TaeguTec CNMG120404MT TT5080
The Impact Specialist: High-Toughness CVD Grade for Challenging Cast Iron Machining
Product Overview
"Which insert grade is most reliable for turning abrasive cast iron when the cut is interrupted or the casting surface is uneven?"
The TaeguTec CNMG120404MT TT5080 is an 80° rhombic turning insert engineered for high-reliability performance in ISO K (Cast Iron). While many inserts fail during heavy impact, the TT5080 CVD grade utilizes a specialized tough substrate and advanced thick alumina coating to resist thermal cracking and mechanical shock. The MT chipbreaker features a reinforced geometry that provides excellent chip control across a wide range of feed rates, ensuring stability even in the most demanding CNC turning environments.
Key Features
A uniquely tough carbide substrate designed to absorb mechanical shock during interrupted or heavy-duty cutting.
Reinforced cutting edge prevents micro-chipping while maintaining efficient chip breakability in gray and ductile iron.
Thick thermal barrier coating protects the insert from the high abrasive wear typical of iron machining.

Verified Global Feedback
"Zero Chipping on GGG40"
We were losing inserts to chipping on our ductile iron parts. Switched to TT5080 and the tool life became predictable again. Best toughness in the market.
— Cast Components Ltd (USA)"Handles Interrupted Cuts Easily"
Outstanding for our pump housing production. The cut is interrupted by bolt holes, but the TT5080 edge doesn't budge. Very stable.
— Maschinenbau Kraft (Germany)"Steady Iron Machining"
Good tool life on rough gray iron castings. The 0.4mm radius is perfect for finishing parts after the initial roughing cycles.
— Industrial Tech (Japan)Frequently Asked Questions
1. Is TT5080 suitable for high-speed finishing?
TT5080 is optimized for toughness. For the highest speeds in continuous finishing, we recommend TaeguTec's TT5100 grade.
2. Can I use this on Steel (ISO P)?
While it can turn steel, it is optimized for the abrasive characteristics of Cast Iron. For steel turning, our TT9225 series is the standard choice.

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.
