Increased production quality by 35% while reducing waste and tool replacement frequency.
Why the Four-Facet Split Point Guarantees Better Starts Every Time
The four-facet split point might sound complex, but it simply means that the drill's tip is designed to 'self-center' without slipping or wandering across your workpiece. Imagine trying to draw a perfect circle freehand versus using a compass—this split point acts like a compass needle, keeping your drill bit exactly where you want it from the moment it touches the surface. This results in cleaner holes, less rework, and saves you time on every project.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill chuck is clean to avoid slippage.
- Insert the drill shank fully into the chuck and tighten securely.
- Select appropriate speed settings based on material hardness (lower speeds for hard metals).
- Use a center punch to mark drill spots for precision starts.
- Always wear safety goggles to protect from flying chips.
Keeping It Going
- Regularly inspect the drill for wear and chipping.
- Use cutting fluid to extend drill life and improve finish.
- Clean flutes after every use to prevent clogging.
- Store drills in a protective case to avoid damage.
- Sharpen or replace worn drills promptly to maintain quality results.
