Sandvik Coromant 5730487 Turning Insert 55 Diamond Carbide

Product Description

The SANDVIK COROMANT 5730487 is a solid carbide turning insert designed for precision machining of hard materials on CNC lathes and turning centers. Part of the CoroTurn 107 series, this insert features a 55-degree diamond shape (DCGW style) with a neutral hand orientation and a screw-in holding method. It carries manufacturer grade 7025, an uncoated bright finish, and a corner radius of 0.0156 inches (1/64 inch). The insert provides two cutting edges per unit, making it well suited for finishing and light turning passes where tight tolerances and surface finish quality are critical.

This insert is intended for turning applications on hard workpiece materials, classified under ISO material group H. The CoroTurn 107 series is commonly used in residential and industrial machine shops by CNC machinists and toolroom operators running external turning, facing, and light profiling operations. The DCGW geometry with the W chip breaker is optimized for controlled chip formation on hardened steels and similarly difficult materials where insert integrity and edge sharpness are the primary concerns.

Compatibility

Designed for use with CoroTurn 107 series toolholders that accept DCGW-style inserts with screw-in clamping. ISO code reference: DCGW11T304S01020F 7025. Intended for hard material turning applications in CNC turning and toolroom environments.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the cutting edge and seating surface for chips or contamination before each use.
