TaeguTec CNMG120404ML TT5080
The Tough-Choice Specialist: High-Stability CVD Grade for Challenging Cast Iron Cuts
Product Overview
"Which carbide insert grade is best for interrupted cuts or machining abrasive cast iron where edge chipping is a constant threat?"
The TaeguTec CNMG120404ML TT5080 is an 80° rhombic turning insert designed to bridge the gap between high speed and extreme toughness. Featuring the TT5080 CVD (Chemical Vapor Deposition) grade, this insert utilizes a specialized alumina coating that provides excellent heat resistance while maintaining a highly shock-resistant substrate. The ML (Medium-Light) chipbreaker is engineered with a positive rake and sharp geometry, significantly reducing cutting forces and vibrations, making it the ideal choice for ductile iron, gray iron, and even heavy-duty steel applications involving unstable setups.
Key Features
Built with a specialized substrate that absorbs mechanical shocks, perfect for interrupted cuts or crusty castings.
Sharp cutting edge reduces the power required from the machine spindle and minimizes workpiece vibration.
Multi-layer coating provides a durable thermal shield, extending tool life during abrasive ISO K machining.

Verified Global Feedback
"Interrupted Cut King"
We were chipping inserts every 10 parts on ductile iron castings until we switched to TT5080. Now we get a full shift per corner.
— Castings GmbH (Germany)"No More Chatter"
The ML breaker really helps on our lighter lathes. Very sharp, low pressure, and the finish is excellent for a tough grade.
— Precision Lathe Works (USA)"Solid and Predictable"
Consistent performance across a huge batch of gray iron housings. Edge wear was even and predictable.
— Heavy Industrial (Japan)Frequently Asked Questions
1. Is TT5080 better than TT5100?
TT5080 is tougher (better for shock), while TT5100 is more wear-resistant (better for high-speed continuous cuts). Choose TT5080 for interrupted or unstable conditions.
2. Can I use this for Stainless Steel?
While TT5080 can handle some steels, we recommend our dedicated ISO M grades for the best results in stainless steel.

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.
