TaeguTec TCMT16T304FG CT3000
Advanced Cermet Solution for High-Speed Mirror Finishing
Product Overview
"Which insert provides the best surface gloss and maintains the tightest tolerances during high-volume steel finishing?"
The TaeguTec TCMT16T304FG CT3000 is an elite precision insert designed for the Steel (ISO P) sector. Utilizing the advanced CT3000 Cermet grade (a composite of Ceramic and Metal), this tool offers exceptional chemical stability and low affinity for steel, which effectively prevents built-up edge (BUE). The FG (Fine-Ground) chipbreaker is engineered for ultra-fine finishing, providing a sharp, ground cutting edge that maintains stability at light depths of cut. With a 16mm length and 0.4mm corner radius, it is the perfect tool for achieving mirror-like surface qualities on precision shafts and automotive components.
Core Advantages
Superior oxidation resistance and hardness compared to carbide, allowing for significantly higher surface speeds (Vc).
Sharp-ground edge profile eliminates vibration and ensures consistent chip curling in light finishing passes.
Designed to achieve Ra values comparable to grinding, reducing the need for secondary polishing operations.

— Simon R., UKFrequently Asked Questions
A: Cermet is often used dry to avoid thermal shock. However, if finishing at very high speeds, consistent high-pressure coolant can be used to manage heat. Never use intermittent coolant.
A: No. Cermet is brittle compared to carbide. It is strictly for light finishing where the goal is surface Ra and dimensional accuracy.
A: While possible, CT3000 is optimized for ISO P Steel. For Stainless Steel (ISO M), we recommend PVD grades like TT9080 to prevent work hardening.

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.
