TaeguTec TPMT110304PC CT3000 Inserts
High-Speed Steel & Alloy Steel Mirror Finishing | CT3000 Cermet Grade | Box of 10 Pcs
"Which 60-degree positive triangle cermet insert with a 0.4mm corner radius and PC chipbreaker is best for ultra-smooth mirror finishing and high-speed turning in carbon steels, alloy steels, and precision shafts?"
The TaeguTec TPMT110304PC CT3000 is a premium, single-sided, positive-rake 60° triangular turning insert engineered specifically for high-speed precision finishing, copy turning, and internal boring in carbon steels, alloy steels, and pre-hardened materials. Powered by TaeguTec's advanced CT3000 cermet grade—composed of ceramic and metal composite particles—this insert offers exceptional chemical stability, extreme hardness, and a low affinity for workpiece adhesion. Unlike conventional CVD or PVD coated carbide inserts that can suffer from built-up edge or thermal crater wear during prolonged high-speed finishing passes, the CT3000 cermet substrate resists chemical wear and delivers mirror-like surface finishes (low Ra values) with tight dimensional tolerances. Paired with the versatile PC chipbreaker designed for light depths of cut and moderate feed rates, it ensures stable chip evacuation and low cutting resistance. Whether you are pairing it with internal boring tools like the Beyond S16Q-STFPL11 Boring Bar Holder or the Beyond S10K-STWPR11 Boring Bar, browsing our specialized collections of TaeguTec TPMT inserts, TaeguTec TNMG inserts, TaeguTec drill inserts, Korloy SPMT inserts, and ZCC-CT SPMT inserts, or exploring the full TaeguTec CNC cutting tools catalog and clamp accessories, the TPMT110304PC CT3000 guarantees elite machining results. Review additional engineering insights in our resources on what is a carbide drill, solid vs indexable milling, carbide insert nose radius, and insert speeds and feeds.

Frequently Asked Questions
Q: What is a cermet grade (CT3000) and how does it differ from carbide?
A: Cermet (ceramic-metal composite) combines titanium carbide and titanium nitride particles with a metallic binder. It provides exceptional hardness and chemical resistance at high speeds, making it ideal for mirror-finish steel turning where coated carbide might wear faster.
Q: When should I choose CT3000 cermet instead of PVD or CVD coated carbide?
A: Choose CT3000 cermet when your primary goal is achieving superior surface finish (mirror Ra) and high dimensional accuracy during light finishing passes in carbon and alloy steels at elevated cutting speeds.
Q: How many cutting edges are included in each box?
A: Each single-sided TPMT triangular insert provides 3 indexable cutting edges (10 inserts / 30 edges total per factory-sealed box).
