How the 118° Four-Facet Split Point Boosts Your Drilling Accuracy
The four-facet split point on these drills means the tip is shaped to cut precisely and start drilling without wandering. Imagine trying to poke a hole in a balloon with a sharp needle versus a dull one; the sharp needle goes exactly where you want it every time. This design ensures the drill starts immediately and drills clean holes without slipping or creating oversized openings. It’s like having a guaranteed aiming system for every cut you make, saving time and giving you consistent results.
