Precision Twist Drill 5998242 Jobber Drill Bit 24 Hss

Product Description

The PRECISION TWIST DRILL 5998242 is a jobber-length drill bit in wire gauge size 24, equivalent to 0.1520 inches in diameter. Made from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a regular spiral flute geometry. The straight-cylindrical shank measures 0.1520 inches in diameter with a shank length of 1.125 inches and an overall length of 3.125 inches. This bit is designed for general-purpose drilling in ferrous and non-ferrous materials and is a standard shop tool for machinists, maintenance technicians, and fabricators who need reliable, consistent hole quality in production or repair applications.

This drill bit is suited for use in steel, cast iron, non-ferrous metals, superalloys, and titanium. Its jobber-length flute of 2 inches provides adequate reach for most standard drilling tasks without sacrificing rigidity. The right-hand cut, two-flute spiral design clears chips efficiently during through-hole and blind-hole operations. It fits standard drill chucks and is appropriate for use in drill presses, hand drills, and CNC applications requiring a straight-cylindrical shank. The bit carries ANSI specification compliance and is manufactured to the R10H-R18H series standard, making it a consistent choice for general shop use.

Key Features

• Wire gauge size 24, 0.1520-inch diameter for precise hole sizing
• High speed steel construction for durability across ferrous and non-ferrous workpiece materials
• 118-degree standard point angle with web-thinned, tapered web for easier penetration
• Two-flute regular spiral design with 2-inch flute length for efficient chip evacuation
• Bright uncoated finish suitable for general-purpose drilling without coolant-through requirement
• ANSI-compliant, R10H-R18H series construction for dimensional consistency

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks accepting a 0.1520-inch straight-cylindrical shank. Suitable for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium as part of routine machining, fabrication, and maintenance operations.

Installation Notes

This bit is installed by machinists or maintenance technicians into a keyed or keyless drill chuck rated for the shank diameter. Ensure the chuck is tightened securely and the workpiece is properly fixtured before beginning a drilling operation. Run at speeds appropriate for the workpiece material and bit diameter, and apply cutting fluid when working with harder ferrous materials to extend tool life. Inspect the cutting edges before use and replace the bit if chipping or dulling is present.
