The HORN R105081019TI25 is a solid carbide grooving tool designed for internal grooving and undercutting operations in precision machining applications. With an overall length of 2.5 inches and a 5/16-inch shank diameter, this tool is built for use in CNC lathes and manual turning centers where tight tolerances and consistent groove geometry are required. The minimum hole diameter it accommodates is 0.322 inches, and it delivers a projection of 0.110 inches, making it suited for shallow-depth grooving work in small-bore applications. Machinists and tool-room technicians are the primary installers of this type of tooling.
This grooving tool is intended for use in metal-cutting environments where internal groove profiles must be held to close dimensional tolerances. It is well suited for small-diameter bores in ferrous and non-ferrous workpieces. The solid carbide construction supports use at higher cutting speeds compared to high-speed steel alternatives, and the compact overall length allows it to fit within confined toolholder setups. Typical applications include internal relief grooves, snap-ring grooves, and undercut features in turned components across light manufacturing and job-shop environments.
Designed as an OEM-style grooving tool for use with compatible toolholders accepting a 5/16-inch shank diameter in CNC and manual turning applications.
Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the machine is locked out before changing or seating tooling. Solid carbide tools are brittle and should not be subjected to interrupted cuts or side loads beyond their rated projection. Verify shank seating depth and clamping torque per the toolholder manufacturer specifications before resuming operation.
