Types of Drill Bits Explained - Visual Guide for Wood, Metal & Masonry #315672 (License: Personal Use)

This illustration displays seven distinct drill bit types: twist, spade, masonry, countersink, step, auger, and Forstner bits, each rendered in precise black-and-white linework. The varying tip geometries-pointed, flat, chisel, and cross-cut-reflect their specialized functions across materials like wood, metal, and concrete. The shank styles and fluting patterns further differentiate their torque handling and chip ejection capabilities.
