Precision Twist Drill 5999712 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999712 is a taper length, straight-shank drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a bright, uncoated finish, it measures 0.1695 inches in diameter and carries a wire size designation of 18. The 118-degree standard point angle suits common workshop and field applications across metals and non-metals alike. A tapered web configuration and web-thinned point reduce thrust during entry and help maintain accuracy in production and maintenance drilling tasks. Licensed tradespeople and machinists reach for this bit when a longer flute length is needed beyond what a jobber-length drill provides.

This drill bit fits general-purpose applications across maintenance, repair, and light manufacturing environments. Its 5.75-inch overall length and 3.375-inch flute length make it well suited for drilling deeper holes where a standard jobber bit falls short. Right-hand, spiral-flute cutting geometry is compatible with standard drill presses, hand drills, and CNC drill setups. The Series R52 designation places it within a recognized Precision Twist Drill product family used in industrial and trade shop settings.

Installation Notes

Install this bit into a standard drill chuck sized for a 0.1695-inch straight shank, ensuring the shank is fully seated and the chuck is tightened securely before operation. Power down or de-energize any drill press or machine before changing bits. Use appropriate cutting fluid or lubricant when drilling ferrous metals or stainless steel to extend bit life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece before drilling.
