Precision Twist Drill 5999292 Wire 93 Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5999292 is a wire gauge size 93 jobber-length drill bit manufactured from high speed steel (HSS) with a bright, uncoated finish. The bit measures 0.75 inches in overall length and carries a standard 118-degree split point angle with a web-thinned, tapered web design for cleaner entry and reduced walking on hard materials. Two spiral flutes with a regular helix and a flute-to-diameter ratio of 8xD support efficient chip evacuation during general-purpose drilling operations. This bit is suited for machinists, tool-and-die tradespeople, and maintenance technicians working in precision drilling applications at small diameters.

The 5999292 is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The 0.0075-inch diameter and 1/16-inch maximum drilling depth make it appropriate for fine-detail work, instrument assembly, printed circuit board fixturing, and similar precision tasks where a wire gauge drill is required. The straight-cylindrical shank accepts standard drill chucks. This bit falls within the Series R10P-R15P-R18P line and complies with ANSI standards for jobber-length drill geometry.

Key Features

• Wire gauge size 93, decimal diameter 0.0075 inches for fine-tolerance drilling
• 118-degree standard point angle with web-thinned tapered web for reduced thrust and cleaner starts
• High speed steel construction supports drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Bright uncoated finish suitable for general-purpose applications where coating is not required
• Two spiral flutes with regular helix promote chip clearing in shallow-depth holes up to 1/16 inch deep
• ANSI-compliant jobber-length geometry, Series R10P-R15P-R18P

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.0075-inch straight-cylindrical shank. Compatible with workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium as indicated by primary workpiece material codes P, M, K, N, and S.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, CNC machine, or hand-held drill with a compatible precision chuck. Secure the straight-cylindrical shank firmly in the chuck before operation to prevent slippage at this small diameter. At wire gauge sizes, low feed pressure and appropriate spindle speed are critical to avoid bit breakage. Always power down and lock out the machine before changing tooling.
