Sandvik Coromant 5730448 Turning Insert Dcgt 1125 Carbide

Product Description

The SANDVIK COROMANT 5730448 is a solid carbide turning insert from the CoroTurn 107 series, designed for precision external turning and boring operations on CNC lathes and turning centers. This DCGT-style insert features a 55-degree diamond shape, a 3/8-inch inscribed circle, and a neutral hand orientation. The dual-layer TiAlN and AlCr2O3 PVD coating in manufacturer grade 1125 delivers thermal resistance and wear performance suited to finishing and semi-finishing cuts on steel and related materials. The UM chip breaker geometry controls chip evacuation in light to medium cutting conditions.

This insert is intended for use in the CoroTurn 107 insert series and is suited to external turning, profiling, and light boring operations. Primary workpiece material is steel, with secondary suitability for stainless steel, non-ferrous metals, superalloys, and titanium. The screw-held, countersunk hole design (ISO code DCGT 11 T3 01-UM 1125) seats into compatible 107-series toolholders. Applications span general metalworking shops, aerospace component machining, and precision turning of complex profiles where tight tolerances and consistent surface finish are required.

Key Features

• 55-degree diamond insert shape with DCGT geometry and 7-degree relief angle for clearance in profiling cuts
• PVD-applied TiAlN and AlCr2O3 dual-layer coating in grade 1125 for wear resistance on steel and superalloys
• UM chip breaker optimized for light to medium depth of cut and controlled chip formation
• 0.10 mm (0.0039 inch) corner radius for tight-tolerance finishing and fine surface finish
• Screw-held mounting with countersunk hole, compatible with CoroTurn 107 series toolholders
• Two cutting edges per insert for extended tool economy

Compatibility

Designed for use with CoroTurn 107 series toolholders accepting DCGT-style inserts with a 3/8-inch inscribed circle. ISO code DCGT 11 T3 01-UM 1125 should be cross-referenced against toolholder specifications to confirm seat compatibility before installation.

Installation Notes

Installation is performed by machining professionals on powered-off and locked-out CNC turning equipment. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer torque specification. Inspect the insert pocket and locating surfaces for chips or wear before seating a new insert. Never use a worn or chipped insert, as edge damage transfers directly to workpiece surface quality and dimensional accuracy.
