Why the Four-Facet Split Point Matters for Your Drilling
The four-facet split point design on these carbide drills helps the bit start more precisely without wandering, much like how a well-sharpened pencil point makes neat marks instead of smudges. This means less guesswork, cleaner holes, and a smoother drilling experience—especially important when working with hard metals where accuracy counts.
