Precision Twist Drill 5999184 Wire 74 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999184 is a jobber-length drill bit sized to wire gauge 74, equivalent to 0.0225 inches in decimal, designed for precision drilling in tight-tolerance applications. Built from high speed steel (HSS) with a steam oxide coating, this bit handles heat and friction better than uncoated HSS in comparable operations. The 118-degree standard point angle suits general-purpose drilling across a wide range of workpiece materials. At 1 inch overall length with a 0.25-inch flute, it is intended for shallow-hole work where a compact, stiff tool is needed. Licensed tradespeople and machinists working in production or maintenance environments are the primary users of this tool.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The right-hand spiral flute with regular spiral type and tapered web configuration supports efficient chip evacuation in short-depth holes. Web-thinned geometry at the point reduces thrust force on entry, which matters when working in thin-gauge stock or close to part edges. The 11xD flute-to-diameter ratio is standard for jobber-length bits of this size class, making it a practical daily-use option in a drill press or hand drill setup.

Key Features

• Wire gauge 74 size, 0.0225 inches decimal diameter for precision small-hole work
• High speed steel construction with steam oxide coating for improved heat and wear resistance
• 118-degree standard point angle for general-purpose drilling across multiple material types
• Right-hand cut with spiral flute and web-thinned, tapered web for reduced entry thrust
• Straight-cylindrical shank, 0.0225 inches diameter, compatible with standard collets and chucks
• ANSI standard compliance, Series R10-R15-R18 designation

Compatibility

Designed as a general-purpose OEM-style jobber-length drill bit suitable for use in drill presses, CNC machines, and hand drills accepting straight-cylindrical shanks at 0.0225 inches diameter.

Installation Notes

This bit is installed and used by machinists, tool-and-die workers, and maintenance technicians. Secure the straight-cylindrical shank firmly in a properly sized collet or chuck before operation to prevent runout. Maximum drilling depth for this bit is 0.25 inches; do not exceed this depth without retracting to clear chips. Always power down and lock out the machine before changing bits.
