Hertel 71206007 Jobber Drill Bit Letter I Hss Oxide

Product Description

The HERTEL 71206007 is a jobber-length twist drill bit sized to Letter I (0.2720 inches decimal equivalent), designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide coating for added lubricity and surface protection, it features a standard 118-degree point angle and a two-flute regular spiral configuration with a web-thinned, tapered web for improved chip evacuation and easier starting. The straight-cylindrical shank measures 0.2720 inches in diameter, making it compatible with standard drill chucks. Installed by machinists, maintenance technicians, and general tradespeople, this bit covers a wide range of light-to-medium drilling applications.

This drill bit is suited for production and maintenance environments where Letter I sizing is required, such as tap drilling, clearance hole work, or general fabrication tasks. It fits into the 0.2500 to 0.3000 inch decimal size range, making it a practical choice for shops that need consistent, repeatable hole sizing in that bracket. The right-hand cutting direction is standard for conventional drill press and hand-drill operation. Each unit is sold individually.

Installation Notes

Install and remove drill bits only when the drill press or power tool is fully powered down and the chuck has stopped. Secure the shank fully into the chuck and tighten with a chuck key before operation. Use appropriate cutting fluid for metal drilling to extend bit life and improve finish quality. Always wear eye protection and follow applicable workplace safety standards when operating drilling equipment.
