TaeguTec CNMG120408MP TT5080
Mastering Exotic Alloys: High-Toughness PVD Grade for Heat-Resistant Super Alloys
Product Overview
"Which carbide insert grade provides the most reliable tool life and chip control when turning tough Inconel or gummy Stainless Steels?"
The TaeguTec CNMG120408MP TT5080 is an 80° rhombic insert designed for medium turning of ISO M (Stainless Steel) and ISO S (Super Alloys). The TT5080 PVD grade is engineered with an advanced coating that acts as a thermal barrier against extreme heat. The MP (Medium-Positive) chipbreaker features a sharp yet reinforced cutting edge that prevents notch wear and built-up edge (BUE), ensuring smooth chip evacuation even in the most demanding aerospace materials.
Key Features
Specialized sub-micron substrate with a heat-shielding coating for maximum thermal stability in high-temp alloys.
Optimized geometry that lowers cutting resistance while providing high structural integrity for medium machining.
The industry standard for balancing superior surface finish with the edge strength needed for sustained CNC cycles.

Verified Global Feedback
"The Standard for Inconel 718"
We use TT5080 for all aerospace turning. The MP breaker holds up beautifully against notch wear and the heat resistance is the best we've seen.
— High-Precision Aero (USA)"Reliable on Stainless"
Great results on 316L. Predictable tool life across our CNC shifts and the 0.8 radius gives a perfect surface finish.
— Precision Works GmbH (Germany)"Excellent Performance"
Very consistent. No unexpected chipping even on slightly interrupted cuts in Titanium. Sharp and reliable.
— Advanced Parts (Italy)Frequently Asked Questions
1. What is the benefit of the MP chipbreaker?
The MP (Medium-Positive) breaker is designed for medium turning. It balances sharp cutting action with edge strength, providing excellent chip control in gummy materials like Stainless Steel.
2. Does this grade require high-pressure coolant?
While TT5080 has extreme thermal stability, for Super Alloys, high-pressure coolant is strongly recommended to maintain surface integrity and maximize tool life.

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.
