Accupro 75212688 Grooving Insert Ci Style 3mm ACP35K

Product Description

The ACCUPRO 75212688 is a CI-style grooving insert engineered for precision external and internal grooving operations on CNC turning centers and lathes. With a cutting width of 0.1181 inches (3.000 mm) and a corner radius of 0.0118 inches (0.30 mm), this insert delivers consistent groove geometry in ferrous and non-ferrous materials. The ACP35K manufacturer grade features a CVD coating for improved wear resistance and thermal stability at elevated cutting speeds. A positive rake geometry reduces cutting forces, while the GUT chip breaker promotes reliable chip evacuation in continuous and interrupted grooving passes.

This insert is suited for production turning environments where tight groove tolerances and repeatable surface finish are required. Typical applications include snap-ring grooves, undercuts, and thread-relief grooves on shafts, flanges, and bores. The CI series designation indicates compatibility with CI-style grooving toolholders. It is sold individually but must be ordered in multiples of 10, making it appropriate for stocking in high-volume shops. Licensed machinists and CNC operators performing turning operations are the primary users.

Key Features

• Compatible with clamp, screw, and self-grip insert holding methods
• Multi-use tool designation supports varied grooving and parting applications

Compatibility

Designed for use with CI-style grooving toolholders accepting Size Code 30 inserts. Verify toolholder manufacturer specifications before installation to confirm proper seating and clamping.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is locked out before changing inserts. Seat the insert fully in the pocket and secure using the appropriate clamp, screw, or self-grip method per the toolholder manufacturer instructions. Inspect the insert pocket for debris or wear before installation to maintain accurate tool geometry.
