How the Four Facet Split Point Ensures Precision and Cleaner Starts
The four facet split point on these carbide drills is like a perfectly sharpened pencil tip—it helps the drill bite exactly where you want it without wandering off. This design reduces “walking,” meaning the drill won’t skate across your material’s surface when starting the hole. The result is an accurate, clean hole every time, saving you time from rework. It’s especially handy when working with harder metals where precision counts.
Installation and Maintenance Guide
Setting It Up
- Always verify drill size matches your project requirement before installation.
- Ensure the drill chuck is clean and secure to prevent slippage.
- Use appropriate speed and feed rates based on material type.
- Apply cutting fluid to improve cooling and chip evacuation.
- Check for any burrs on the drill tip before use to maintain accuracy.
Keeping It Going
- Regularly inspect for wear or dullness to maintain cutting performance.
- Clean flutes after each use to prevent chip build-up.
- Store drills in a protective case to avoid damage.
- Sharpen or replace drills promptly to avoid poor finish or breakage.
- Use correct coolant or lubricant to extend drill life and reduce heat.
Frequently Asked Questions
Q: What materials can these carbide jobber drills be used on?
They’re designed primarily for metals and alloys, including steel and stainless steel.
Q: What is the difference between standard cut and double cut?
Standard cut provides smooth cutting for softer metals; double cut offers more aggressiveness and chip clearance for harder materials.
