Why the 118-Degree Four-Facet Split Point Matters
Think of the split point on this drill bit like the tip of a pencil that’s sharpened in a special way. Instead of just a simple point, the four facets create multiple sharp edges that help the drill start cutting immediately without sliding around on the surface. This ‘self-centering’ feature means you don’t have to spend extra time marking the spot or worrying about the drill wandering off target. It’s like having training wheels on a bike until you gain perfect balance—making those first holes clean, quick, and precise every time.
