Why the Four Facet Split Point Makes Drilling Effortless
Ever had a drill bit that just wouldn’t start in the right spot? This drill’s 118-degree four facet split point acts like a starter guide. Imagine it like the pilot light on a stove—igniting the drill’s cutting edge exactly where you want it. This helps prevent the bit from wandering across the work surface, giving you precisely placed holes every time with less effort. It’s great for both novices and pros who value clean starts and accurate results.
