Sandvik Coromant 5749740 Turning Insert 1/2 in Ic Carbide

Product Description

The SANDVIK COROMANT 5749740 is a solid carbide, uncoated turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a square insert shape with a 90-degree included angle, a 1/2-inch inscribed circle, and a 3/64-inch (0.0469-inch) corner radius. The insert thickness is 5/16 inch (0.3125 inch) and the insert length is approximately 0.4528 inch. Manufactured to ISO code SNGN120712E in grade 6060, this bright-finish carbide insert is suited for applications where coating is not required or where a sharp, uncoated cutting edge is preferred for material adhesion control.

This insert is used in turning operations on manual or CNC lathes across industrial metalworking environments. Its SNGN insert style, square shape, and N clearance code (0-degree relief angle) make it appropriate for general turning, facing, and light roughing passes. The clamp-style holding method requires a compatible toolholder designed for SNGN-style inserts. Typical users are machinists and toolroom operators working with ferrous and non-ferrous materials where an uncoated grade 6060 carbide edge delivers consistent performance.

Key Features

• Solid carbide grade 6060, bright uncoated finish for sharp cutting edge retention
• Square insert shape (S) with 90-degree included angle and SNGN insert style
• 1/2-inch inscribed circle (12.70 mm) for stable clamping and consistent depth of cut
• 3/64-inch corner radius (1.19 mm / 0.0469 inch) for controlled surface finish
• 5/16-inch insert thickness (7.94 mm) provides edge strength under cutting loads
• Clamp-style holding method compatible with standard SNGN toolholders

Compatibility

Designed as an OEM-style replacement turning insert for toolholders accepting SNGN-style square carbide inserts with a 1/2-inch inscribed circle and clamp-style retention.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw for the toolholder to secure the insert without cracking the carbide. Follow the toolholder manufacturer guidelines and applicable shop safety procedures when handling carbide inserts, as edges are extremely sharp.
