Accupro 75202770 Grooving Insert 0.1181 in ACP45M

Product Description

The ACCUPRO 75202770 is a GS-style grooving insert designed for external and internal grooving operations on CNC lathes and turning centers. It carries a cutting width of 0.1181 inches (3.000 mm) and a corner radius of 0.0079 inches (0.20 mm), making it suited to precise, narrow-groove work where dimensional accuracy is critical. The insert is manufactured in grade ACP45M with a PVD coating and a positive rake geometry, which reduces cutting forces and promotes clean chip formation. It belongs to the CI series and features a GPP chip breaker configuration. Licensed machinists and CNC operators install this insert as a direct replacement in compatible grooving toolholders.

This insert is intended for use in production turning environments where consistent groove width and corner geometry are required. The positive rake angle and GPP chip breaker support efficient chip evacuation in a range of workpiece materials. The 0.1181-inch cutting width is a common standard dimension across grooving toolholder systems that accept the GS insert style with a size code 30. It is applicable to both light finishing passes and general-purpose grooving in production or repair shop settings. The multi-use tool designation indicates compatibility across multiple holder configurations within the CI series.

Key Features

• Cutting width of 0.1181 inches (3.000 mm) for precise groove dimensioning
• ACP45M grade with PVD coating for wear resistance and extended tool life
• Positive rake geometry reduces cutting forces and improves surface finish
• GPP chip breaker supports controlled chip evacuation
• GS insert style, size code 30, CI series for broad holder compatibility
• Corner radius of 0.0079 inches (0.20 mm) for tight-tolerance groove profiles

Compatibility

Designed as an OEM-style replacement grooving insert for CNC lathe and turning center toolholders that accept GS-style inserts with size code 30 in the CI series.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down the machine and confirm the spindle is fully stopped before changing inserts. Seat the insert firmly using the appropriate clamp, screw, or self-grip holding method as specified by the toolholder manufacturer. Inspect the insert seat and clamp for damage before reinstalling, and verify cutting width and corner radius against the job drawing before resuming operation.
