Why the Four Facet Split Point Makes a Difference
Think of the four facet split point as the drill’s starting pistol—it's designed to make sure your drill bites into the surface exactly where you want it. Traditional points can wander or skate over tough surfaces, but the split point ‘grabs’ the material and keeps the bit steady. It’s like the difference between slipping on ice and having firm footing. This precision minimizes walking and increases accuracy, saving you time and material by reducing mistakes.
