questions
1. When is TT8115 better than TT8125 in a 16mm size?
Use TT8115 (this grade) when you have a very stable setup and are machining high-carbon or abrasive alloy steels at high speeds. It provides a harder cutting edge that resists wear significantly longer than TT8125.
2. Does this work for finishing small parts?
While it can, the 16mm size is usually optimized for medium-to-large workpieces. The 0.4mm radius is perfect for fine finishes, but for small diameter internal boring, consider the 09 or 11mm sizes for better clearance.

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.
