TaeguTec TCMT16T308PC TT8115
Elite CVD Grade for Ultra-High-Speed Steel Finishing
Product Overview
"Which insert is best for maximizing cycle time reduction and surface Ra quality in continuous steel turning?"
The TaeguTec TCMT16T308PC TT8115 is a high-tech 16mm triangular insert specifically developed for high-velocity Steel (ISO P) applications. The TT8115 CVD grade utilizes an advanced coating matrix designed for extreme hardness and chemical stability, allowing it to withstand the intense heat generated during high-speed finishing operations. Paired with the PC (Positive Finishing) chipbreaker, it features a sharp cutting edge and specialized geometry to shear through alloy steels with minimal tool pressure. The 0.8mm corner radius provides enhanced edge security, ensuring dimensional stability across long production runs while delivering an exceptional mirror-like finish.
Core Advantages
Thick CVD coating optimized for maximum thermal shielding, allowing Vc speeds over 350 m/min in specific steels.
Designed for finishing depths of cut (Ap), effectively curling chips even in gummy low-carbon steels.
The TT8115 substrate resists the chemical wear and deformation typical of high-velocity dry or wet machining.

"TT8115 is incredible for high-volume shaft production. I pushed the speed by 30% and the finish is still perfect."
— Jason R., USA"Perfekt für die Serienfertigung. Extreme Verschleißfestigkeit bei legiertem Stahl."
— Werner H., Germany"Genuine quality. Consistent tool life across thousands of parts in our Tokyo plant."
— Yuki M., Japan"Finitura superficiale superiore su acciaio 4140. Molto stabile."
— Alessandro F., Italy"Great productivity boost. Best finishing grade we've tested for precision steel work."
— Simon T., UKFrequently Asked Questions
A: No. TT8115 is a high-hardness grade optimized for wear resistance. For heavy interruptions, the TT9225 or TT9080 grades are much safer options.
A: The 0.8mm radius is stronger than the 0.4mm, allowing for higher feed rates while maintaining a smooth surface finish (theoretical Ra) when the machine is stable.
A: TT8115 is primarily a Steel (ISO P) grade. For high-speed stainless finishing, we recommend the PVD TT9080 for better edge integrity.

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.
