Sandvik Coromant 5752873 Turning Insert TCMW21.51 CB20

Product Description

The SANDVIK COROMANT 5752873 is a solid carbide, uncoated turning insert in the TCMW21.51 S0320E CB20 configuration, part of the CoroTurn 107 series. 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).

This 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.
