Sandvik Coromant 5751859 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 5751859 is a solid carbide, uncoated turning insert in the TCGX style, part of the CoroTurn 107 series. Designed for precision external turning operations, it features a 60-degree triangular insert shape with three cutting edges, a 7-degree relief angle, and an AL chipbreaker geometry optimized for non-ferrous materials. With a 5/32-inch inscribed circle and a 1/64-inch corner radius, this insert delivers tight tolerances and sharp cutting action on aluminum and similar soft materials. It is held in place via a screw-clamping system and runs in a neutral hand orientation, making it straightforward to position in compatible toolholders.

This insert is intended for turning applications involving non-ferrous metals as the primary workpiece material, with secondary suitability for superalloys and titanium. The AL chipbreaker geometry is specifically developed for high-speed finishing and semi-finishing of aluminum and other non-ferrous alloys where chip control and surface finish are critical. Typical use cases include CNC turning centers in precision machining shops, production environments, and tool rooms. Each unit is sold individually but is subject to a minimum order quantity of 10 pieces per order.

Key Features

• Solid carbide construction with bright/uncoated finish for reduced built-up edge on non-ferrous materials
• AL chipbreaker geometry optimized for aluminum and non-ferrous metal turning
• 60-degree triangular shape with 3 cutting edges for extended tool life per insert
• 7-degree relief angle (TCGX style) for clearance and reduced cutting forces
• Screw-clamping insert holding method for secure, repeatable seating
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

This insert is compatible with CoroTurn 107 series toolholders designed for TCGX-style screw-on inserts. ISO code TCGX 06 T1 04-AL H10 should be used when cross-referencing with toolholder selection guides and compatibility charts.

Installation Notes

Installation is performed by a machinist or toolroom technician on a powered-down, fully stopped CNC lathe or turning center. Remove the existing insert, clean the insert pocket and seating surface, and seat the new insert firmly before tightening the clamping screw to the toolholder manufacturer's specified torque. Always verify insert orientation and chipbreaker direction before resuming cutting operations.
