Accupro 75240721 Grooving Insert Gd ACP35K 2mm

Product Description

The ACCUPRO 75240721 is a GD-style grooving insert engineered for precision groove turning and parting operations on CNC lathes and turning centers. Manufactured to the ACP35K grade with a CVD coating, this insert delivers consistent cutting performance in steel and other ferrous materials. The cutting width measures 0.0787 inches (2.000mm) with a corner radius of 0.0079 inches (0.20mm), making it well suited for tight-tolerance groove profiles. A positive rake geometry reduces cutting forces and chip load on the workpiece. Machining professionals and CNC operators install and index these inserts as part of routine tooling maintenance on production turning equipment.

This insert is used in groove turning applications on both light-duty and production CNC lathes. The GD insert style is compatible with CI-series toolholders that accept clamp, screw, or self-grip holding methods. The GUP chip breaker geometry promotes controlled chip evacuation during grooving passes, which is critical in high-volume turning environments where chip interference can cause surface defects or tool damage. Typical applications include external and internal groove profiles, undercuts, and parting operations in job-shop and production settings.

Key Features

• CVD coating provides wear resistance and extended tool life in ferrous cutting applications
• Positive rake geometry reduces cutting forces and workpiece deflection
• GUP chip breaker promotes controlled chip formation and evacuation
• Compatible with clamp, screw, and self-grip insert holding methods
• 0.0079-inch (0.20mm) corner radius supports tight-tolerance groove profiles
• Multi-use tool designation allows use across a range of groove turning operations

Compatibility

Designed for use with CI-series grooving toolholders that accept GD-style inserts with clamp, screw, or self-grip holding methods. Confirm toolholder seat size matches Insert Size Code 24 before installation.

Installation Notes

CNC machinists and turning center operators should index or replace grooving inserts with the machine powered down and the spindle locked. Use the appropriate insert seating tool or torx key as specified by the toolholder manufacturer when securing with a screw-type clamp. Inspect the insert pocket and shim for wear or debris before seating a new insert. Never exceed the toolholder's recommended depth-of-cut or feed rate for this insert style.
