Accupro ACC-G055-8 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G055-8 is a solid carbide internal grooving tool designed to cut retaining ring grooves in bored holes. Built from submicron-grade carbide, it delivers the edge retention and rigidity needed for precision groove work in ferrous and non-ferrous materials. The tool accepts a 3/8 inch shank and measures 2.5 inches in overall length. A 0.056 inch groove width and 0.110 inch projection make it well suited for tight-tolerance snap ring seat applications. Machinists and tool-and-die trades rely on this style of grooving tool for consistent, repeatable groove geometry on the lathe or in CNC turning operations.

This tool is used in internal grooving operations where a retaining ring groove must be cut into a bored hole. The minimum hole diameter it can enter is 0.375 inches, and it can reach a maximum hole depth of 0.5 inches. It is appropriate for production or job-shop turning environments where snap ring or circlip seats are required. The 2.0 inch shank length provides clearance for most standard tooling setups. A single tool per package is standard for this SKU.

Key Features

• 0.056 inch groove width sized for standard retaining ring seat dimensions
• 0.375 inch minimum hole diameter allows entry into small-bore workpieces
• 0.110 inch projection provides reach for groove depth without interference
• 2.0 inch shank length and 2.5 inch overall length suit standard lathe toolholders
• 3/8 inch shank diameter compatible with common boring bar and toolholder collets

Compatibility

Designed as an OEM-style grooving tool for use in standard 3/8 inch shank toolholders and boring bar systems configured for internal retaining ring groove operations.

Installation Notes

Installation is performed by qualified machinists on a lathe or CNC turning center. Secure the 3/8 inch shank firmly in a compatible toolholder before operation and verify tool runout is within acceptable limits. Power down and lock out the machine spindle before changing or adjusting the tool. Do not exceed the maximum hole depth rating of 0.5 inches to avoid deflection or tool breakage.
