Hertel 71206429 Jobber Drill Bit Wire 25 Hss Oxide

Product Description

The HERTEL 71206429 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating for added wear resistance, this bit carries a wire gauge size of 25, equivalent to 0.1495 inches in decimal. The 118-degree standard point angle suits a wide range of common drilling applications. With a 3-inch overall length and a straight-cylindrical shank measuring 0.1495 inches in diameter, it fits standard drill chucks without adapters. The 2-flute spiral configuration with a tapered web and web-thinned point reduces walking on entry and improves chip evacuation.

This bit is suited for production and maintenance shops, metal fabrication environments, and general trade use where wire-gauge drill sizes are specified. The right-hand cut and regular spiral flute geometry make it a standard choice for drilling in mild steel, aluminum, brass, and similar materials. It is sold individually but requires a minimum order of 12 units, making it appropriate for shop replenishment stock. Licensed tradespeople and machinists working in HVAC, electrical, plumbing, and general fabrication will find this size commonly specified on job drawings.

Installation Notes

This drill bit is installed and used by machinists, electricians, pipefitters, and general tradespeople using standard drill presses or portable drills. Secure the shank fully in the chuck and verify chuck key is removed before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Follow applicable OSHA and facility safety standards for rotating cutting tool use, including appropriate eye protection.
