Harvey Tool 25670 Combo Drill Countersink Size 5 Solid Carbide

Product Description

The HARVEY TOOL 25670 is a solid carbide combined drill and countersink designed for precision center drilling and countersinking in a single operation. With a trade size of 5 and a body diameter of 7/16 inches, this tool features a 3/16-inch drill point diameter and a 118-degree drill point angle. The included angle measures 82 degrees, making it suited for creating accurate center holes with a properly angled countersink seat. The bright, uncoated carbide construction provides rigidity and heat resistance during demanding machining operations. Machinists and CNC operators working with metalworking lathes, mills, and drill presses are the primary users of this tool.

This combined drill and countersink is used in metal fabrication shops, machine shops, and production environments where accurate center drilling is required before turning or grinding operations. The double-end style maximizes tool life by offering two usable ends. Right-hand cutting direction makes it compatible with standard spindle rotation on most machining equipment. The 2-3/4-inch overall length fits standard toolholders used in both manual and CNC machine applications.

Installation Notes

This tool is installed and used by machinists in machine shop environments. Secure the tool in a properly sized collet or toolholder and ensure the spindle is fully stopped before making any tool changes. Follow applicable shop safety procedures and machine manufacturer guidelines when setting speeds and feeds for carbide tooling. Inspect both cutting ends for chipping or wear before use.
