Sandvik Coromant 5730683 Turning Insert Dcmt 55 Diamond

Product Description

The SANDVIK COROMANT 5730683 is a solid carbide, uncoated turning insert in the DCMT style, part of the CoroTurn 107 series. It features a 55-degree diamond insert shape with a neutral hand orientation and a 7-degree relief angle. The inscribed circle measures 3/8 inch (0.3750 inch decimal), and the corner radius is 1/64 inch (0.0156 inch decimal). With two cutting edges and a KM chip breaker geometry, this insert is designed for precision turning operations on CNC lathes and is installed by machinists and toolroom professionals working in production or job-shop environments.

This insert is suited for turning cast iron as its primary workpiece material, with non-ferrous metals as a secondary application. The CoroTurn 107 series is designed for internal and external turning where a screw-held, positive-geometry insert is required. The KM chip breaker geometry supports controlled chip formation across a range of feed rates and depths of cut. Typical installations include finishing and semi-finishing passes on CNC turning centers where dimensional accuracy and surface finish are critical.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket and torque the clamping screw to the toolholder specification using a calibrated torx or hex key. Inspect the insert pocket for wear or damage before each insert change to ensure proper seating and edge repeatability.
