Precision Twist Drill 5999180 Jobber Drill Bit 0.024 in

Product Description

The PRECISION TWIST DRILL 5999180 is a jobber-length twist drill bit designed for general-purpose drilling in ferrous materials including cast iron and steel. The bit measures 0.024 inches in diameter, corresponding to wire gauge size 73, with a 118-degree standard drill point angle and a web-thinned, tapered web configuration that reduces entry resistance. The spiral flute geometry and oxide finish are standard for high speed steel tooling used in production and maintenance drilling applications. Right-hand cut with a straight-cylindrical shank, this bit fits standard drill chucks without modification.

This bit is suited for light-duty drilling tasks in metalworking, HVAC fabrication, plumbing rough-in, and electrical trade applications where small-diameter pilot holes or clearance holes are required in steel or cast iron workpieces. The Series R18 designation places it within the Precision Twist Drill general-purpose jobber-length line, which conforms to ANSI standards. With an overall length of 1.125 inches and a flute length of 0.3125 inches, it is appropriate for use in benchtop drill presses, hand drills, and drill stations handling fine-gauge work.

Key Features

• 0.024 inch diameter, wire size 73, for small-diameter drilling in steel and cast iron
• 118-degree standard drill point for general-purpose entry into ferrous materials
• High speed steel construction with oxide finish for wear resistance
• Web-thinned, tapered web reduces thrust and improves chip clearance
• Right-hand spiral flute, straight-cylindrical shank fits standard drill chucks
• Conforms to ANSI standards, Series R18 general-purpose grade

Compatibility

Designed as an ANSI-compliant general-purpose jobber-length drill bit suitable for use in standard drill chucks and drill presses handling wire-gauge diameter tooling in ferrous material applications.

Installation Notes

Install in a properly rated drill chuck and verify the chuck is fully tightened before operation. At this diameter, use low feed pressure to avoid bit deflection or breakage. Secure the workpiece firmly before drilling. Follow applicable shop safety practices and wear appropriate eye protection when operating rotary cutting tools.
