How the Four-Facet Split Point Ensures Sharp Starts
The four-facet split point on this drill tip acts like a self-centering guide, minimizing the common problem of drill wandering when you start your hole. Think of it as the difference between trying to start a screw with a dull driver versus a brand-new one — this tip bites right in and keeps your drill aligned so you get holes exactly where you want them, right from the first touch.
