Accupro 75216143 Grooving Insert 0.1575 in ACP45M

Product Description

The ACCUPRO 75216143 is a GD-style grooving insert designed for precision grooving operations on CNC turning centers and lathes. Built to the CI series, it carries a manufacturer grade of ACP45M with a PVD coating for wear resistance and thermal stability. The cutting width measures 0.1575 inches (4.000 mm), and the corner radius is 0.0118 inches (0.30 mm). The positive rake geometry and GPP chip breaker work together to promote clean chip evacuation and reduce cutting forces. This insert is sold individually and is intended for use by machinists and tooling technicians in production and job-shop environments.

The 75216143 is suited for grooving, parting, and related turning operations on ferrous and non-ferrous workpiece materials. Its size code 24 designation fits compatible CI-series grooving toolholders. The positive rake design makes it appropriate for finishing and medium-duty grooving passes where surface finish and dimensional accuracy are priorities. It is a multi-use insert, supporting a lead angle of 0.000 degrees. Typical applications include O-ring grooves, snap-ring grooves, and face grooving on turned components in general manufacturing and precision machining operations.
