How the Four-Facet Split Point Improves Drilling Accuracy
The 118-degree four-facet split point on these drills acts like a guide, helping the drill bite into the surface right where you want it. Think of it like the way a cat’s claws carefully grip onto a surface without slipping – this split point minimizes 'walking' or skidding when you start drilling, making your hole placement super precise. This design means less frustration and rework, which is a huge win if you’re working on tight deadlines or delicate materials.
