TaeguTec TCMT16T304MT TT9225
The New Standard in Steel Machining: High Speed Meets Ultimate Stability
Product Overview
"Which insert offers the best balance of tool life and productivity for general-purpose steel turning?"
The TaeguTec TCMT16T304MT TT9225 is a premium 16mm triangular turning insert optimized for Steel (ISO P) applications. The TT9225 grade represents the pinnacle of TaeguTec's CVD coating technology, featuring a high-toughness substrate paired with an advanced alumina coating that provides exceptional resistance to plastic deformation. The MT (Medium Turning) chipbreaker is designed with a balanced geometry that excels in varying depths of cut, ensuring consistent chip breaking and preventing the "bird-nesting" of chips. For CNC workshops demanding a high-conversion tool that reduces downtime across a variety of carbon and alloy steels, the TT9225 is the indispensable choice.
Core Advantages
Superior thermal stability allows for higher cutting speeds (Vc) without compromising the integrity of the cutting edge.
Designed to withstand light interruptions and unstable setups, providing predictable performance in real-world shop conditions.
Reduces friction and cutting force, resulting in lower power consumption and improved surface finish on the workpiece.

— Mark R., USA"The 16mm MT breaker handles chips beautifully in 4140 steel. Exceptional tool life."
— Hans G., Germany"Excellent dimensional stability on my CNC lathe. Top quality TaeguTec."
— Tanaka S., Japan"Fast delivery to Italy. Great performance on medium carbon steels."
— Luca M., Italy"Best price for genuine TaeguTec. This grade is a workhorse in our shop."
— Sarah J., USAFrequently Asked Questions
A: While it can cut stainless steel, it is optimized for ISO P Steel. For ISO M Stainless, we recommend PVD grades like TT9080 for better edge life.
A: The 0.4mm radius allows for sharper cuts with lower vibration, making it ideal for finishing passes and smaller workpiece diameters.
A: Yes, as long as the boring bar is designed for TCMT 16T3 size inserts with a 7-degree relief angle.

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.
