TaeguTec CNMG120404PC TT9225
The Versatile Standard: Premium CVD Grade for Balanced Steel Finishing Excellence
Product Overview
"Which carbide insert is best for general steel finishing where I need a reliable balance between long tool life and the ability to handle slight interruptions?"
The TaeguTec CNMG120404PC TT9225 is the "workhorse" of the steel turning industry. Optimized for ISO P (Steel), the TT9225 CVD grade combines a high-toughness substrate with a multi-layered alumina coating. This allows it to thrive in a wide range of cutting conditions, from continuous to light interrupted cuts. The PC (Positive Finishing) chipbreaker features a sharp, precision-ground geometry that significantly reduces cutting resistance, ensuring a mirror-like finish and high dimensional stability on carbon and alloy steels.
Key Features
A balanced CVD grade that prevents chipping while maintaining excellent crater wear resistance in steel applications.
Sharp positive rake designed for low-depth-of-cut finishing passes, minimizing vibration and heat build-up.
Perfect for intricate details and high-spec surface requirements on precision steel components.

Verified Global Feedback
"The Most Reliable Finish"
We use TT9225 for all our general steel finishing. The 0.4mm radius is perfect for fine detail, and the PC breaker never fails to break chips perfectly.
— Precision Lathe Works (USA)"Versatile and Sharp"
Finally a finishing insert that doesn't chip when the machine isn't 100% rigid. Great results on SCM440 alloy steel.
— M&K Engineering (Germany)"Excellent Surface Quality"
Very consistent tool life. Surface finish is predictable and dimensional accuracy is maintained across long batches.
— Fuji Heavy Machining (Japan)Frequently Asked Questions
1. Can I use TT9225 for interrupted cuts?
Yes, TT9225 is specifically engineered with higher toughness than TT9215, making it suitable for finishing steel parts with slight interruptions or unstable setups.
2. What is the benefit of the PC chipbreaker?
The PC (Positive Finishing) breaker has a sharp geometry that lowers cutting pressure, which is critical for achieving fine finishes and preventing vibration on small depths of cut.

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.
