TaeguTec CNMG120404FG TT5100
High-Velocity Cast Iron Specialist: Precision Finishing with Advanced CVD Technology
Product Overview
"Which carbide insert grade offers the highest wear resistance and best surface finish during high-speed finishing of gray and ductile cast iron?"
The TaeguTec CNMG120404FG TT5100 is a high-precision 80° rhombic insert purpose-built for ISO K (Cast Iron) finishing. Utilizing the industry-leading TT5100 CVD (Chemical Vapor Deposition) grade, this tool features a thick, highly wear-resistant alumina coating optimized for abrasive materials. The FG (Finishing) chipbreaker geometry is designed with a sharp cutting edge and positive rake angle to minimize cutting forces and ensure exceptional chip evacuation, even at light depths of cut and high velocities.
Key Features
A specialized substrate combined with a thick Al2O3 layer designed to resist abrasive flank wear at high temperatures.
Optimized for finishing (FG), providing mirror-like surface Ra and preventing "bird-nesting" at low feed rates.
Superior coating adhesion ensures the edge stays intact during long finishing passes in mass production cycles.

Verified Global Feedback
"Mirror finish on GG25"
We use TT5100 for finishing gray iron pump bodies. The surface finish is better than anything else we've tried at 500m/min.
— Precision Foundry (Germany)"Exceptional Wear Resistance"
Replaced our standard grades with these FG breakers. Tool life increased by 40% on abrasive ductile iron parts.
— Manufacturing Corp. (USA)"Reliable for CNC Shops"
Very consistent. Maintaining tolerances across large batches is easy with the FG geometry.
— Tech Works (Japan)Frequently Asked Questions
1. Can I use TT5100 for Steel Turning (ISO P)?
No. TT5100 is a dedicated Cast Iron grade. For Steel, we recommend using the TT8125 or TT8115 grades for optimal performance.
2. What is the main benefit of the FG chipbreaker?
The FG breaker is specifically for finishing. It maintains exceptional surface Ra and provides better chip control at very light cutting depths.

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.
