Precision Twist Drill 5999368 Jobber Drill Bit No 29

Product Description

The PRECISION TWIST DRILL 5999368 is a jobber-length drill bit sized at No. 29 wire gauge (0.1360 inches decimal), manufactured from high speed steel with a steam oxide coating. It features a 118-degree standard point angle and a right-hand spiral flute configuration for general-purpose drilling applications. The two-flute, web-thinned design reduces thrust and promotes clean chip evacuation. With an overall length of 2.875 inches and a flute length of 1.75 inches, this bit is suited for shop and field use by machinists, pipefitters, HVAC technicians, and other trades requiring precision hole-making in tight tolerances.

This drill bit is designed for drilling into a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is well suited for residential and commercial applications where a standard jobber-length bit is required. The straight-cylindrical shank accepts standard three-jaw drill chucks across a wide range of drill presses, hand drills, and right-angle drivers commonly found in trade environments. It conforms to ANSI standards and meets NAS 907 specification requirements.
