Why the Four-Facet Split Point Makes All the Difference
The 118-degree four-facet split point isn’t just tech talk—it’s your assurance that the drill starts clean and cuts efficiently without wandering. Think of it like having a sharp knife blade that’s precisely chamfered: it bites right into the material, keeping your drilling spot-on instead of skating around. This means faster drilling with less frustration, especially when working on difficult or hard-to-align surfaces.
