TaeguTec DNMG150608MC TT8115
Reinforced 6.35mm Thickness: The High-Speed Specialist for Precision Steel Machining
Product Overview
"Which reinforced insert provides the maximum thermal stability for continuous high-speed turning in alloy steels?"
The TaeguTec DNMG150608MC TT8115 is a premium industrial tool designed for ISO P (Steel) materials. By utilizing the 1506 series (6.35mm thickness), this insert offers enhanced rigidity and vibration dampening over standard 4.76mm models. The TT8115 grade features a specialized CVD coating with a thick Alumina (Al2O3) layer, providing unparalleled resistance to crater wear during high-velocity operations. The MC (Medium Chipbreaker) geometry balances edge strength with chip control, ensuring smooth evacuation and mirror-like surface integrity on carbon, alloy, and tool steels.
Key Features
6.35mm profile offers superior mechanical support and thermal dissipation for stable high-heat cutting.
Thick Alumina CVD coating acts as a thermal shield, enabling higher Vc (cutting speeds) in continuous steel passes.
Optimized for medium-to-finishing depths, preventing bird-nesting and improving process reliability.

Verified Global Feedback
"Elite Surface Quality"
We use TT8115 for finishing large 4340 shafts. The speed we can run at is incredible, and the finish is like a mirror.
— Precision Dynamics (USA)"Hervorragende Standzeit"
Stable tool life even at very high temperatures. The 6.35mm thickness really helps with heat and vibration.
— Werkzeugbau Müller (Germany)"Produttività Elevata"
Outstanding for our high-volume production line. The MC chipbreaker is very consistent across carbon steel grades.
— Meccanica di Precisione (Italy)"Stable at High Velocity"
Very sharp and reliable. Performs exceptionally well in dry cutting on our CNC lathes.
— Industrial Tooling Corp (Japan)Frequently Asked Questions
1. What is the main difference between 1506 and 1504 inserts?
The 1506 designation indicates a 6.35mm thickness, whereas 1504 is 4.76mm. The thicker insert offers better mechanical strength and heat absorption.
2. Is TT8115 better than TT8125 for all steel parts?
Not necessarily. Choose TT8115 for continuous high-speed finishing. Use TT8125 if you have interruptions or vibrations in your process.

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.
