TaeguTec DCMT11T304MT CT3000
Elite Cermet Technology: Achieving Mirror-Like Surface Finishes in Steel
Product Overview
"Which insert grade is most effective for high-gloss finishing and semi-finishing in carbon and alloy steels without the need for secondary grinding?"
The TaeguTec DCMT11T304MT CT3000 is the ultimate solution for ISO P (Steel) precision turning. The CT3000 Cermet grade (Ceramic + Metal) provides significantly higher thermal stability than tungsten carbide, allowing it to withstand high cutting temperatures while resisting built-up edge (BUE). The MT (Medium-Turning) chipbreaker features a versatile geometry that bridges the gap between light finishing and semi-roughing, ensuring controlled chip breaking and preventing long, stringy chips that can damage the workpiece surface. With a 0.4mm corner radius, this insert provides the perfect balance of edge precision and toughness for intricate profile turning.
Key Features
A micro-grain cermet structure that offers incredible hardness and high-temperature chemical stability for a superior surface gloss.
Designed for semi-finishing applications, the MT breaker provides reliable chip control at moderate depths of cut and feed rates.
Cermet's low affinity for steel prevents workpiece welding, ensuring sub-micron surface Ra values and high dimensional accuracy.

Global Industry Feedback
"Eliminated Grinding"
The CT3000 cermet finish is so good we were able to eliminate the secondary grinding step on our shaft production. Incredible results.
— Precision Dynamics (USA)"Perfekte Oberfläche"
Super stable chip control with the MT breaker. The dimensions don't drift at all even after hundreds of parts.
— Werkzeug Technik (Germany)"Solid Cermet Performer"
Very clean cuts in alloy steel. The 0.4mm radius is perfect for fine detailing. Highly recommended for finish passes.
— Precisione Meccanica (Italy)Frequently Asked Questions
1. Is Cermet better than Carbide for all steel turning?
Cermet is superior for high-speed finishing because it resists chemical wear and heat better. However, for heavy roughing or interrupted cuts, Tungsten Carbide is tougher and more durable.
2. Can I use the MT breaker for light finishing?
Yes. The MT breaker is an all-rounder. While the FG is specifically for ultra-light finishing, the MT handles both finishing and semi-finishing with great stability.

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.
