Why the Four-Facet Split Point Improves Your Drilling
The 118-degree four-facet split point on this carbide jobber drill is like having a smart guide for your drill bit. Instead of wandering around as you start the hole, this point design pinpoints the exact drilling location and cuts with less force. Imagine starting a perfect circle with a pencil, where the tip doesn't slip—this feature does just that for your drill, ensuring smoother, cleaner holes every time. It also means you won’t need to apply extra pressure or risk damaging delicate materials.
