Hertel C.E11.1548 Extra Length Drill Bit 0.6094 in Hss

Product Description

The HERTEL C.E11.1548 is an extra length twist drill bit designed for deep-hole drilling applications where standard-length bits fall short. Built from high-speed steel (HSS) with an oxide finish, it measures 0.6094 inches in diameter with a 12-inch flute length and an 18-inch overall length. The 118-degree point angle suits general-purpose drilling in a range of materials. The two-flute design promotes efficient chip evacuation during extended-depth cuts. This bit is a practical tool for HVAC fabricators, plumbers, electricians, and general trade contractors who need to bore through deep structural members, equipment pads, or thick assemblies.

This extra length drill bit is suited for applications requiring reach beyond what jobber-length bits provide, such as drilling through deep wall cavities, thick structural steel, wood framing stacks, or equipment housings. The oxide surface finish provides moderate lubricity and helps resist heat buildup during drilling. General-purpose grade construction makes it appropriate for use in steel, cast iron, aluminum, wood, and similar materials encountered in trade installation and fabrication work. Sold individually.

Key Features

• Extra length design at 18 inches overall length provides reach for deep-hole applications
• 12-inch flute length supports chip clearance throughout deep cuts
• 0.6094-inch diameter for precise bore sizing
• 118-degree point angle for general-purpose material compatibility
• High-speed steel construction maintains hardness under drilling heat
• Oxide finish provides lubricity and moderate corrosion resistance

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and drilling equipment accepting 0.6094-inch round shanks.

Installation Notes

This bit is installed and used by trade professionals including electricians, HVAC technicians, plumbers, and general contractors. Secure the bit firmly in a compatible drill chuck before operation and confirm the chuck is tightened to prevent slipping. Use appropriate cutting fluid or lubricant when drilling through ferrous metals to extend bit life and manage heat. When drilling deep holes, withdraw the bit periodically to clear chips and prevent binding.
