Precision Twist Drill 5995519 7/64 Inch Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5995519 is a jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous and non-ferrous materials. It measures 7/64 inch (0.1094 inches) in diameter with a 118-degree standard point angle and is manufactured from high-speed steel (HSS) with a bright, uncoated finish. The left-hand cutting direction makes it well-suited for reverse-drilling applications, such as extracting broken fasteners or drilling out studs. With an overall length of 2-5/8 inches and a 1-1/2-inch flute length, it fits standard drill chucks used by machinists, maintenance technicians, and trade professionals working with ferrous metals.

This bit is used in production and maintenance drilling applications where a left-hand cut is required. The Series L10 designation places it in a general-purpose jobber-length lineup. It is appropriate for use in steel and cast iron workpieces and follows ANSI standards for dimensional accuracy. Typical applications include metalworking, mechanical maintenance, and fastener extraction tasks across HVAC, plumbing, electrical, and general industrial trades. The straight shank accepts standard three-jaw drill chucks on both corded and cordless equipment.

Installation Notes

This bit is installed by machinists, maintenance mechanics, and trade technicians using corded or cordless drills and drill presses equipped with a compatible three-jaw chuck. Secure the straight shank firmly in the chuck before operation and confirm the drill is set to reverse rotation to engage the left-hand cut. Always wear appropriate eye protection when drilling metal, and use cutting fluid on ferrous materials to extend bit life and improve hole quality. Follow applicable shop safety standards and equipment manufacturer guidelines for speed and feed settings.
