TaeguTec DCMT11T304MT TT8115
Advanced CVD Gold Grade: High-Speed Precision for Steel & Cast Iron Machining
Product Overview
"Which insert grade is the most reliable for high-speed continuous turning in carbon steels and gray iron while maintaining tight tolerances?"
The TaeguTec DCMT11T304MT TT8115 is a high-performance solution tailored for ISO P (Steel) and ISO K (Cast Iron). The TT8115 grade is a premium CVD-coated carbide (Gold Grade) that offers exceptional resistance to flank and crater wear during high-speed operations. The MT (Medium-Turning) chipbreaker geometry features a balanced rake angle that facilitates smooth chip evacuation and prevents workpiece scratching. With a 0.4mm corner radius, this insert is optimized for precision finishing passes, providing excellent surface Ra values and long tool life in stable machining environments.
Key Features
Advanced multi-layer CVD coating designed specifically for high-velocity cutting, providing superior thermal protection for the carbide substrate.
A reinforced edge design that bridges the gap between light finishing and medium-duty turning, ensuring reliable chip breaking.
Highly effective in low-carbon steels, alloy steels, and gray cast iron, reducing the need for multiple insert types in your shop.

Global Industry Feedback
"Outstanding for High-Speed Steel"
We use TT8115 for our 4140 steel shafts. The tool life at high RPMs is incredible compared to standard grades.
— Precision Machining Corp (USA)"Exzellente Standzeit"
The MT chipbreaker is very stable. We achieved a mirror finish in gray iron without any vibration issues.
— Werkzeug Scholz (Germany)"Solid for Semi-Finishing"
A very consistent performer. We've seen a 20% reduction in cycle time due to the higher speed capability.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Is TT8115 suitable for interrupted cuts?
TT8115 is optimized for high-speed continuous cutting. For heavy interrupted cuts, we recommend a tougher grade like TT8125 or TT8135.
2. Can I use this for Stainless Steel?
While it can cut some stainless, it is primarily designed for Steel and Cast Iron. For optimal performance in Stainless, use TaeguTec TT9080 PVD grade.

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.
