Hertel 83240408 5/8 Inch Hss Jobber Length Drill Bit

Product Description

The HERTEL 83240408 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with an oxide coating for added wear resistance and heat dissipation, this bit delivers consistent performance across a range of common shop and field drilling tasks. It features a 118-degree standard point angle, a right-hand spiral flute pattern, and a straight-cylindrical shank sized at 0.6250 inches for secure chuck engagement. The overall length is 7-1/8 inches with a flute length of 5-3/16 inches, making it well-suited for through-hole and deep-feed applications where reach matters.

This bit is commonly used by HVAC technicians, plumbers, electricians, and general tradespeople for drilling pilot holes, clearance holes, and anchor holes in structural and sheet materials. The 5/8-inch diameter and jobber-length format make it a standard selection for conduit work, pipe hanger installations, equipment mounting, and bracket fabrication. Its general-purpose grade suits everyday production and maintenance drilling environments where consistent accuracy and tool longevity are required without the cost of specialty coatings.

Installation Notes

This drill bit is installed and operated by any trade professional using standard drilling equipment. Always secure the workpiece before drilling and confirm the chuck is fully tightened before operation. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if the point is chipped, worn, or burned.
