TaeguTec CCMT09T304PC TT9225
Engineered for High-Speed Steel Turning: The CVD Precision Powerhouse
Product Overview
"Which insert grade provides the best thermal stability and wear resistance for high-volume production of steel and stainless parts?"
The TaeguTec CCMT09T304PC TT9225 is a high-performance 80° rhombic insert designed for ISO P (Steel) and ISO M (Stainless Steel). Featuring the advanced TT9225 CVD coating, this grade excels in high-temperature cutting environments, offering a robust barrier against crater wear and plastic deformation. The PC (Precision Cutting) chipbreaker is meticulously crafted with a positive rake and sharp geometry, ensuring excellent chip control at light depths of cut and maintaining high surface Ra standards during finishing operations.
Key Features
Thick Al2O3 layer offers superior heat insulation, allowing for significantly higher cutting speeds and longer tool life.
Low-vibration design ensures stable machining in small boring applications and thin-walled workpieces.
The TT9225 substrate provides the perfect synergy between crater wear resistance and mechanical toughness.

Verified Global Feedback
"Versatile and Efficient"
We use TT9225 for alloy steel and 304 stainless. Tool life is very consistent and surface Ra is excellent.
— Precision Machining (USA)"Top Tier Grade"
Replaced our previous brand with TT9225. We were able to increase cutting speed by 20% without losing life.
— Maschinenbau West (Germany)"Best for finishing"
The PC chipbreaker handles fine chips perfectly on small diameters. Excellent for boring stainless.
— AeroSpace Tech (Italy)Frequently Asked Questions
1. Is TT9225 better than PVD grades for interrupted cuts?
For heavy interrupted cuts, a PVD grade like TT9080 is often tougher. TT9225 (CVD) is optimized for higher speeds and thermal stability in continuous to light interrupted turning.
2. Can I use this grade without coolant?
While TT9225 has high heat resistance, using flood coolant is recommended for stainless steel to prevent built-up edge and ensure chip evacuation.

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.
