TaeguTec CCMT120404PC TT9080
The Stainless Steel Specialist: Ultra-Hard PVD Coating for Challenging Alloys
Product Overview
"Which insert grade provides the best balance of edge toughness and heat resistance when turning 304/316 stainless steel or Inconel?"
The TaeguTec CCMT120404PC TT9080 is a high-precision 80° rhombic insert optimized for ISO M (Stainless Steel) and ISO S (Heat-Resistant Alloys). Utilizing a sophisticated sub-micron PVD (Physical Vapor Deposition) coating, the TT9080 grade is engineered to combat the unique challenges of "gummy" materials, such as built-up edge (BUE) and notch wear. The PC (Precision Cutting) chipbreaker geometry features a sharp cutting edge and positive rake angle, specifically designed to reduce radial cutting forces and maintain thermal stability during high-precision finishing operations.
Key Features
Smooth, heat-resistant TiAlN-based coating reduces friction and prevents chemical wear at high temperatures.
Sharp geometry provides excellent chip control at light depths of cut, preventing work-hardening of the workpiece.
Specialized carbide substrate allows for reliable performance even in light interrupted cuts or unstable setups.

Verified Global Feedback
"Ultimate Performance on 316L"
We struggled with built-up edge using other brands. The TT9080 solved it instantly. The PC chipbreaker is fantastic for finishing.
— Precision Machining Co. (USA)"Beste für Edelstahl"
Very consistent tool wear even on tough heat-resistant alloys. Highly reliable for our production lines.
— Maschinenbau AG (Germany)"Top Tier PVD"
Using this for aerospace boring. Heat management is excellent and the surface finish is impeccable.
— AeroSpace Components (Italy)Frequently Asked Questions
1. Can TT9080 be used for Steel (ISO P)?
Yes, it is excellent for alloy steel in unstable conditions or small diameter boring, but for high-speed mass production of steel, TT8125 is usually more efficient.
2. Why use a 0.4mm radius instead of 0.8mm?
The 0.4mm radius (016) is ideal for finishing operations requiring high dimensional accuracy and lower radial cutting forces, especially in boring or thin-walled parts.

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.
