TaeguTec CNMG120408ML TT5100
High-Speed Performance: Precision ML Chipbreaker meets Advanced CVD Wear Resistance
Product Overview
"Which carbide insert grade is best for reducing vibration and ensuring a mirror finish on abrasive gray iron at high cutting speeds?"
The TaeguTec CNMG120408ML TT5100 is an 80° rhombic turning insert specifically engineered for ISO K (Cast Iron) applications. Featuring the premium TT5100 CVD grade, it utilizes a thick Al2O3 coating to provide unparalleled resistance to abrasive wear and heat. The ML (Medium-Light) chipbreaker geometry is designed with a sharp, positive rake angle to shear through material with minimal resistance, significantly lowering cutting forces and preventing chatter in light to medium turning operations. The 0.8mm radius provides a robust cutting edge for high-productivity cycles.
Key Features
A specialized alumina layer provides a hard thermal barrier against the abrasive nature of gray and ductile iron.
The sharp ML geometry lowers the power requirement and reduces vibration, ideal for long-reach or thin-walled parts.
The 0.8mm radius offers superior edge strength, allowing for consistent results across long-duration production runs.

Verified Global Feedback
"Superb Life on Gray Iron"
Switched to TT5100 for our rotor production. The wear resistance on abrasive iron is second to none. Very predictable life.
— Precision Casting (Germany)"Reduced Chatter Instantly"
The ML breaker works perfectly for our lighter lathes. We get a clean finish without the machine shaking on ductile iron parts.
— CNC Solutions (USA)"High Speed Stability"
The 0.8mm radius is very robust. We run high Vc and it stays stable throughout the entire production shift.
— Tech Industries (Japan)Frequently Asked Questions
1. Is TT5100 suitable for Steel turning?
No. TT5100 is specifically optimized for abrasive Cast Iron. For Steel turning, please use our TT8125 or TT8115 grade options.
2. What makes the ML chipbreaker special?
The ML breaker has a sharp, positive rake that lowers cutting forces. It is the best choice for vibration reduction and excellent surface finish.

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.
