Hertel C.E11.1826 Extra Length Drill Bit 0.7188 in Hss

Product Description

The HERTEL C.E11.1826 is an extra length high-speed steel drill bit designed for deep-hole drilling applications that standard-length bits cannot reach. It measures 0.7188 inches in diameter and features a 118-degree split-style point angle suited for general-purpose work in a wide range of materials. The 18-inch overall length and 12-inch flute length give machinists and fabricators extended reach through thick stock, stacked materials, or structural members. An oxide finish provides basic lubricity and corrosion resistance. With two flutes for efficient chip evacuation, this bit is built for controlled, straight penetration in production and maintenance drilling environments.

This drill bit is used in metalworking, fabrication shops, structural steel work, mechanical contracting, and maintenance settings where standard 6-inch or 12-inch bits fall short. The extended geometry suits applications such as drilling through deep weldments, structural beams, HVAC equipment frames, and thick plate. It is appropriate for use in a drill press, magnetic base drill, or heavy-duty hand drill with adequate torque capacity. General-purpose grade construction makes it a practical choice for carbon steel, mild alloys, and similar materials encountered in trade and industrial work.

Key Features

• 0.7188 inch diameter for precise, consistent bore sizing
• 18-inch overall length delivers extended reach in deep-hole applications
• 12-inch flute length supports effective chip evacuation throughout the cut
• 118-degree point angle is optimized for general-purpose drilling in metal and similar materials
• High-speed steel construction withstands heat and wear in production environments
• Oxide finish adds surface lubricity and basic corrosion resistance

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and magnetic base drills accepting a straight shank in the 0.7188-inch diameter range.

Installation Notes

This bit should be installed by a machinist or qualified tradesperson in a drill press, magnetic base drill, or heavy-duty drill rated for the shank diameter. Secure the workpiece firmly before drilling to prevent movement and ensure straight entry. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and do not force a dull or damaged bit.
