Hertel C.E11.1905 Extra Length Drill Bit 3/4 in Hss

Product Description

The HERTEL C.E11.1905 is a 3/4 inch diameter extra length drill bit designed for drilling applications that require deeper reach than standard-length tooling allows. Built from high-speed steel (HSS) with an oxide finish, it delivers heat resistance and wear durability across a range of workpiece materials. The 118 degree point angle is a general-purpose geometry suited for most metals and common shop materials. With a 12 inch flute length and 18 inch overall length, this bit handles deep-hole drilling in fabrication, HVAC, plumbing, and electrical rough-in work where standard bits cannot reach.

This extra length drill bit is used in applications where access depth is a limiting factor - drilling through deep structural members, framing assemblies, thick steel fabrications, or any situation requiring clearance beyond a jobber-length bit. It is well suited for trade professionals performing rough-in work, including plumbers, HVAC installers, and electricians drilling through multiple layers of material. The 2-flute configuration provides efficient chip evacuation during deep drilling passes.

Key Features

• 3/4 inch diameter with 18 inch overall length for extended reach
• 12 inch flute length supports deep drilling with continuous chip clearance
• 118 degree general-purpose point angle works across metals and common materials
• High-speed steel construction resists heat buildup during extended cuts
• Oxide finish reduces friction and provides mild corrosion resistance
• 2-flute design promotes chip evacuation in deep-hole applications

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 3/4 inch drill chucks and heavy-duty drill presses, magnetic drills, or right-angle drill drives used in trade applications.

Installation Notes

Install and remove this bit with the drill powered off and the chuck fully secured before operation. Extra length bits are more susceptible to deflection than jobber-length bits - use a center punch to establish a pilot point and apply steady, consistent feed pressure to reduce walking. Secure the workpiece before drilling. Operators should follow applicable shop safety standards and use appropriate cutting fluid when drilling through steel to extend bit life.
