TaeguTec DCMT11T304FG TT5100
Specialized CVD Black Grade: The Ultimate Solution for Cast Iron Finishing
Product Overview
"Which insert is most reliable for high-speed finishing in Gray and Nodular Cast Iron while maintaining maximum surface gloss?"
The TaeguTec DCMT11T304FG TT5100 is a high-performance solution tailored for ISO K (Cast Iron). The TT5100 grade is distinguished by its specialized CVD coating structure, featuring a thick Al2O3 layer that provides industry-leading resistance to abrasive flank wear and cratering. The FG (Finishing-General) chipbreaker utilizes a ground sharp edge to effectively manage chips during light finishing passes. With a 0.4mm corner radius, this insert minimizes vibration on slender workpieces while delivering the precision required for automotive and heavy industrial applications.
Key Features
Optimized for high-speed continuous cutting in cast iron, offering superior thermal stability compared to conventional gold grades.
A high-positive rake angle ensures low cutting forces, preventing work-hardening and maintaining workpiece integrity.
The ultra-hard Alumina coating prevents the abrasive particles in cast iron from degrading the cutting edge prematurely.

Global Industry Feedback
"Best in Class for GGG50"
We switched to TT5100 for our nodular iron housings. Tool life increased by 35% compared to our previous gold grade inserts.
— Cast Components Ltd (UK)"Hervorragende Standzeit"
High cutting speeds are no problem for this grade. The surface finish remains consistent from the first part to the last.
— Zerspanung Profis (Germany)"Stable and Reliable"
The FG chipbreaker is very effective. We have had no vibration issues on our internal finishing cycles.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Why is the TT5100 grade black instead of gold?
The black color indicates a specific CVD coating architecture optimized for thermal resistance in cast iron. It allows for much higher speeds without sacrificing tool life.
2. Is this insert suitable for interrupted cuts?
TT5100 is primarily for continuous cutting. For heavy interruptions in cast iron, consider a tougher grade like TT5080.

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.
