Why a Four-Facet Split Point Improves Drill Accuracy
Let’s say you’re trying to start a drill hole, but it keeps wandering on the surface—that’s drill walking. Our Carbide Jobber Drills feature a 118 degree four-facet split point, which acts like a pilot guiding your drill bit right where you want it. Imagine trying to stab a pencil cleanly into a corkboard—the sharper and more pointed it is, the steadier it stays. These facets reduce that wandering, make starting holes easier, and improve your overall precision. It's like having a friendly helper steadying your hand!
