Specialized Drill Bit Lexicon & Sourcing Guide

People often have a hard time finding 'core drills' because the terminology can be confusing, especially with 'masonry drills.' An illustrated online guide, like a 'Precision Driller's Lexicon,' would really help. This guide could clarify different types of drills—such as core drills, annular cutters, and step drills—using images and detailed descriptions. It could also explain their appearance, like the number of flutes or the step design, typical uses, shank types (e.g., Weldon), and the materials they are best suited for. Adding sourcing tips or links to reputable vendors would make it even more useful. This would save users a lot of time, reduce the chances of buying the wrong tool, and improve overall project efficiency by ensuring they get the right tool for the job.
