Precision Twist Drill 5999010 Wire 30 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999010 is a jobber-length drill bit sized to wire gauge 30, equivalent to 0.1285 inches in decimal. It is manufactured from high speed steel with a bright uncoated finish and ground to a standard 118-degree point angle. The two-flute spiral design with a tapered web and web-thinned point improves chip evacuation and reduces thrust at entry. With an overall length of 2.75 inches and a flute length of 1.625 inches, this bit is proportioned for close-tolerance work in metal fabrication, maintenance, and production drilling applications. Licensed tradespeople and machinists working in shop or field settings are the primary users.

This drill bit is suited for right-hand drilling operations in a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It fits any standard drill chuck or driver accepting a straight cylindrical shank of 0.1285 inches in diameter. The regular spiral and general-purpose grade make it a practical stock item for general production runs, maintenance shops, and toolroom use where a wire-gauge 30 hole is required without specialized tooling.

Key Features

• Wire gauge 30 size — 0.1285 inches decimal equivalent for precise hole sizing
• High speed steel construction for durability across ferrous and non-ferrous workpieces
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• Two-flute regular spiral geometry promotes efficient chip removal
• Bright uncoated finish — suitable for use with cutting fluid where required
• Straight cylindrical shank compatible with standard drill chucks

Compatibility

Designed as an OEM-style general-purpose replacement or stock drill bit for any standard keyed or keyless drill chuck accepting a 0.1285-inch straight cylindrical shank. Part of the PRECISION TWIST DRILL Series R10P-R15P-R18P family.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance mechanics using standard drill press, CNC, or handheld drilling equipment. Secure the shank fully in the chuck before operation and confirm the chuck is tightened and the spindle is at an appropriate speed for the workpiece material. Disconnect power or engage the machine lockout before changing bits. Do not exceed the maximum drilling depth of 1.625 inches in a single pass without retracting to clear chips.
