Accupro 75216135 Grooving Insert Ci Style ACP45M

Product Description

The ACCUPRO 75216135 is a CI-style grooving insert designed for precision grooving operations on CNC lathes and turning centers. Built to insert size code 24, it delivers a cutting width of 0.1575 inches (4.000 mm) and a corner radius of 0.0157 inches (0.40 mm). The insert is manufactured in grade ACP45M with a PVD coating and features a positive rake geometry paired with a GUT chip breaker for controlled chip evacuation during grooving passes. It is suited for machinists and toolroom professionals requiring consistent dimensional accuracy in groove profiles.

This insert is intended for external and internal grooving applications where a 4.000 mm cutting width is required. The CI series design is compatible with clamp, screw, and self-grip holding methods, offering flexibility across multiple toolholder configurations. It is a multi-use insert appropriate for a range of workpiece materials where PVD-coated carbide grades perform reliably, including steels and cast irons in production and job-shop turning environments.

Compatibility

Designed as a CI-series grooving insert compatible with toolholders accepting clamp, screw, or self-grip insert retention methods sized for insert size code 24.

Installation Notes

Installation should be performed by a qualified machinist with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Seat the insert firmly in the toolholder pocket and verify the holding method is secure before resuming operation. Inspect the insert seating surface and pocket for chips or debris before installation, as contamination can affect insert positioning and groove accuracy. Follow the toolholder manufacturer guidelines for the specific clamp or screw torque appropriate to the holder design.
