Harvey Tool 23408-C3 Solid Carbide Counterbore 0.125 in

Product Description

The HARVEY TOOL 23408-C3 is a solid carbide counterbore designed for precision spot-facing and counterboring operations in tight-tolerance machining applications. With a 0.125 inch cutting diameter and a 0.5 inch flute length, this tool is built for small-diameter work where rigidity and accuracy are critical. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hardened materials. Four flutes deliver smooth chip evacuation and a consistent finish. This counterbore is used by machinists and toolmakers working on CNC machining centers and manual mills.

This tool is suited for creating flat-bottomed recesses to seat fastener heads or precision components in close-tolerance workpieces. Its 0.125 inch shank diameter and 1.5 inch overall length make it compatible with standard collet and end mill holder setups. The AlTiN finish makes it a strong choice for dry or minimal-lubrication cutting in stainless steel, alloy steel, and hardened materials. It is commonly used in aerospace, medical device, and precision industrial manufacturing environments.

Key Features

• 0.125 inch cutting diameter for small-diameter counterboring applications
• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 4-flute geometry for smooth chip evacuation and improved surface finish
• Solid carbide construction provides rigidity and dimensional stability
• 0.5 inch flute length accommodates typical fastener-head recess depths at this diameter
• 1.5 inch overall length suits standard short-reach toolholding setups

Compatibility

Designed as an OEM-style solid carbide counterbore for use in standard 0.125 inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and use of this tooling should be performed by qualified machinists familiar with proper toolholding and spindle speed selection for carbide end geometry. Ensure the collet or holder is clean and properly torqued before engaging the workpiece. Solid carbide tooling is brittle and susceptible to chipping if subjected to side loads or improper runout — verify holder runout before cutting. Follow machine manufacturer guidelines and applicable shop safety procedures when operating rotating cutting tools.
