Why the Four-Facet Split Point Improves Drilling Accuracy
The four-facet split point design on these drills acts like a precision compass needle guiding your hole-making process. Instead of wandering or slipping when you begin drilling, this point ensures the bit stays exactly where you want it, dramatically reducing errors. It’s like having a spot-on aiming guide that guarantees your holes are neat and centered right from the start, saving time and material.
