TaeguTec SNMG120408-MT CT3000
Mirror Finish Specialist: Uncoated Cermet for High-Velocity Steel Finishing
Product Overview
"Which CNC insert should I use to achieve a high-gloss surface finish on carbon steel while maintaining tight dimensional tolerances at high speeds?"
The TaeguTec SNMG120408-MT CT3000 is the industrial answer to high-precision finishing. Utilizing the CT3000 Cermet grade, this insert provides superior oxidation resistance and low affinity for workpiece materials, virtually eliminating Built-Up Edge (BUE). The MT (Medium-Tolerance) chipbreaker is specifically designed for medium turning and finishing, featuring a geometry that ensures excellent chip evacuation even at low depths of cut. When your application demands aesthetic excellence and micron-level accuracy in Steel (ISO P), this cermet solution outperforms traditional carbide.
Key Features
A titanium-based composite that maintains a sharp edge longer than carbide in finishing, resulting in "mirror" surfaces.
Balanced chip control for a wide range of feed rates, specifically optimized for smooth chip breaking in steel finishing.
Allows for significantly higher cutting speeds (Vc) than carbide, increasing overall workshop productivity.

- Finish turning of high-tensile fasteners and precision spacers.
- General-purpose finishing of carbon and alloy steels under stable conditions.
Why Choose TaeguTec Cermet?
TaeguTec is at the forefront of Cermet technology. The CT3000 grade is specifically developed for the modern CNC shop that values both time and quality. Cermet inserts maintain their cutting edge sharpness much longer than coated carbide when performing light finishing cuts, which prevents dimensional "drift" over long production runs. By choosing our SNMG120408-MT CT3000, you are reducing tool change frequency and eliminating costly polishing or grinding steps. Invest in TaeguTec for precision that pays for itself.
Verified Global Feedback
"Mirror Surface"
We use CT3000 on low-carbon steel shafts. The finish is so good we were able to skip the grinding process entirely. Saved us hours.
— Precision Machining Co. (USA)"Hervorragende Maßhaltigkeit"
Outstanding dimensional stability. We run 500 parts without needing an offset. The MT chipbreaker works perfectly at 0.2mm depth.
— Drehtechnik Weber (Germany)"Ottima qualità"
Exceptional resistance to BUE. On gummy steels, this is the only insert that gives us a consistent finish.
— Meccanica di Alta Precisione (Italy)"Fast and Clean"
High cutting speeds are not a problem for this cermet. Clean chips and perfect Ra values every time.
— Kanto Precision (Japan)Frequently Asked Questions
1. Can I use CT3000 for interrupted cuts?
Cermet is more brittle than carbide. While CT3000 is quite tough, it is best used for continuous finishing. For interrupted cuts, we recommend a tough CVD carbide grade like TT8125.
2. Does this insert require coolant?
Cermet can be run dry due to its high thermal stability, but for the best surface finish and dimensional control, constant and high-pressure coolant is recommended.

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.
