Precision Twist Drill 5998834 Drill Bit Letter P Hss

Product Description

The PRECISION TWIST DRILL 5998834 is a jobber-length drill bit sized to letter P (0.3230 inches) and manufactured from high-speed steel with a steam oxide coating. It features a 118-degree standard point angle, a right-hand spiral flute configuration, and a straight-cylindrical shank. Overall length measures 4.625 inches with a flute length of 3.3125 inches. The web-thinned, tapered-web design reduces thrust load on entry and improves chip evacuation. This bit is suited for general-purpose drilling in metalworking environments and is typically used by machinists, maintenance technicians, and fabricators working across a broad range of materials.

This drill bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The steam oxide finish provides a measure of lubricity and heat resistance during cutting, making it appropriate for production and maintenance drilling tasks. The 10xD flute-to-diameter ratio and regular spiral type are optimized for through-hole and moderate-depth drilling applications in both shop and field settings. It is sold individually and meets ANSI standards.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or technicians familiar with drill press, CNC, or handheld power tool operation. Ensure the chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Appropriate cutting fluid or lubricant is recommended when drilling stainless steel, superalloys, or titanium to manage heat and extend tool life. Do not exceed the recommended maximum drilling depth of 3.3125 inches for this bit size.
