Precision Twist Drill 5999296 Wire Size 94 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999296 is a jobber-length drill bit sized to wire gauge 94, with a decimal diameter of 0.0071 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree split point, a two-flute spiral configuration, and a straight cylindrical shank. Overall length is 0.75 inches with a flute length of 0.0625 inches (1/16 inch) and a maximum drilling depth of 0.0625 inches. The web is tapered and web-thinned for improved chip evacuation at this micro-drill diameter. This bit is installed by machinists, tool-and-die workers, and precision trade technicians requiring accurate small-diameter hole generation.

The 5999296 is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It falls within the R10P-R15P-R18P series and is designed for general-purpose drilling applications where a standard-point micro drill is required. The straight cylindrical shank accepts standard collet chucks and drill presses configured for small-diameter tooling. Typical applications include precision hole placement in sheet metal, instrument components, and small-bore work in fabrication and machine shop environments.

Key Features

• Wire gauge size 94 with 0.0071 inch decimal diameter for micro-drilling applications
• High-speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• 118-degree standard point angle for general-purpose entry in hard and soft materials
• Two-flute spiral design with tapered, web-thinned web for improved chip clearance at small diameters
• Bright uncoated finish — no coating to alter critical diameter tolerances at this size class
• ANSI-compliant specification for consistent dimensional accuracy

Compatibility

Designed as a general-purpose jobber-length replacement drill bit in the PRECISION TWIST DRILL R10P-R15P-R18P series, compatible with any standard collet, chuck, or drill press toolholder accepting a 0.0071 inch straight cylindrical shank.

Installation Notes

Installation and use of micro-diameter drill bits should be performed by qualified machinists or trade technicians familiar with small-diameter tooling procedures. Secure the shank firmly in a collet or drill chuck rated for the diameter before operation, and verify runout is minimized to prevent bit deflection or breakage. Power down and de-energize any machinery before changing or inspecting the bit. At this diameter class, excessive feed pressure or off-axis force is the leading cause of breakage — use a drill press or precision spindle rather than a hand drill where possible.
