TaeguTec CCMT120408PC CT3000
Precision Finishing Specialist: Achieve Mirror Surfaces with Advanced Cermet Technology
Product Overview
"Which insert is the most reliable for achieving high-gloss surface finishes and maintaining long-term dimensional accuracy on steel components at high speeds?"
The TaeguTec CCMT120408PC CT3000 is an 80° rhombic positive insert engineered with CT3000 Cermet technology. Cermet, a hybrid of ceramic and metallic materials, offers superior chemical stability and resistance to built-up edge (BUE) compared to standard carbide. This specific model features the PC finishing chipbreaker and a reinforced 0.8mm (032) corner radius, providing the perfect balance between cutting edge sharpness and mechanical strength for high-speed finishing of Carbon Steel, Alloy Steel, and Ductile Iron.
Key Features
Exceptional resistance to oxidation and wear at high temperatures, ensuring long-lasting mirror-like finishes.
Sharp cutting edge designed specifically for low depths of cut, reducing radial forces and vibration.
Provides improved edge strength for finishing passes where higher feed rates or slight interruptions are present.

Verified Global Feedback
"Surface is like glass"
We switched to CT3000 for our finishing pass on 4140 steel. The gloss is unbelievable. The 0.8mm radius holds up perfectly.
— Machining Solutions Inc. (USA)"Top Qualität"
Consistent tool life across 400 parts. The PC chipbreaker makes clearing chips easy even at light DOC.
— Präzisionstechnik GmbH (Germany)"Very reliable"
Great for high-speed finishing. Dimensional accuracy is much better than our previous coated carbide inserts.
— Precision Works (Italy)Frequently Asked Questions
1. Is CT3000 suitable for dry machining?
Yes. Cermet has high chemical stability and performs exceptionally well in dry machining, which also helps avoid thermal shock.
2. Why use a 0.8mm radius for finishing?
The 0.8mm radius (032) provides a stronger edge than the 0.4mm version, allowing for slightly higher feed rates while maintaining a smooth surface finish.

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.
