Hertel H-81154L06060 Combo Drill Countersink Hss Size 6

Product Description

The HERTEL H-81154L06060 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool delivers clean, precise results in metal fabrication, sheet metal work, and general machining applications. It features a 118-degree drill point angle, a 7/32-inch point diameter, and an 82-degree included angle for the countersink, making it well-suited for preparing fastener seats in steel, aluminum, and similar materials. The 6-inch overall length qualifies it as a long-length tool, providing additional reach for deeper setups or awkward clearance situations.

This combo drill countersink is intended for use in machine shops, maintenance facilities, and fabrication environments where countersinking for flat-head or flush-mount fasteners is a routine operation. The size 6 trade designation and 1/2-inch body diameter are standard for benchtop drill presses, milling machines, and CNC machining centers. The double end-type design and plain cutting edge style suit a wide range of ferrous and non-ferrous materials. It is typically installed and operated by machinists, tool and die makers, and skilled maintenance technicians.

Key Features

• Combination drill and countersink completes two operations in one pass
• High-speed steel construction for durability in general-purpose machining
• Bright uncoated finish suitable for dry cutting and standard lubricated applications
• 82-degree included countersink angle for standard flat-head fastener seating
• 118-degree drill point angle for positive starts on flat and curved surfaces
• Long-length design at 6 inches OAL provides extended reach in deep setups

Compatibility

Designed as an OEM-style replacement or direct substitute for size 6 combo drill countersinks with a 1/2-inch body diameter used in standard drill press and milling machine spindles accepting straight-shank tooling.

Installation Notes

This tool is installed and operated by machinists and maintenance technicians in machine tool spindles or drill press chucks. Always secure the straight shank firmly in an appropriate collet or drill chuck before operation, and verify that spindle speed is appropriate for the material and tool diameter. Ensure the workpiece is clamped securely to prevent movement during the combined drilling and countersinking operation. Follow applicable shop safety standards and consult material-specific cutting fluid recommendations as needed.
