TaeguTec CNMG120404PC TT8115
Precision Finishing Excellence: High-Heat Resistance PVD Grade for Exotic Alloys
Product Overview
"Which turning insert is most effective for achieving a mirror-like finish on Titanium and Inconel while maintaining long tool life at higher cutting speeds?"
The TaeguTec CNMG120404PC TT8115 is a specialized 80° rhombic insert engineered for high-precision finishing in ISO M (Stainless Steel) and ISO S (Heat Resistant Super Alloys). The TT8115 PVD grade features advanced thermal stability and high-hardness coating layers that prevent chemical wear in high-temperature zones. The PC (Positive Finishing) chipbreaker is designed with a sharp cutting edge to minimize work hardening and cutting resistance, ensuring exceptional surface integrity on sensitive workpieces.
Key Features
TT8115 provides a superior heat barrier, allowing for increased cutting speeds without sacrificing edge sharpness.
A sharp, positive rake angle optimized for fine finishing and low-force machining of thin-walled parts.
High-density carbide base ensures extreme edge retention and dimensional accuracy across long production runs.

Verified Global Feedback
"Flawless Finish on Ti"
We use these for Titanium medical parts. The PC breaker is incredibly sharp—no burrs and the surface finish is excellent right off the machine.
— MedTech Solutions (USA)"Best for Aerospace"
Finally a PVD grade that doesn't burn out on Inconel. The TT8115 handles the high heat perfectly for our finishing passes.
— Aero-Precision GmbH (Germany)"Very Consistent"
The 0.4mm radius is perfect for tight tolerances. We get very predictable tool life across our 316L production runs.
— Precision Components (Japan)Frequently Asked Questions
1. Is the PC chipbreaker suitable for roughing?
No, the PC (Positive Finishing) breaker is designed for light finishing cuts. For roughing, we recommend the MT or RT geometries.
2. How does TT8115 handle dry machining?
While highly heat resistant, using high-pressure coolant is strongly advised for finishing Stainless and Super Alloys to ensure chip evacuation and surface quality.

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.
