Hertel C.E08.1270 Extra Length Drill Bit 1/2 Inch Hss

Product Description

The HERTEL C.E08.1270 is a 1/2 inch extra length twist drill bit manufactured from high-speed steel with an oxide finish. It is designed for drilling through metal, wood, plastics, and other common shop materials where standard-length bits cannot reach. With an overall length of 8 inches and a 5.5 inch flute length, this bit provides extended reach into deep holes or recessed work areas. The 118-degree point angle is a general-purpose geometry suited to a wide range of materials. Two flutes clear chips efficiently during drilling. Machinists, pipefitters, ironworkers, and general fabricators will find this bit useful for structural and maintenance drilling applications.

This extra length drill bit is intended for general-purpose use in machine shops, fabrication facilities, and maintenance environments. The extended overall length of 8 inches makes it appropriate when standard-length bits lack the reach required for deep holes, long-reach drilling through structural members, or drilling through assemblies. It fits standard 1/2 inch drill chucks on bench drills, drill presses, and portable electric drills. The oxide finish provides a basic level of surface protection and reduces friction slightly during cutting operations.

Key Features

• 1/2 inch (0.5000 inch) diameter for use with standard 1/2 inch chucks
• 8 inch overall length provides extended reach beyond standard jobber-length bits
• 5.5 inch flute length for deep chip evacuation
• 118-degree drill point angle suits general-purpose drilling across multiple materials
• High-speed steel construction handles moderate heat and maintains edge life in production use
• Oxide finish reduces surface friction and provides basic corrosion resistance
• Two-flute design for efficient chip clearing

Compatibility

Designed as a general-purpose extra length drill bit compatible with any standard 1/2 inch drill chuck on bench drills, drill presses, and portable electric drills used in machining and fabrication applications.

Installation Notes

This bit is installed and removed by a licensed machinist or qualified tradesperson using a standard drill chuck key or keyless chuck system. Secure the bit fully in the chuck before operation and verify the workpiece is firmly clamped before drilling. Wear appropriate eye protection and follow all applicable shop safety procedures. Use cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup.
