TaeguTec CNMG160612MT TT5100
Optimized for Cast Iron: High-Speed CVD Grade for Maximum Productivity
Product Overview
"Which insert grade provides the longest tool life and best wear resistance when turning grey or ductile cast iron at high cutting speeds?"
The TaeguTec CNMG160612MT TT5100 is the ultimate solution for ISO K (Cast Iron) applications. The TT5100 CVD grade features a thick Al2O3 coating combined with a high-hardness substrate, specifically engineered to withstand the abrasive nature of cast iron. The MT (Medium-Tough) chipbreaker geometry reduces cutting forces while maintaining edge integrity, making it ideal for stable roughing to semi-finishing operations on CNC lathes.
Key Features
A thick, multi-layered alumina coating provides exceptional heat shield properties and crater wear resistance.
The larger insert body allows for deeper cuts and higher stability in heavy-duty machining cycles.
A versatile breaker that handles chips perfectly in both continuous and slightly interrupted iron cuts.

Verified Global Feedback
"Amazing Wear Resistance"
We turn 500 grey iron brake drums daily. The TT5100 grade consistently outlasts competitors by 25%, maintaining tolerance effortlessly.
— Automotive Spares (Italy)"Perfect for GG25"
Finally found an insert that doesn't crater at high speeds. The CNMG 16 size provides incredible stability on our CNC lathes.
— Machine Works Ltd (United Kingdom)"Reliable and Fast"
Great chip control with the MT breaker. We use it for semi-finishing ductile iron housings. Very dependable.
— Precision Foundry (USA)Frequently Asked Questions
1. Can I use TT5100 for Steel machining?
No, TT5100 is strictly optimized for ISO K (Cast Iron). For Steel (ISO P), we recommend using grades like TT8125 or TT8115.
2. What is the benefit of the 1.2mm radius?
The 1.2mm corner radius provides a much stronger cutting edge, allowing for higher feed rates and better heat dissipation compared to smaller radii.

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.
