Why the Four-Facet Split Point is a Game-Changer
The 118-degree four-facet split point might sound technical, but it basically means the drill starts drilling precisely without wandering. Picture trying to poke a hole with a sharp pencil versus a dull one — the sharper, well-designed split point bites into the metal exactly where you want, reducing that annoying walking effect and saving you from misaligned holes. This leads to cleaner cuts and less frustration on the job.
