Hertel H-81155L01060 Combo Drill Countersink Hss 6 in

Product Description

The HERTEL H-81155L01060 is a combination drill and countersink tool designed to drill a pilot hole and cut a countersink in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool features a 1/8 inch body diameter, a 3/64 inch drill point diameter, and a 90-degree included angle for the countersink portion. The 118-degree drill point angle is standard for general-purpose metal drilling. At 6 inches overall length, this is a long-length tool suited for applications requiring extended reach. It is installed and used by machinists, tool and die workers, and maintenance technicians working with metal fabrication or assembly.

This combo drill countersink is used in metalworking and light fabrication environments where countersunk fastener seats must be prepared precisely. The double-end style and plain cutting edge make it compatible with standard drill press, CNC, or hand-held power drill setups. Its long-length design allows access to recessed or deeper workpieces. Typical applications include countersinking for flat-head screws in steel, aluminum, and similar materials. Sold individually, this is a trade size 1 tool appropriate for bench and production use where consistent countersink geometry is required.

Installation Notes

This tool is installed by machinists or maintenance technicians in a standard drill chuck. Ensure the workpiece is properly clamped before operation and the spindle speed is set appropriately for the material being drilled. Inspect the cutting edges before use and replace the tool if chipping or wear is visible. Follow standard machine shop safety practices, including the use of appropriate eye protection and cutting fluid where applicable.
