The ACCUPRO ACC-G039-16 is a solid carbide internal grooving tool designed to cut retaining ring grooves in bored holes. Built from submicron carbide grade material, it delivers the hardness and edge retention needed for precision grooving in ferrous and non-ferrous metals. The tool accepts a 3/8-inch shank and produces a groove width of 0.0400 inches. With an overall length of 2.5 inches and a shank length of 1.2 inches, it fits standard boring bar setups and CNC turning centers. Machinists and tool-and-die professionals use this tool where snap ring or retaining ring grooves are required inside bored diameters.
This grooving tool is suited for internal retaining ring groove applications in machining operations on lathes and turning centers. It requires a minimum hole diameter of 0.3750 inches and supports a maximum hole depth of 1.0 inch, making it appropriate for shallow-to-medium depth bore grooving. The submicron carbide construction handles interrupted cuts and tight tolerance work typical in precision component manufacturing and repair shops.
Designed as an OEM-style precision grooving tool for use in lathes and CNC turning centers that accept a 3/8-inch shank toolholder, where internal retaining ring groove cutting is required.
Installation is performed by qualified machinists in a lathe or CNC turning center environment. Ensure the machine spindle is fully stopped and the tool is properly torqued in the toolholder before beginning any cut. Verify bore diameter meets the 0.3750-inch minimum before engaging the tool to avoid tool breakage. Follow shop safety protocols and machine manufacturer guidelines when setting tool offsets and depth of cut.
