Accupro ACC-G025K-4 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G025K-4 is a solid carbide retaining ring grooving tool designed for cutting internal grooves in bored holes. Built from submicron-grade carbide, it delivers the hardness and edge retention needed for precise, repeatable groove profiles in ferrous and non-ferrous materials. The tool has a 3/16 inch shank diameter and an overall length of 2 inches, making it compatible with standard boring setups on CNC lathes and machining centers. Machinists and tooling technicians use this tool when internal retaining ring grooves must be held to tight dimensional tolerances.

This grooving tool is suited for small-bore internal grooving applications where retaining ring grooves are required. It accommodates a minimum hole diameter of 0.187 inches and reaches a maximum hole depth of 0.25 inches (1/4 inch). The 0.05 inch projection and 0.0255 inch groove width make it appropriate for precision machined components in production or job-shop environments. It is a single-piece solid carbide tool, so no insert changes are required during its service life.

Key Features

• Solid submicron carbide construction for superior wear resistance and edge stability
• Groove width of 0.0255 inches for precise retaining ring seat profiles
• Minimum hole diameter of 0.187 inches enables use in small-bore applications
• Maximum hole depth of 0.25 inches with 0.05 inch projection
• 3/16 inch shank diameter fits standard toolholders without modification
• Overall length of 2 inches for compact, rigid setup in tight clearance conditions

Compatibility

Designed as an OEM-style replacement and standard tooling option for internal retaining ring grooving operations on CNC lathes, manual lathes, and machining centers accepting 3/16 inch shank boring tools.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the shank firmly in the toolholder to the manufacturer-recommended clamping method to prevent deflection during grooving passes. Verify bore diameter and depth clearances before engaging the tool to avoid tool breakage in undersized holes.
