Precision Twist Drill 5997536 Jobber Drill 19/64 Inch Hss

Product Description

The PRECISION TWIST DRILL 5997536 is a 19/64 inch (0.2969 inches) diameter jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a steam oxide coating, it features a 118-degree standard point angle and a right-hand spiral flute configuration. The web-thinned, tapered web construction reduces thrust and improves chip evacuation. With an overall length of 4.375 inches and a flute length of 3.0625 inches, this bit suits production and maintenance drilling tasks performed by machinists, HVAC fabricators, plumbers, and electricians working with metal stock.

This jobber drill is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The straight-cylindrical shank fits standard three-jaw drill chucks across bench drills, drill presses, and hand-held power drills. It is appropriate for both shop fabrication and field service work where a reliable general-purpose drill bit is needed for metal drilling at moderate depths up to 3.0625 inches.

Installation Notes

Secure the shank fully in a properly sized drill chuck before operation and verify chuck key is removed before starting the drill. Power down all equipment and secure workpieces in a vise or clamp before bit changes. Use appropriate cutting fluid or lubricant when drilling steel or stainless steel to extend bit life and maintain cut quality. Drilling at excessive speed or feed without lubrication will shorten tool life and can damage the workpiece.
