TaeguTec TCMT16T304PC TT9225
High-Productivity CVD Grade for Precision Steel Machining
Product Overview
"Which insert is the most reliable for high-speed finishing of carbon and alloy steels in large production runs?"
The TaeguTec TCMT16T304PC TT9225 is a premium 16mm triangular insert designed for high-efficiency Steel (ISO P) turning. The TT9225 CVD grade features a thick Aluminum Oxide (Al2O3) coating layer that provides an exceptional thermal barrier, allowing for significantly higher cutting speeds compared to PVD alternatives. This grade is specifically engineered to combat crater wear and plastic deformation. Paired with the PC (Positive Finishing) chipbreaker, which utilizes a sharp rake angle to shear cleanly through steel, it delivers incredible surface Ra values and dimensional consistency. It is the industrial standard for finishing operations in automotive, machinery, and general engineering components.
Core Advantages
Superior heat resistance and hardness for high-speed (Vc) machining, ensuring maximum parts-per-edge.
Optimized for light depths of cut, providing excellent chip control and preventing surface marring.
The TT9225 substrate provides a stable platform that resists flank wear even in continuous long-run passes.

"TT9225 is my go-to for 4140 steel. The CVD coating holds up much better at high speeds than my previous brand."
— Steven B., USA"Sehr gute Oberflächenqualität. The PC breaker curls chips perfectly on soft mild steel."
— Klaus M., Germany"Fast delivery and genuine quality. The tool life is double what we expected."
— Jun T., Japan"Ottima resistenza all'usura su acciaio bonificato. Finitura impeccabile."
— Roberto D., Italy"The best finishing insert for our CNC lathes. Precision and speed in one package."
— Greg P., UKFrequently Asked Questions
A: No. CVD coatings for steel are not suitable for aluminum as they cause adhesion. For aluminum, please use uncoated or polished carbide grades.
A: TT9225 is a finishing grade optimized for continuous cuts. For heavy interruptions in steel, a tougher grade like TT5080 or TT9080 (PVD) is recommended.
A: The 0.4mm radius reduces cutting pressure and is ideal for high-precision finishing where a fine surface finish and close tolerances are required.

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.
