Hertel C.E11.1067 Extra Length Drill Bit 0.42 in Hss

Product Description

The HERTEL C.E11.1067 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where standard-length bits fall short. It measures 18 inches in overall length with a 12-inch flute length, making it well suited for reaching into deep bores, fabricated assemblies, or structural members that require extended reach. The 118-degree split-point geometry provides good centering and cutting action across a range of materials. The oxide finish offers mild corrosion resistance and reduces friction during operation. This bit is used primarily by machinists, pipefitters, ironworkers, and general tradespeople who need reliable metal drilling performance in demanding jobsite or shop conditions.

This drill bit is a general-purpose tool appropriate for drilling ferrous and non-ferrous metals, including mild steel, cast iron, aluminum, and similar materials. Its extended overall length of 18 inches suits applications such as drilling through wall framing, structural steel, conduit pathways, or mechanical assemblies where standard jobber-length bits cannot reach. It is commonly used in mechanical contracting, industrial maintenance, and fabrication shop environments. The two-flute design provides efficient chip evacuation during deep drilling passes.

Key Features

• 18-inch overall length for deep-reach drilling applications
• 12-inch flute length supports chip evacuation in extended bores
• 118-degree drill point angle for general-purpose metal drilling
• High-speed steel construction provides hardness and heat resistance
• Oxide finish reduces friction and provides mild surface protection
• Two-flute design for efficient chip clearance

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and magnetic drill presses accepting 0.42-inch diameter round-shank bits.

Installation Notes

This bit is installed and operated by machinists, pipefitters, electricians, and general tradespeople using hand drills, drill presses, or magnetic base drills. Secure the workpiece before drilling and use appropriate cutting fluid when drilling ferrous metals to extend tool life and manage heat. Reduce feed pressure as the bit exits the material to prevent grabbing or breakage. Inspect the cutting edges before use and replace the bit if chipping or dulling is observed.
