Hertel C.E12.1905 Extra Length Drill Bit 3/4 in Hss

Product Description

The HERTEL C.E12.1905 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. The bit measures 3/4 inch in diameter with a 24-inch overall length and an 18-inch flute length, providing extended reach without sacrificing chip evacuation. The 118-degree point angle is a general-purpose geometry suitable for a wide range of ferrous and non-ferrous materials. The oxide finish helps reduce friction and provides a degree of corrosion resistance during use. This bit is suited for machinists, fabricators, pipefitters, and mechanical contractors who need to drill through structural members, thick plates, or stacked materials.

This drill bit is used in applications requiring deep penetration, such as drilling through structural steel, heavy fabrications, pipe flanges, or thick wood and composite members. Its extended flute length of 18 inches allows chips to clear efficiently during deep-hole operations. General-purpose grade construction makes it appropriate for use in drill presses, magnetic base drills, and CNC setups where a 3/4-inch chuck or collet is available. It is a single-unit sale with no minimum order beyond one piece.

Key Features

• 3/4 inch diameter with 24-inch overall length for extended reach drilling
• 18-inch flute length promotes chip evacuation in deep-hole applications
• 118-degree point angle suits general-purpose drilling in metal and other materials
• High-speed steel construction provides toughness and heat resistance
• Oxide finish reduces surface friction during drilling operations
• Two-flute design balances chip clearance and cutting efficiency

Compatibility

Designed as a general-purpose extra length drill bit compatible with any drill press, magnetic base drill, or CNC machine accepting a 3/4-inch shank diameter tool.

Installation Notes

Extra length drill bits should be secured firmly in a drill chuck or collet rated for the shank diameter before use. Secure the workpiece to prevent movement during drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and maintain accuracy. Extended-length bits are more susceptible to deflection — reduce feed pressure and use a pilot hole when precision location is required.
