Why the Four-Facet Split Point Makes Drilling Easier
The four-facet split point is like having a handy guide at the start of every hole you drill. Instead of your drill bit wandering or skidding on the surface, this design helps it grab on right where you want it. Think of it as a gentle tap that centers the drill for a clean entry, reducing the chance of slipping and giving you cleaner, more accurate holes every time.
