Accupro 75233999 Grooving Insert Ci Style ACP45M Grade

Product Description

The ACCUPRO 75233999 is a CI-style grooving insert designed for precision grooving operations on CNC lathes and turning centers. It features a cutting width of 0.0787 inches (2.000 mm) and a corner radius of 0.0079 inches (0.20 mm), making it suited for tight-tolerance groove profiles. Manufactured to grade ACP45M with a PVD coating and positive rake geometry, this insert delivers controlled chip formation and extended tool life in steel and alloy applications. The GUT chip breaker promotes efficient chip evacuation during grooving passes. Machinists and CNC operators in production and job-shop environments are the primary users.

This insert is used in external and internal grooving, parting, and profiling operations on turning equipment. The CI series design is compatible with CI-style insert holders and tooling systems that accept size 20 inserts. The positive rake angle reduces cutting forces, which benefits applications on smaller lathes or when machining thin-walled workpieces. The multi-use designation indicates the insert is suitable across a range of grooving and turning scenarios beyond single-purpose parting cuts.

Key Features

• Cutting width of 0.0787 inches (2.000 mm) for precise groove sizing
• Corner radius of 0.0079 inches (0.20 mm) for fine-detail groove profiles
• ACP45M grade with PVD coating for wear resistance and extended edge life
• Positive rake geometry reduces cutting forces and tool pressure
• GUT chip breaker promotes consistent chip control during grooving passes
• Compatible with clamp, screw, and self-grip insert holding methods

Compatibility

Designed as an OEM-style replacement insert for CI-style grooving toolholders and systems accepting size 20 inserts with clamp, screw, or self-grip holding methods.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque driver for screw-lock or clamp-style holders to ensure the insert is fully seated without rocking. Inspect the insert pocket and clamping surfaces for chips or debris before installation to avoid seating errors that can cause premature edge failure.
