Sandvik Coromant 5723343 Turning Insert CCMT32.51-KM H13A

Product Description

The SANDVIK COROMANT 5723343 is a solid carbide, uncoated turning insert in the CoroTurn 107 series. Designated by ANSI code CCMT32.51 and ISO code CCMT09T304, it features an 80-degree diamond (rhombic) shape with a positive side clearance and neutral hand orientation. The insert measures 0.365 inches in length with a 3/8-inch (0.375 inch) inscribed circle and a 1/64-inch (0.0156 inch) corner radius. It is screw-held and designed for two cutting edges per insert. The H13A grade delivers high wear resistance with moderate toughness, making it well-suited for roughing and medium machining operations on cast iron, aluminum, non-ferrous metals, and special or super alloys. Licensed machinists and CNC operators install this insert in lathe and turning center toolholders.

This insert is intended for external and internal turning applications where uncoated carbide grade H13A performance is required. The KM chip breaker geometry is rated for roughing and medium machining passes. Primary workpiece material classifications covered include cast iron (K), aluminum and non-ferrous metals (N), and special or super alloys (S), making this insert versatile across a range of production and job-shop turning setups. It fits CoroTurn 107 compatible toolholders designed for CCMT-style inserts.

Key Features

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down or lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert seat and screw threads for wear or contamination before mounting a new insert.
