TaeguTec SCMT09T308-MT CT3000
Precision Cermet Technology: The Ultimate Solution for Mirror-Finish Steel Turning
Product Overview
"Which square insert should I use to achieve the best possible surface finish on steel parts while maintaining high cutting speeds?"
The TaeguTec SCMT09T308-MT CT3000 is specifically designed for high-speed finishing of ISO P (Steel). The CT3000 Cermet grade (Ceramic + Metal) provides a unique advantage over traditional carbide: it has low affinity for steel, which virtually eliminates built-up edge and produces a superior surface Ra value. The MT (Medium) chipbreaker features a sharp, positive rake angle that ensures clean chip shearing and stable evacuation. With its 0.8mm radius, this insert offers enhanced durability for high-precision semi-finishing tasks, making it an essential tool for automotive and aerospace components.
Key Features
Unmatched chemical stability and thermal resistance for high-speed precision finishing without the risk of oxidation wear.
Specifically engineered to prevent built-up edge, ensuring consistent dimensional accuracy and a high-quality aesthetic finish.
The Medium chipbreaker offers a wide range of chip control, making it versatile for both final finish and semi-finishing passes.

Choose TaeguTec for precision that makes your work shine.
Verified Global Feedback
"Amazing Finish"
We switched to the CT3000 for finishing our bearing housings. The surface finish is so good we were able to skip a grinding step. Highly recommended.
— Precision Components Inc. (USA)"Exzellente Oberflächengüte"
Outstanding performance on alloy steel. The MT geometry breaks chips perfectly even at very small feed rates. Very stable cermet grade.
— Müller Zerspanungstechnik (Germany)"Qualità Superiore"
Perfect for high-speed finishing. The dimensional stability over 500 parts was impressive. No built-up edge issues at all.
— Meccanica di Precisione (Italy)"Very Clean Cuts"
Very effective for dry machining steel parts. The tool life is quite long for finishing operations. Very satisfied with TaeguTec.
— Sato Precision Works (Japan)Frequently Asked Questions
1. Why use Cermet (CT3000) instead of Carbide?
Cermet has a higher chemical resistance and lower friction against steel, which prevents built-up edge (BUE) and results in a significantly better surface finish than carbide.
2. Can I use this for interrupted cutting?
Cermet is more brittle than carbide. While it can handle light vibrations, it is best suited for continuous finishing. For interrupted cuts, we suggest using a tough carbide grade like TT8125.

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.
