TAEGUTEC CCMT120404MT CT3000 Uncoated Cermet Insert for High-Speed Finishing with 80° Rhombic Shape

The TAEGUTEC CCMT120404MT CT3000 is an 80° rhombic positive rake cermet turning insert from TAEGUTEC (South Korea). It is developed for high-speed finishing and light semi-finishing of carbon steel, alloy steel and low-alloy materials. Equipped with MT chipbreaker and premium CT3000 uncoated cermet grade, it delivers excellent surface finish, outstanding heat resistance and stable dimensional accuracy for continuous precision turning on CNC lathes.

• Insert Geometry: CCMT = 80° rhombic shape, 7° positive relief angle, M tolerance class with mounting hole
• Dimension Marking: 12 = inscribed circle 12.7 mm, 04 = insert thickness 4.76 mm, 04 = corner radius 0.4 mm
• MT Chipbreaker: Designed for general finishing, low cutting force and smooth chip flow
• CT3000 Grade: High-performance uncoated cermet, features high hardness and anti-built-up edge performance
• Sharp Cutting Edge: Precisely ground edge for superior surface quality of workpieces
• Wide Compatibility: Fits standard CCMT series turning tool holders for external turning, facing and boring

• Carbon steels (1045, S355, Q235, S45C) – primary application
• Alloy steels (4140, 42CrMo4, SCM440, HRC ＜ 42)
• Low-strength stainless steels (light finishing only)
• Grey cast iron (HT200, HT250, light cuts)

• High-speed external turning and facing
• Precision internal boring and profiling
• Light semi-finishing and fine finishing operations
• Mass production of standard mechanical components
• Dry turning (recommended) for stable machining performance

This cermet insert combines MT finishing geometry and professional CT3000 cermet substrate. It runs stably at high cutting speeds, effectively avoids built-up edge and maintains long tool life. With reliable Korean manufacturing technology, it is an ideal choice for high-efficiency and high-precision finishing in mass production.
