Precision Twist Drill 5999201 Jobber Drill Bit 10 Hss

Product Description

The PRECISION TWIST DRILL 5999201 is a jobber-length drill bit in wire size number 10, measuring 0.1935 inches in decimal diameter. Made from high speed steel with a bright uncoated finish, it features a standard 118-degree point angle and a two-flute regular spiral design with a tapered web configuration. The web-thinned tip reduces thrust and improves chip evacuation. Overall length is 3.625 inches with a flute length of 2.4375 inches. This bit is suited for general-purpose drilling in metalworking environments and is commonly used by machinists, maintenance technicians, and fabricators working with precision hole tolerances in wire gauge sizes.

This drill bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks via its straight cylindrical shank at 0.1935 inches in diameter. The right-hand spiral flute and standard point make it appropriate for production drilling, maintenance repair, and general fabrication applications where consistent hole quality in a wire gauge size is required. It conforms to ANSI standards and belongs to Precision Twist Drill series R10P, R15P, and R18P.
