Micro 100 UP-25030-8 Undercut Grooving Tool Solid Carbide

Product Description

The MICRO 100 UP-25030-8 is a solid carbide undercut grooving tool designed for precision internal grooving and undercutting operations on machined bores. It features a 0.030 inch groove width and a 0.500 inch shank diameter, making it suited for tight-tolerance work in small to medium bore diameters. The solid carbide construction provides rigidity and wear resistance needed for consistent, repeatable cuts. This tool is used primarily by machinists and toolmakers running CNC lathes or manual turning equipment in production and job-shop environments.

The UP-25030-8 is intended for internal undercut and grooving applications where the minimum bore diameter is 0.482 inches. With a projection of 0.150 inches and a maximum hole depth of 0.500 inches, it is well matched to shallow undercutting tasks in ferrous and non-ferrous materials. It fits standard tool holders accepting a 0.500 inch shank and is a common choice for snap-ring groove cutting, relief groove machining, and similar precision bore work.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding cutting conditions
• 0.030 inch groove width for precise, narrow undercut profiles
• 0.482 inch minimum hole diameter allows use in small bores
• 0.150 inch projection supports controlled depth in shallow undercut applications
• 3.000 inch overall length with 0.500 inch shank diameter for stable tool holder engagement
• Maximum hole depth of 0.500 inches limits overhang and reduces deflection risk

Compatibility

Designed for use in tool holders and boring bars accepting a 0.500 inch round shank. Suitable for CNC and manual lathes performing internal undercut and grooving operations in bores with a minimum diameter of 0.482 inches.

Installation Notes

Installation and tool changes should be performed with the machine in a full stop and lockout-tagout procedures followed per shop safety standards. Secure the shank firmly in the tool holder to the full recommended engagement depth to minimize deflection. Inspect the cutting edge for chips or wear before each use, as carbide tooling is brittle and edge damage affects cut quality. Consult the machine manufacturer and tooling documentation for appropriate speeds and feeds for the workpiece material.
