TaeguTec CCMT120404PC TT8115
The High-Velocity Specialist: Ultimate Wear Resistance for Precision Steel Finishing
Product Overview
"Which insert grade is the best for high-speed continuous turning of steel while maintaining a perfect surface finish and extreme tool life?"
The TaeguTec CCMT120404PC TT8115 is a high-performance 80° rhombic insert designed for ISO P (Steel) finishing. Utilizing the highly wear-resistant TT8115 CVD coating, this grade is optimized for maximum cutting speeds in stable conditions. The PC (Precision Finishing) chipbreaker geometry features a sharp cutting edge and specialized rake angle to reduce cutting forces, preventing heat buildup and ensuring superior chip evacuation in light-duty finishing applications.
Key Features
Advanced CVD coating with high Al2O3 content for exceptional crater wear resistance at ultra-high surface speeds.
Optimized for low depths of cut (DOC), providing stable chip breaking and excellent surface Ra values.
Designed to withstand the intense temperatures of dry machining and high-velocity continuous cutting.

Verified Global Feedback
"Incredible Speed"
We pushed our cutting speeds by 30% on low-carbon steel. The TT8115 doesn't even flinch. Finish is mirror-smooth.
— High-Tech Machining (USA)"Beste Standzeit"
Very consistent tool life at high speeds. The PC chipbreaker works perfectly for our finishing passes.
— Präzisionsfertigung AG (Germany)"Top Performance"
Great for high-volume automotive parts. Reduced our tool changes significantly. Very reliable.
— Automotive Precision (Japan)Frequently Asked Questions
1. Is TT8115 good for interrupted cuts?
TT8115 is a high-hardness grade. It is best suited for continuous cuts. For heavy interruptions, the TT8125 or TT8135 grades are better suited.
2. Can I use this for Stainless Steel?
This grade is optimized for ISO P Steel. For Stainless Steel (ISO M), we recommend TaeguTec’s TT9080 or TT9225 grades.

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.
