Cleveland C73426 15/32 in Hss Jobber Length Drill Bit

Product Description

The CLEVELAND C73426 is a jobber-length drill bit designed for precision hole-making in metal fabrication, maintenance, and light industrial applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree split point that reduces walking on entry and improves centering accuracy. At 15/32 inch (0.4688 inch decimal) diameter, it falls in the heavy-duty grade category and meets NAS 907 Type A standards. The two-flute spiral design and web-thinned, tapered web configuration promote efficient chip evacuation during drilling. Licensed HVAC technicians, plumbers, electricians, and general tradespeople rely on this size for conduit, bracket, and sheet metal work.

This drill bit is suited for right-hand drilling operations in aluminum and similar workpiece materials across residential and commercial job sites. With an overall length of 5.75 inches and a flute length of 4.3125 inches, it fits standard drill chucks and magnetic drill presses without modification. The straight-cylindrical shank at 0.4688 inch diameter seats securely in three-jaw chucks, and the regular spiral type maintains consistent feed rates across varying material thicknesses.

Installation Notes

This drill bit is installed by electricians, HVAC technicians, plumbers, and general tradespeople using handheld or bench-mounted electric drills. Always secure the workpiece before drilling and use appropriate cutting fluid when working with harder materials to extend bit life. Ensure the drill is powered off and the bit is fully seated and tightened in the chuck before operation. Follow applicable safety codes and personal protective equipment requirements for your trade and jurisdiction.
