It features a 60-degree triangular insert shape with a neutral hand orientation and a 7-degree relief angle. Designed for single-edge cutting operations, this insert targets hard materials (ISO material code H), making it suitable for demanding turning applications where edge integrity and dimensional consistency are critical. Installation is performed by machinists and CNC operators using the screw-holding method. The inscribed circle measures 0.25 inches and the corner radius is 0.0156 inches (1\/64 inch).\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in external turning applications on hard workpiece materials in precision machining environments, including production shops and tool rooms. It fits CoroTurn 107 toolholders that accept TCMW-style inserts with a screw-clamp holding method. The W chip breaker geometry and bright uncoated carbide grade CB20 make it well suited for finishing and semi-finishing passes on hardened steels and similar hard materials. Each package contains one insert; the minimum order quantity is 5 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide CB20 grade with bright uncoated finish for hard material turning\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape (TCMW style) with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eW chip breaker geometry for controlled chip flow on hard materials\u003c\/li\u003e\n\u003cli\u003eScrew-holding method provides secure, repeatable seating in CoroTurn 107 toolholders\u003c\/li\u003e\n\u003cli\u003eSingle cutting edge design for precision, consistent performance\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle and tight tolerance code M for accurate fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroTurn 107 series toolholders accepting TCMW-style screw-held inserts.
