Taegutec Negative Turning Inserts
Double-Sided High-Strength Solutions for Maximum Metal Removal
Product Overview
"How can I reduce my cost-per-edge while maintaining high stability during heavy interrupted cuts in alloy steel?"
Taegutec Negative Turning Inserts are designed for high-power CNC machining where stability and economy are top priorities. Unlike positive inserts, negative inserts are double-sided, effectively doubling your cutting edges per insert. Featuring a 0° clearance angle, these tools offer a robust cross-section that absorbs heavy cutting forces and vibrations. Whether you are using the versatile CNMG, the profiling specialist DNMG, or the high-efficiency WNMG, Taegutec’s GoldRush coating technology ensures industry-leading heat resistance and surface finish.
Core Brand Advantages
- Double-Sided Economy: Up to 8 cutting edges (TNMG) or 6 edges (WNMG) to minimize tooling spend.
- Advanced Chip Control: Specialized -PC (Steel), -MT (Stainless), and -FG (Finishing) geometries for perfect swarf management.
- TT8100 & TT9100 Series: High-purity Al2O3 CVD coatings for superior tool life at high cutting speeds.
- RhinoRush Compatibility: Compact size options for high-stability machining in smaller CNC lathes.

Global User Reviews
★★★★★
"The WNMG TT8125 is the most cost-effective insert in our shop. 6 edges per insert and it handles dry cuts beautifully."
— Robert K., USA
★★★★★
"DNMG 150608 delivers a mirror finish on stainless with the MT chipbreaker. Faster cycle times than our previous supplier."
— Alessandro M., Italy
★★★★★
"Absolut stabil bei unterbrochenem Schnitt. Taegutec ist bei uns Standard."
— Dieter W., Germany
★★★★★
"非常に安定した品質。大量生産に欠かせません。"
— Kenji S., JapanFrequently Asked Questions
Q: Why choose negative inserts over positive inserts?
A: Negative inserts have double the edges and are much stronger due to their geometry. They are the preferred choice for heavy roughing and when machine rigidity is not an issue.
Q: Can I use CNMG for finishing?
A: Absolutely. By choosing a finishing chipbreaker like the -FG or -FA and a smaller nose radius (0.2 or 0.4mm), you can achieve excellent precision with a standard negative insert.
Material Tip: For stainless steel, prioritize the TT9030 PVD grade to minimize thermal cracking and adhesive wear on the cutting edge.
