Sandvik Coromant 5767783 Turning Insert 55 Diamond 7015

Product Description

The SANDVIK COROMANT 5767783 is a solid carbide turning insert with a titanium nitride (TiN) coating, designed for precision metal turning operations on CNC lathes and turning centers. This insert follows the DCGW style with a 55-degree diamond shape, grade 7015 carbide substrate, and a W-style chip breaker geometry. It measures 0.1142 inches in length with a 3/8-inch inscribed circle and a 1/64-inch corner radius. The screw-on holding method and G-tolerance classification make this insert well-suited for close-tolerance finishing passes where dimensional consistency and surface finish are critical.

This insert is intended for finish turning applications in ferrous and non-ferrous materials where a sharp edge geometry and TiN coating are appropriate for the workpiece material and cutting conditions. The 55-degree diamond insert shape provides a relatively acute cutting geometry suited to profiling and finish turning. It is typically installed by machinists and CNC operators in production and job shop environments. The ISO designation for this insert is DCGW11T304S01530F 7015, which can be used for cross-referencing with compatible toolholders per standard DCGW seating specifications.

Key Features

• 55-degree diamond insert shape (DCGW style) for profiling and finish turning applications
• Grade 7015 solid carbide substrate with titanium nitride (TiN) coating for wear resistance
• W-style chip breaker geometry for controlled chip formation during finishing cuts
• Screw-on (hole) holding method with 0.1732-inch hole diameter for secure seating in compatible toolholders
• G-tolerance classification supports consistent insert indexing and repeatable part dimensions
• 1/64-inch corner radius minimizes tool pressure while maintaining edge strength

Compatibility

Designed for use in DCGW-style screw-on turning toolholders with a clearance code C seating. Compatible toolholders must accept a 55-degree diamond insert with a 3/8-inch inscribed circle, 5/32-inch insert thickness, and a 0.1732-inch screw hole diameter. The ISO code DCGW11T304S01530F 7015 can be used to identify compatible holder designations per ISO turning insert standards.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Before indexing or replacing inserts, the machine spindle must be fully stopped and the program placed in feed hold or estop. Use the correct torque screwdriver or Torx key specified by the toolholder manufacturer when seating the clamping screw — do not overtighten, as this can fracture the insert. Inspect the toolholder seat and shim for debris or damage before seating the new insert to ensure proper contact and alignment.
