Accupro ACC-G156-12 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G156-12 is a solid carbide retaining ring grooving tool designed for cutting internal grooves that seat retaining rings in bored holes. Built from submicron-grade solid carbide, this tool delivers the hardness and edge retention needed for precision grooving in metal components. It features a 0.5-inch shank diameter and an overall length of 3 inches, with a groove width of 0.157 inches and a projection of 0.16 inches. Machinists and tool-and-die professionals use this tool on CNC lathes and manual boring setups where consistent groove geometry is critical to proper retaining ring function.

This grooving tool is suited for internal retaining ring groove applications in production machining and maintenance environments. With a minimum hole diameter of 0.5 inches and a maximum hole depth of 0.75 inches, it fits compact bore applications where clearance is limited. The submicron carbide grade makes it a reliable choice for ferrous and non-ferrous metals where surface finish and dimensional accuracy at the groove determine whether a retaining ring seats and holds correctly under load.

Key Features

• Solid carbide construction in submicron material grade for extended tool life and edge stability
• 0.157-inch groove width sized for standard retaining ring profiles
• 0.5-inch shank diameter fits standard ER and collet toolholders
• 0.16-inch projection provides controlled cutting depth for consistent groove geometry
• Maximum hole depth of 0.75 inches accommodates typical shallow-bore retaining ring applications
• 3-inch overall length balances reach and rigidity in bore setups

Compatibility

Designed as a direct-fit grooving tool for internal retaining ring groove operations on CNC and manual lathes equipped with 0.5-inch collet or toolholder systems accepting standard round-shank boring tools.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist familiar with internal grooving operations. Secure the 0.5-inch shank firmly in the toolholder and verify runout before engaging the workpiece. Confirm spindle speed and feed rate are appropriate for the workpiece material and carbide tooling before making the cut. Inspect the tool edge for chipping before each use, as carbide grooving tools are sensitive to interrupted cuts and improper fixturing.
