Why the Four-Facet Split Point Makes Your Drilling Smoother
The unique four-facet split point on this carbide drill helps the tool start drilling exactly where you want it. Think of it like the difference between using a pointed marker versus a blunt crayon—when the marker hits paper, it’s precise and controlled, whereas the crayon may slip or slide around first. This feature minimizes walking or wandering at contact, ensuring your hole is clean and exactly placed while lowering the effort needed to start the cut.
Installation and Maintenance Guide

- Check that the drill size matches your project needs.
- Use correct spindle speed based on material for smooth cutting.
- Ensure proper coolant or lubrication is applied during use.
- Double-check alignment before starting to avoid angled holes.
Keeping It Going
- Clean flute grooves regularly to prevent chip buildup.
- Inspect drill tips for wear or dullness before each use.
- Sharpen or replace drills when cutting efficiency drops.
