TaeguTec CCMT09T308MT TT9225
Master the Heat: High-Productivity CVD Turning for Stainless Steel Components
Product Overview
"Which insert grade provides the longest tool life and best surface integrity during high-speed continuous turning of austenitic stainless steels?"
The TaeguTec CCMT09T308MT TT9225 is a premium 80° rhombic insert engineered specifically for ISO M (Stainless Steel). Featuring TaeguTec’s advanced CVD coating technology, the TT9225 grade offers an unparalleled thermal barrier, allowing for aggressive cutting speeds (Vc) that PVD grades simply cannot match. The MT chipbreaker geometry is paired with a reinforced 0.8mm corner radius, providing excellent chip control and edge security, making it the ultimate solution for high-productivity finishing and medium turning in challenging stainless alloys.
Key Features
Thick Al2O3 layer ensures maximum resistance to crater wear and thermal deformation at high velocities.
The 0.8mm (032) corner radius provides the mechanical strength needed for light interrupted cuts and higher feed rates.
Optimized rake angle shears through gummy stainless materials, preventing built-up edge (BUE) and improving surface Ra.

Verified Global Feedback
"Productivity Boost"
We increased our cutting speed by 30% on 316 stainless shafts. The TT9225 grade heat resistance is legendary.
— Precision Machining Co. (USA)"Top Qualität"
Predictable wear and perfect surface Ra. The MT chipbreaker works great even at higher feed rates.
— Metallwerke GmbH (Germany)"Molto Affidabile"
A very reliable grade for mass production. We have significantly fewer tool changes per shift now.
— Meccanica di Precisione (Italy)Frequently Asked Questions
1. Is TT9225 better than PVD for 304 stainless?
For high-speed continuous turning, yes. The CVD coating handles the thermal load much better than PVD coatings.
2. What is the advantage of the 0.8mm radius?
The 0.8mm corner radius provides a stronger cutting edge and allows for higher feed rates compared to a 0.4mm radius, though it requires a more stable setup.

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.
