Why a Four-Facet Split Point Makes a Difference
The 118-degree four-facet split point isn’t just fancy jargon—it’s the secret behind cleaner, more efficient drilling. Think of it like a well-sharpened pencil tip that lets you start writing smoothly without tearing the paper. This split point design cuts down on walking at the start of drilling and reduces the effort you need to keep the drill bit straight, giving you cleaner holes and less wear over time.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill chuck size matches the 8.50mm shank diameter for secure fitting.
- Check that your drill press or hand drill is set to the correct speed compatible with carbide drills.
- Clean the drill shank before installation to avoid slipping.

- Use cutting fluid where appropriate to extend drill life.
Keeping It Going
- After use, clean any metal debris off the flutes with a soft brush.
- Store drills in a dry place to prevent corrosion.
- Regularly inspect the split point and cutting edges for signs of wear or dullness.
- Sharpen drills when recommended or replace to maintain cutting efficiency.
- Avoid overheating by using proper feed rates and cooling during drilling tasks.
