Why the Four-Facet Split Point Makes Your Drilling Smoother
That 118-degree four-facet split point isn’t just jargon—it's what really sets this drill apart. Think of it like a sharp chef’s knife designed to start cutting right where you want it, stopping that annoying bit of wandering when you begin a hole. The split point helps the drill bite into the material cleanly and centers itself, so you get precise holes without struggling to line things up.
