Precision Twist Drill 5999214 Jobber Drill Bit 76 Hss

Product Description

The PRECISION TWIST DRILL 5999214 is a jobber-length drill bit designed for general-purpose drilling in metal and cast iron. It measures 0.02 inches (Wire Size 76) in diameter with an overall length of 0.875 inches and a flute length of 0.1875 inches. The bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish and features a 118-degree standard point angle with a web-thinned, tapered web configuration for improved center penetration. Right-hand spiral flutes clear chips efficiently during operation. Machinists, maintenance technicians, and metalworking tradespeople are the primary installers of this bit.

This bit is suited for drilling small-diameter holes in steel and cast iron in both shop and field settings. The straight-cylindrical shank seats directly into standard drill chucks without an adapter. Its general-purpose grade and ANSI-compliant construction make it appropriate for repetitive production work or precision maintenance tasks where tight hole tolerances at small diameters are required. The R18P series designation identifies it within the manufacturer's standard jobber-length line.

Key Features

• 0.02-inch diameter, Wire Size 76 for small-hole applications in metal
• 118-degree standard point with web-thinned, tapered web for reduced thrust at entry
• High-speed steel construction for durability across cast iron and steel workpieces
• Bright, uncoated finish suitable for use with cutting fluids or dry
• Right-hand regular spiral flutes for efficient chip evacuation
• ANSI-compliant construction to Series R18P standard

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks accepting straight-cylindrical shanks, for use in steel and cast iron workpieces.

Installation Notes

Install this bit into a properly sized drill chuck and tighten securely before operation. Always secure the workpiece with a vise or clamp before drilling to prevent rotation. When drilling small-diameter holes in hardened or abrasive materials, use appropriate cutting fluid and controlled feed pressure to avoid bit breakage. Inspect the cutting edges for wear before each use, as small-diameter bits are susceptible to breakage under side load.
