Hertel C.E08.0318 Extra Length Drill Bit 1/8 in Hss

Product Description

The HERTEL C.E08.0318 is an extra length high-speed steel drill bit designed for drilling applications that require greater reach than a standard-length bit provides. Ground to a 118-degree point angle, it suits general-purpose drilling in a wide range of materials. The oxide finish provides a degree of lubricity and corrosion resistance during use. At 8 inches overall length with a 5.5-inch flute length, this bit gives tradespeople access to deep-hole applications where stub or jobber-length bits fall short. It is a two-flute design, consistent with standard twist drill geometry for chip evacuation and straightforward regrinding.

This bit is suited for metal fabrication shops, mechanical contractors, HVAC installers, and maintenance technicians who need to drill through structural steel, tubing, sheet metal, or similar materials in confined or deep-reach situations. The 1/8-inch diameter makes it appropriate for pilot holes, conduit knockouts, sheet metal work, and other small-diameter drilling tasks where a longer reach is required. It is sold individually and fits standard drill chucks that accept round shanks at this diameter.

Key Features

• 1/8 inch (0.1250 inch) diameter for small-bore and pilot-hole applications
• 8 inch overall length provides extended reach beyond standard jobber bits
• 5.5-inch flute length supports deep-hole chip evacuation
• 118-degree split or conventional point angle for general-purpose use on steel and similar materials
• High-speed steel construction withstands heat generated during drilling
• Oxide finish reduces friction and offers light corrosion resistance during storage and use

Compatibility

Designed as a general-purpose extra length twist drill bit compatible with any standard drill chuck or drill press accepting a 1/8-inch round shank.

Installation Notes

This bit is installed by a machinist, fabricator, or mechanical trade technician using a handheld drill driver or drill press. Secure the shank firmly in the chuck before operation and verify the work piece is clamped or fixtured to prevent movement. Use cutting fluid or a suitable lubricant when drilling steel to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace or regrind the bit if the point shows signs of wear or chipping.
