Why the Four Facet Split Point Makes a Difference
If you’ve ever struggled with drills slipping or wandering on hard materials, the four facet split point is designed to keep your drill exactly where you want it. Think of it like the grip on your favorite hiking boot—it steady’s your foot on tricky terrain. This split point design not only helps the drill start quickly without skidding around, but also reduces pressure and heat build-up, so your tool wears out slower and cuts cleaner.
