The EAGLE CUTTING TOOL J102-202-D is a Letter B high-speed steel (HSS) jobber-length drill bit manufactured in the USA. Jobber-length drills are the standard flute-length format used across general-purpose drilling in metal, wood, and plastic. The HSS construction provides the hardness and heat resistance required for production drilling in ferrous and non-ferrous materials. Weighing 0.15 pounds, this is a single-piece drill bit suited for use in handheld drills, drill presses, and CNC setups where a Letter B diameter is specified.
Letter B jobber drills are a common size in HVAC, plumbing, and electrical trade work, used for pilot holes, sheet metal penetrations, conduit knockout prep, and general fabrication tasks. USA manufacture indicates compliance with domestic tooling standards, making this bit appropriate for contractors and shops that specify domestic tooling for quality consistency or procurement requirements.
Designed as a standard Letter B HSS jobber drill for use in any 3-jaw chuck or collet system that accepts jobber-length drill bits of the corresponding shank diameter.
Install and remove drill bits only with the drill or drill press powered off and the chuck fully secured. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Ensure the workpiece is clamped securely before drilling to prevent movement. Worn or damaged bits should be replaced rather than reused to avoid workpiece damage or injury.
