Sandvik Coromant 5755656 Turning Insert VBMT331-PM 5015

Product Description

The SANDVIK COROMANT 5755656 is a solid carbide turning insert in the VBMT style, designed for precision metal cutting on CNC and manual lathes. Manufactured under the CoroTurn 107 series, this insert carries grade 5015 and features an uncoated bright finish. It has a 35-degree diamond shape (Insert Shape Code V), a 3/8-inch inscribed circle, a 1/64-inch corner radius (0.0156 inches), and an overall insert length of 0.638 inches. With a neutral hand orientation and a PM chip breaker geometry, it is suited for stable turning operations with consistent chip control. Licensed machinists and CNC operators are the primary installers of this insert.

This turning insert is engineered primarily for steel (ISO material code P) and secondarily for cast iron (ISO material code K). It fits into screw-held VBMT toolholders and is well-suited for general-purpose external turning, profiling, and finishing passes on both production and job-shop lathes. The PM chip breaker geometry supports medium cutting conditions where reliable chip evacuation and edge stability are required. The ISO designation for this insert is VBMT 16 04 04-PM 5015, which can be used to verify compatibility with holder systems and reference charts.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Always power down and lock out the machine spindle before changing inserts. Seat the insert fully into the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the insert seat for chips or debris before installation to ensure proper seating and edge alignment.
