Precision Twist Drill 5998684 Jobber Drill Bit 13/32

Product Description

The PRECISION TWIST DRILL 5998684 is a jobber-length twist drill bit designed for general-purpose hole-making in a wide range of materials. Ground from high-speed steel with a steam oxide coating, it delivers reliable performance across production and maintenance drilling tasks. The 118-degree standard point angle suits most common drilling applications without requiring a pilot hole or center punch on flat stock. At 5.25 inches overall length with a 3.875-inch flute, this bit fits standard drill chucks and drill presses used daily by machinists, pipefitters, maintenance techs, and fabricators. The 13/32-inch diameter, equivalent to 0.4063 inches, covers a common bore size for pipe fittings, fastener clearance holes, and structural work.

This drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field environments. The Series R10 designation places it in the standard jobber-length family, making it a go-to choice for general fabrication, maintenance repair operations, and trade work where a reliable, consistent drill bit is needed without specialty geometry. The straight cylindrical shank seats directly in a standard keyless or keyed chuck with no adapter required.

Key Features

• 13/32 inch (0.4063 inch) diameter with matching straight cylindrical shank for secure chuck retention
• 118-degree standard point angle for general-purpose drilling across common metal types
• High-speed steel construction with steam oxide coating for improved lubricity and surface protection
• Right-hand cut spiral flute with regular spiral type for efficient chip evacuation
• Web-thinned tapered web reduces thrust and improves chip clearance at the cutting tip
• ANSI specification compliance for consistent dimensional tolerancing

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks accepting a 13/32 inch straight cylindrical shank. Suitable for use in handheld drills, drill presses, and milling machine setups. Primary workpiece material codes P, M, K, N, and S cover steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium.

Installation Notes

Install in a properly rated drill press or handheld drill with a chuck rated for the 0.4063-inch shank diameter. Secure the shank fully in the chuck before applying power. Use cutting fluid or coolant when drilling steel and stainless steel to extend tool life and prevent work hardening. Maximum drilling depth is 3.875 inches per the flute length; do not exceed flute length during through-hole operations without retracting to clear chips.
