Understanding the Four Facet Split Point and Why It Matters
The 118-degree four-facet split point might sound like a mouthful, but here’s the gist: this specialized tip design helps the drill bite into the material right away and prevents it from wandering or “walking” on the surface. Think of it like having four sharp corners that guide the drill straight down, just like a skilled arrow hitting the bullseye every time. This means cleaner holes and less wasted material, saving time and frustration for any project.
Installation and Maintenance Guide
Setting It Up
- Secure the carbide jobber drill firmly into a compatible chuck—ensure proper fit to avoid wobble
- Check that the drill bit is clean and free of debris before use
- Use the appropriate speed settings based on material type to maximize tool life

- Test on scrap material for proper alignment and cutting performance
Keeping It Going
- Inspect the drill bit regularly for wear or chipping, especially the tip
- Keep the tool clean and dry after each use to prevent corrosion
- Use sharpening services or replace the bit once drilling quality diminishes
