How the Four Facet Split Point Boosts Your Drilling Accuracy
The 118-degree four-facet split point isn’t just a fancy phrase—it’s the secret behind easy starting and cleaner holes. Imagine trying to start drawing a circle with a pencil that keeps slipping. This special split point grips the surface like a steady hand, preventing the drill from wandering off target. For you, that means no more frustrating misaligned holes and smoother operation, especially on hard or slippery metals where precision matters most.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck securely clamps the shank without distortion.
- Check drill alignment with the workpiece before starting to avoid angled holes.
- Use recommended spindle speeds for carbide to prevent overheating.
- Apply appropriate cutting fluid to extend tool life and improve finish.
- Tighten collet or chuck firmly to avoid slippage during operation.
Keeping It Going
- Clean drills after use to remove metal chips and debris.
- Store in a protective case to avoid damage to cutting edges.
- Regularly inspect the drill point for wear and resharpen or replace as needed.
- Avoid excessive feed pressure to prevent tool breakage.
- Use fresh cutting fluids to maintain lubrication and cooling performance.
