TaeguTec TNMG 160408 MT CT3000
Professional High-Speed Cermet Insert for Superior Surface Finishing
Product Overview
"Which turning insert provides the best surface finish on steel while maintaining edge strength for semi-finishing cycles?"
The TaeguTec TNMG 160408 MT CT3000 is a high-performance Cermet insert engineered for CNC professionals who refuse to compromise on surface aesthetics. Unlike standard carbide, the CT3000 grade (Ceramic + Metal) offers exceptional chemical stability, effectively preventing the Built-Up Edge (BUE) that ruins surface Ra values. The MT Chipbreaker and 0.8mm radius provide the perfect geometry for stable chip evacuation in medium-to-finish turning applications on ISO P (Carbon/Alloy Steel). Use this insert to achieve a "mirror finish" and eliminate the need for costly secondary grinding.
Core Performance Features
Superior resistance to oxidation and crater wear, optimized for ultra-high cutting speeds in finishing.
Enhanced edge strength (08) for higher feed rates without sacrificing the legendary Cermet finish.
Triangular negative geometry providing 6 stable cutting edges for maximum ROI per part.

Machinist Feedback
"Switched from carbide to CT3000 for our steel gear finishing. The Ra value is perfect."
— Robert K., USA"Beste Oberflächengüte, die wir je hatten. CT3000 hält die Toleranz über lange Serien."
— Hans G., Germany"Eccellente finitura superficiale. Risparmiamo tempo eliminando la lucidatura."
— Paolo V., Italy"Very consistent performance at 300m/min. Great for mass production finishing."
— Tanaka S., JapanFrequently Asked Questions
A: Cermet is brittle. It is highly recommended for continuous cuts only. For interruptions, use a carbide grade like TT8125.
A: Cermet works best dry or with high-pressure constant coolant. Avoid intermittent coolant as it causes thermal cracking.
A: For finishing, we recommend an Ap between 0.2mm and 1.5mm for the 0.8 radius.

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.
