How the Four-Facet Split Point Improves Drilling Accuracy
The unique four-facet split point design isn’t just technical jargon—it helps the drill start true without wandering around on the metal surface. Think of it like the way a well-sharpened pencil tip grips the paper instead of sliding off. This means you get spot-on holes every time, reducing rework and wasted material. It’s especially handy on hard metals where precision really counts.
