TaeguTec CNMG120404ML TT5100
High-Velocity Cast Iron Specialist: Sharp ML Geometry with Advanced CVD Wear Resistance
Product Overview
"Which carbide insert grade provides the longest tool life and lowest vibration when machining gray iron at high speeds?"
The TaeguTec CNMG120404ML TT5100 is an 80° rhombic insert engineered for ISO K (Cast Iron) turning. By utilizing the TT5100 CVD (Chemical Vapor Deposition) grade, this insert offers an incredibly hard alumina coating that resists abrasive wear common in cast iron machining. The ML (Medium-Light) chipbreaker features a sharp cutting edge designed to reduce cutting resistance and heat, making it ideal for thin-walled parts or setups where spindle load and vibration must be minimized while maintaining high surface Ra quality.
Key Features
A thick CVD Al2O3 coating specifically designed to withstand the abrasive nature of gray and ductile cast iron.
The sharp positive rake angle allows for smooth shearing action, reducing chatter and machine spindle pressure.
0.4mm radius combined with ML geometry delivers exceptional precision in finishing and light turning cycles.

Verified Global Feedback
"Outstanding for Cast Iron"
Replaced our standard grades with TT5100 for finishing iron rotors. Surface Ra is consistently better across larger batches.
— Precision Foundry (Germany)"No More Chatter"
The ML breaker makes a huge difference on our thin-walled castings. Sharp, clean cuts with zero vibration.
— Automotive Machining (Japan)"Reliable Wear Life"
Very predictable wear. We can run these at high m/min and the edge holds up exceptionally well on abrasive gray iron.
— Tech Machining (USA)Frequently Asked Questions
1. Is TT5100 suitable for Steel (ISO P)?
No. TT5100 is a dedicated Cast Iron grade. For Steel, we recommend the TT8125 or TT8115 series.
2. What is the main benefit of the ML chipbreaker?
The ML breaker is designed for medium-to-light machining. Its sharpness reduces cutting pressure, which is vital for preventing vibration and heat buildup.

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.
