Sandvik Coromant 5752070 Tcgt Turning Insert Grade 5015

Product Description

The SANDVIK COROMANT 5752070 is a solid carbide turning insert in TCGT style, designed for precision metal cutting on CNC lathes and manual turning centers. This triangular insert carries a 60-degree included angle, a 7-degree relief angle, and a 0.40 mm (1/64 inch) corner radius. The grade 5015 substrate is uncoated, making it well suited for finishing cuts on non-ferrous materials such as aluminum and copper alloys where a bright surface finish and sharp edge are priorities. The UM chip breaker geometry controls chip flow at light depths of cut and high surface speeds. Licensed machinists and CNC operators install this insert as part of routine tooling maintenance.

This insert fits screw-clamped toolholders designed for TCGT-style inserts with a 2.50 mm hole diameter. The 5015 uncoated carbide grade is commonly applied in high-speed finishing of aluminum, brass, and other soft non-ferrous materials where coated grades can cause built-up edge. Typical applications include OD turning, facing, and light profiling on production lathes in precision machining shops, aerospace component work, and general metalworking environments.

Key Features

• TCGT insert style with screw-clamping hole (2.50 mm hole diameter)
• 60-degree triangular shape provides three usable cutting edges per insert
• Grade 5015 solid carbide substrate, bright and uncoated for low-friction cutting of non-ferrous materials
• UM chip breaker geometry optimized for light finishing cuts and chip control at high speeds
• 7-degree relief angle (clearance code C) reduces flank wear in finishing operations
• ISO code TCGT 09 02 04-UM 5015 for cross-reference with standard toolholder catalogs

Compatibility

Designed as a direct-fit replacement for TCGT-style screw-clamp toolholders accepting a triangular insert with a 5.71 mm inscribed circle and a 2.50 mm mounting hole. Cross-references to ISO code TCGT 09 02 04-UM 5015.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque guidance for screw-clamp systems. Inspect the insert pocket and clamping screw for damage before seating a new insert. Ensure the machine spindle is fully stopped and the control is in an E-stop or lockout state before changing inserts. Do not exceed the insert manufacturer's recommended cutting parameters for grade 5015 in the material being machined.
