Sandvik Coromant 5752149 Turning Insert Tcgt 1125

Product Description

The SANDVIK COROMANT 5752149 is a solid carbide turning insert in the TCGT 11 02 08-UM 1125 designation, part of the CoroTurn 107 series. It features a 60-degree triangular shape with a neutral hand orientation and a 1/32 inch (0.0313 inch) corner radius. The insert is coated with TiAlN and AlCr2O3 via a PVD process, making it well suited for finishing and semi-finishing operations on steel and a range of secondary workpiece materials. With three cutting edges and a screw-type holding method, it delivers consistent performance in precision turning applications. Licensed machinists and CNC lathe operators working in job shops, production environments, or toolrooms are the primary users.

This insert is designed for use in external and internal turning operations where tight tolerances and fine surface finishes are required. The UM chip breaker geometry supports light to moderate depth-of-cut applications on steel, stainless steel, non-ferrous metals, superalloys, and titanium. Its 1/4 inch inscribed circle and compact insert length of 0.3913 inches make it appropriate for smaller toolholders and precision turning work. It fits CoroTurn 107 compatible toolholders that accept TCGT-style inserts with a screw clamping system and a G tolerance, C clearance code configuration.

Key Features

• TiAlN and AlCr2O3 dual-layer PVD coating for wear resistance on steel and stainless steel
• 60-degree triangular insert shape with three usable cutting edges for extended tool life per insert
• UM chip breaker geometry optimized for light to moderate finishing cuts
• Neutral hand orientation for flexible right- or left-hand toolholder compatibility
• Screw-type insert holding method provides secure clamping and repeatable indexing
• G tolerance and C clearance code for precise fit in compatible CoroTurn 107 toolholders

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept TCGT-style inserts with a screw clamping method, G tolerance, and C clearance code. Compatible with primary workpiece material code P (steel) and secondary material codes M (stainless steel), N (non-ferrous metal), S (superalloy), and P (titanium) as specified in the manufacturer data.

Installation Notes

Insert indexing and replacement should be performed with the machine in a full stop and all power isolated from the spindle. Use the correct Torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw — do not over-torque, as this can fracture the insert. Inspect the toolholder pocket for chips or wear before seating a new insert. This work is typically performed by a CNC machinist or toolroom technician following shop floor safety procedures.
