Why the Four-Facet Split Point Makes a Difference
Ever noticed how some drills tend to wander when you start? That’s where the four-facet split point shines. Think of it like the grip of cleats on a soccer field—it securely bites into the material so your drill stays on target. This design reduces walking on hard surfaces and creates cleaner holes first try, saving you time and frustration.
