Precision Twist Drill 5998736 35/64 Inch Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5998736 is a jobber-length twist drill bit designed for general-purpose hole-making in metal and hard materials. Built from high speed steel with a steam oxide coating, it measures 35/64 inches (0.5469 inches) in diameter with a 118-degree standard point angle. The overall length is 6.625 inches, and the flute length runs 4.8125 inches, providing a maximum drilling depth of 4.8125 inches. The web-thinned, tapered-web design reduces cutting resistance at the point. Licensed HVAC technicians, pipefitters, millwrights, and maintenance tradespeople reach for this bit when drilling structural steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium.

This bit suits jobsite and shop drilling operations where a straight-cylindrical shank is required for standard three-jaw chucks. The regular spiral with two flutes handles chip evacuation effectively in the listed workpiece materials. The Series R10 designation places it in a proven general-purpose family used across industrial maintenance, fabrication, and mechanical installation work. Sold individually, it fits into any standard drill press, magnetic drill, or hand-held electric drill accepting a 35/64-inch shank.

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any drill press, magnetic drill, or hand-held electric drill accepting a straight-cylindrical shank of 0.5469 inches in diameter. Rated for use in steel, stainless steel, cast iron, non-ferrous metal, superalloys, and titanium workpieces.

Installation Notes

Install in a properly sized three-jaw chuck and confirm the shank is fully seated before operating. Power down and de-energize or lock out the drill before changing bits. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to manage heat buildup and extend bit life. Follow shop safety procedures and applicable ANSI machine-tool guidelines when setting spindle speed for the workpiece material and bit diameter.
