Original Korea TaeguTec SCMT120408PC TT9080 Golden PVD Coated Turning Insert for Medium Finishing with 0.8mm Nose Radius

Product Overview
The TaeguTec SCMT120408PC TT9080 is an original Korean positive square indexable turning insert under TaeguTec’s SCMT series, matched with versatile TT9080 PVD coating grade. It features PC medium-finish chipbreaker geometry, 7° positive back relief angle and 0.8mm nose radius, adopting single-sided 4 usable cutting edges. Equipped with TiAlN-TiN composite golden PVD coating, this insert balances low cutting resistance, anti-built-up edge and wear resistance, specialized for medium turning & finishing of carbon steel, alloy steel, austenitic stainless steel and low-hardness heat-resistant alloys. It fits standard SCLCR/SCLCN/SCMCN square tool holders for external turning, internal boring and facing operations on CNC lathes, widely used in auto parts, hydraulic fittings and general precision metal mass production.
