Hertel 300-006002 Combo Drill Countersink Solid Carbide

Product Description

The HERTEL 300-006002 is a solid carbide combination drill and countersink designed to drill a pilot hole and countersink in a single pass. It carries a Trade Size of No. 2 with a body diameter of 3/16 inches and a bright polished finish. The drill point measures 5/64 inches in diameter and 5/64 inches in length, with an overall length of 4 inches. The included countersink angle is 82 degrees and the drill point angle is 118 degrees. Right-hand cut geometry and a plain cutting edge make this tool suitable for use in a drill press, CNC machine, or hand drill. Machinists, tool-and-die workers, and metalworking professionals use this type of tool for consistent, repeatable countersink profiles.

This combo drill countersink is intended for applications where a flat-head fastener seat must be prepared in metal, composite, or similar materials. The double-end style extends tool life by providing two usable ends. The long-length configuration accommodates deeper reach requirements in production and maintenance machining environments. It is not configured for aircraft-style or tapered countersink profiles, making it suited to standard 82-degree flat-head fastener applications in general metalworking and fabrication.

Key Features

• Solid carbide construction for wear resistance and rigidity in demanding materials
• Bright polished finish reduces chip adhesion and friction during cutting
• Single-pass design drills pilot hole and countersinks simultaneously
• Double-end configuration provides two cutting ends for extended service life
• 82-degree included angle matches standard flat-head fastener geometry
• Long-length body at 4 inches overall accommodates extended reach applications

Compatibility

Designed as a standard No. 2 combination drill countersink for use in drill presses, CNC machining centers, and hand drilling equipment that accept 3/16-inch shank tooling.

Installation Notes

This tool is installed and operated by machinists and metalworking professionals. Secure the shank firmly in a compatible chuck or collet before use and verify that spindle speed is appropriate for the material and tool diameter. Inspect both cutting ends before use and replace the tool if chipping or wear is detected on the active end. Do not exceed the tool's rated capacity or use it on materials outside its intended application.
