Hertel C.E09.0318 Extra Length Drill Bit 1/8 Inch Hss

Product Description

The HERTEL C.E09.0318 is a 1/8-inch extra length twist drill bit engineered for applications where standard-length bits cannot reach. Manufactured from high-speed steel with an oxide finish, it delivers solid performance in general-purpose drilling across steel, cast iron, aluminum, wood, and plastics. The 118-degree split point geometry provides reliable centering and clean entry. With a 10-inch overall length and a 7.5-inch flute length, this bit gives machinists, pipefitters, fabricators, and maintenance technicians the reach needed for deep-hole or extended-clearance work. The two-flute design promotes efficient chip evacuation throughout the cut.

This bit is suited for general-purpose drilling in both shop and field settings. Common applications include structural fabrication, HVAC duct and bracket work, plumbing rough-in, electrical panel and conduit work, and maintenance repair operations where standard 6-inch jobber bits fall short. The 1/8-inch diameter makes it appropriate for pilot holes, through-hole passes in thin-gauge sheet metal, and locating operations prior to step drilling or tapping.

Key Features

• Extra length design at 10 inches overall for extended-reach drilling
• 1/8-inch diameter with 118-degree drill point angle for accurate centering
• High-speed steel construction rated for general-purpose use across common metals and wood
• Oxide finish helps reduce friction and provides light corrosion resistance
• 7.5-inch flute length promotes chip clearance in deep-hole applications
• Two-flute geometry for balanced cutting action

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 3-jaw drill chucks and collet systems accepting 1/8-inch shank tooling.

Installation Notes

This bit is installed and used by machinists, fabricators, and trade mechanics working with handheld or stationary drilling equipment. Secure the shank fully in the chuck before use and verify concentricity to avoid premature wear or breakage. Reduce feed rate and apply cutting fluid when drilling ferrous metals to extend bit life. High-speed steel bits are not rated for hardened steel or masonry and should not be used with hammer-drill mode.
