Why the Four-Facet Split Point Makes a Difference
The four-facet split point design is the secret sauce that makes these drills so precise. Think of it like the tip of a well-sharpened pencil that guides your line exactly where you want it. This split point prevents the drill from wandering around when you start drilling, giving you a clean, perfectly centered hole every time—no frustrating slips or misalignments.
