The MICRO 100 RR-087-20 is a solid carbide internal grooving tool engineered for cutting retaining ring grooves in bored holes. Built from solid carbide, it delivers the rigidity and wear resistance required for precise groove geometry in production and maintenance machining environments. The tool features a 3/8 inch shank diameter, a 0.087 inch groove width, and a 0.100 inch projection, making it suited for tight-tolerance retaining ring groove applications in small-diameter bores. Machinists and toolroom technicians working on lathes or boring machines are the primary users of this tool.
The RR-087-20 is used in applications where internal retaining ring grooves must be cut into bored holes with a minimum diameter of 0.375 inches. Maximum hole depth reaches 1.25 inches, and overall tool length is 2.5 inches. It is appropriate for production machining, repair, and toolroom work across industrial, automotive, and mechanical assembly contexts where snap ring grooves are required to retain components on shafts or within bores.
Designed for use in lathes and boring machines accepting a 3/8 inch shank toolholder or collet. Suitable for cutting internal retaining ring grooves in bores with a minimum diameter of 0.375 inches and a maximum depth of 1.25 inches.
Installation is performed by qualified machinists on lathes or CNC turning centers. Ensure the machine spindle is fully stopped and the tool is securely clamped in a matched collet or toolholder before beginning any operation. Verify shank runout and projection length against workpiece bore geometry before engaging the cut. Follow applicable shop safety procedures and machine manufacturer guidelines when setting tool offsets.
