Accupro 75239749 Grooving Insert Gd 0.1575 in ACP30M

Product Description

The ACCUPRO 75239749 is a GD-style grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. It carries a cutting width of 0.1575 inches (4.000 mm) and a corner radius of 0.0787 inches (2.00 mm). The insert is manufactured to the ACP30M grade with a PVD coating and features a positive rake geometry, which reduces cutting forces and supports cleaner chip evacuation. A GPR chip breaker controls chip flow during grooving passes. Licensed machinists and CNC operators install this insert as a replacement unit in compatible CI-series toolholders.

This insert is suited for grooving applications in general machining environments, including light to moderate interrupted cuts in ferrous and non-ferrous materials where a positive rake and PVD coating provide wear resistance and edge stability. The GD insert style is compatible with clamp, screw, and self-grip holding methods, giving it flexibility across multiple toolholder configurations. It is a multi-use insert appropriate for production turning cells as well as job-shop environments requiring consistent groove width repeatability.

Compatibility

Designed for use with CI-series toolholders that accept GD-style grooving inserts with insert size code 24 and a 0.1575 inch cutting width.

Installation Notes

Installation should be performed by a qualified machinist with the machine in a full stop and locked-out condition before insert exchange. Seat the insert fully against the toolholder pocket and confirm the clamping mechanism is secure before resuming operation. Inspect the pocket for chips or debris prior to seating to prevent insert rocking and premature edge failure. Follow the toolholder manufacturer torque specifications for screw-retained configurations.
