TaeguTec TDT 4E-0.4 TT5100
Specialized 4.0mm CVD Solution for High-Speed Turning and Grooving in Cast Iron
Product Overview
"Which 4mm multi-function insert provides the longest tool life when high-speed turning abrasive Gray and Ductile Iron?"
The TaeguTec TDT 4E-0.4 TT5100 is a high-performance multi-directional tool designed for the specific challenges of Cast Iron (ISO K) machining. While universal grades often fail due to the abrasive nature of carbon flakes, the TT5100 grade utilizes a thick CVD coating that provides a massive thermal barrier and extreme hardness. The 4E geometry is a neutral, reinforced design that allows the tool to transition seamlessly from radial grooving to longitudinal turning. With a 0.4mm corner radius, it maintains edge strength under heavy loads while delivering the precision required for complex profiling of engine components, pulleys, and housings.
Core Advantages
The TT5100 grade offers superior abrasive wear resistance, allowing for much higher cutting speeds in Gray and Nodular iron compared to PVD grades.
Built for the T-Turn system, the insert handles significant side-loading forces during axial turning and profiling without deflection.
The 4E chipbreaker is designed to manage the short, brittle chips typical of cast iron, preventing dust buildup and ensuring a clean work environment.

"Amazing tool life on G25 gray iron. We doubled our cutting speed compared to our previous PVD grade."
— Robert T., USA"Der TT5100 ist perfekt für die Serienfertigung von Bremstrommeln. Sehr stabil."
— Hans B., Germany"Ottima resistenza all'abrasione sulla ghisa sferoidale. Consigliatissimo."
— Luca F., Italy"Consistent wear patterns. Makes it easy to predict tool changes in our lights-out shifts."
— Sato Y., JapanFrequently Asked Questions
A: No. TT5100 is optimized for Cast Iron. For Steel turning and grooving, the TT9080 or TT7220 grades are much better suited to prevent crater wear.
A: Yes, if paired with a T-Turn internal boring bar of the correct seat size (4), this insert is excellent for internal grooving and profiling.
A: CVD coatings are thicker and adhere better to the carbide substrate under the high-temperature abrasive conditions found in cast iron machining, resulting in significantly longer tool life.

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.
