Why the Four-Facet Split Point Makes a Difference
Ever noticed how some drill bits tend to wander or skid before the cut starts? That’s often due to blunt or rounded points. The four-facet split point on this drill bit acts like a precise guide that keeps the bit firmly where you want it from the get-go. Imagine it like using a sharp pencil instead of a dull crayon to draw a dot exactly where you want — the sharper point means better accuracy and less frustration.
