Precision Twist Drill 5999243 Wire Size 53 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999243 is a wire gauge size 53 jobber length drill bit built for general-purpose drilling in metal and hard materials. It measures 0.0595 inches in diameter with an overall length of 1.875 inches and a flute length of 0.875 inches. The bit is manufactured from high speed steel with a steam oxide coating that reduces friction and extends tool life in production drilling environments. The 118-degree standard point angle and right-hand spiral flute geometry suit it for use in drill presses, hand drills, and CNC setups. A tapered web with web thinning reduces thrust at entry and improves chip evacuation. This bit is sold individually and is sized for precision hole work where wire gauge tolerances are required.

Wire gauge drill bits in the 53 range are commonly used in metalworking shops, aerospace maintenance environments, and machine shops for tapping prep holes, clearance holes, and close-tolerance work. The Series R18 designation places this bit in PRECISION TWIST DRILL's standard jobber line. It is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight cylindrical shank with no flats seats cleanly in standard drill chucks without slippage under normal feed rates.

Installation Notes

This bit is installed and removed by a licensed machinist or qualified metalworking technician using a standard keyed or keyless drill chuck. Ensure the machine is fully powered down and the spindle is locked before changing bits. Use appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to prevent work hardening and premature edge wear. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and speed selection by material.
