TaeguTec SNMG120408 TT7015
High-Speed Industrial Productivity: Advanced CVD Wear Resistance
Product Overview
"Which CNC insert provides the highest stability and longest tool life when performing high-speed turning on carbon steel and gray cast iron?"
The TaeguTec SNMG120408 TT7015 is the industrial answer for high-velocity machining. Targeted at ISO P (Steel) and ISO K (Cast Iron), this insert thrives where heat and abrasion typically cause failure. The TT7015 grade features a thick Al2O3 (Alumina) CVD coating that acts as a thermal shield, allowing for significantly higher surface speeds (m/min) compared to standard grades. The 0.8mm radius combined with a robust chipbreaker geometry ensures excellent chip evacuation during medium turning operations, preventing chip-nesting and workpiece damage.
Key Features
Thick Alumina coating provides superior crater wear resistance, making it ideal for continuous, high-speed cutting.
Double-sided square design offers 8 usable cutting edges, drastically reducing the cost-per-component in mass production.
Optimized for dry machining or high-pressure coolant environments, maintaining edge sharpness even under intense heat.

Verified Global Feedback
"Steel Production Beast"
We run these on 1045 steel at high speeds. The tool life is double what we were getting with our previous supplier. Highly recommended.
— Manufacturing Corp (USA)"Top für Gusseisen"
Outstanding performance in gray iron. Wear is very predictable, which is great for our automated production.
— CNC-Technik GmbH (Germany)"Qualità costante"
Dimensional stability is key for us. This insert holds tolerances over hundreds of parts with ease.
— Officina Meccanica (Italy)"Great at high speeds"
Very impressive Alumina coating. Handles the heat during dry machining very well.
— Sato Precision (Japan)Frequently Asked Questions
1. Is TT7015 suitable for interrupted cuts?
TT7015 is a high-hardness grade optimized for continuous high-speed turning. For heavy interruptions, consider the tougher TT8125 grade.
2. Can I use this for Stainless Steel?
While possible, it is not recommended. For Stainless Steel (ISO M), the PVD-coated TT5080 or TT8020 grades will provide much better results.

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.
