Why the Four-Facet Split Point Boosts Drilling Accuracy
The 118-degree four-facet split point is a clever design that helps the drill bit bite into material with less walking or slipping on the surface. Imagine trying to place a sharp knife precisely on a slippery cutting board – if the tip is dull or blunt, it will slide, right? This split point acts like a sharp, pointed tip that anchors the drill bit exactly where you want it to go, resulting in cleaner, more accurate holes even when starting off slow or on tricky surfaces.
Installation and Maintenance Guide
Setting It Up
- Ensure drill chuck is clean and free from debris before installation
- Insert the carbide jobber drill fully into the chuck for maximum grip

Keeping It Going
- Regularly inspect drills for dullness or wear and replace as needed
- Keep drilling surfaces clean to avoid overheating and damage
