Sandvik Coromant 5752139 Turning Insert Tcmt H13A Coroturn 107

Product Description

The SANDVIK COROMANT 5752139 is a solid carbide turning insert designed for precision metal cutting in CNC and manual lathe applications. Carrying the TCMT insert style with a 60-degree triangular shape, this insert measures 10.74 mm in length with a 0.25-inch inscribed circle and a 0.40 mm (1/64 inch) corner radius. The H13A uncoated carbide grade delivers sharp, consistent edges suited for finishing and light-to-medium turning passes. The UM chip breaker geometry controls chip flow during continuous cuts, reducing buildup on the cutting edge. This insert belongs to the CoroTurn 107 series and is installed using a screw-type holding method.

The 5752139 is intended for turning steel and stainless steel workpieces in production and job-shop environments. It fits CoroTurn 107 toolholders designed for TCMT-style inserts with screw clamping. Typical applications include external turning, facing, and profiling on ferrous materials. The neutral hand orientation makes it adaptable across a range of toolholder configurations. Machinists and CNC operators working on P-class steel and M-class stainless steel will find this insert well-suited to finishing operations where edge sharpness and chip control are critical.

Installation Notes

This insert is installed and replaced by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamping screw to avoid edge chipping from improper seating. Do not exceed the maximum depth of cut listed in the technical specifications for this insert geometry.
