Hertel 71205942 Jobber Drill Bit Letter C 118 Degree Hss

Product Description

The HERTEL 71205942 is a jobber-length twist drill bit sized to Letter C (0.2420 inches decimal equivalent), designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating, it offers basic wear resistance for everyday production and maintenance drilling. The 118-degree standard point angle suits flat and slightly curved work surfaces, and the web-thinned tip reduces entry force on harder materials. At 4 inches overall length with a 2.75-inch flute, it fits standard drill chucks and most benchtop or handheld drill presses used in trade and shop environments.

This bit is suited for maintenance technicians, pipefitters, electricians, sheet-metal workers, and general fabricators who need a reliable general-purpose jobber bit in the Letter C size. The straight-cylindrical shank accepts standard three-jaw chucks without modification. Its 0.2420-inch diameter falls within the 0.2000 to 0.2500-inch size range and is commonly used for clearance holes, pilot holes, and light production drilling on ferrous and non-ferrous materials.

Installation Notes

Install and remove drill bits only when the drill press or driver is fully powered down and the chuck is stationary. Secure the shank fully into the chuck jaws and tighten with a chuck key before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life. Eye protection is required during all drilling operations per standard shop safety practice.
