Why the Four-Facet Split Point Makes Your Drilling Smoother
One feature that often flies under the radar but makes a huge difference is the 118-degree four-facet split point. Imagine trying to start a hole with a blunt pencil versus a sharpened one—the split point acts like that sharpened tip. It reduces walking (the unwanted lateral movement when you start drilling), so your drill bit stays right where you want it.
This means cleaner, more accurate holes with less need to reposition or fix errors, saving you time and frustration during every job.
Installation and Maintenance Guide
Setting It Up
- Check that your drill chuck securely fits the 0.0465-inch diameter shank.
- Ensure the drill presses or hand drills are clean and free of debris before installation.
- Insert the carbide jobber drill fully and tighten chuck firmly but without over-tightening.
- Set the proper speed based on material to avoid overheating.
- Double-check alignment before starting your drilling operation.
Keeping It Going
- Use appropriate cutting fluids to extend drill lifespan and improve finish.
- Clean chips and debris frequently to prevent wear or clogging.
- Store drills in a dry place to avoid corrosion or damage.
- Inspect for dullness or chips regularly and replace if any imperfections appear.
- Avoid overheating by using proper feed rates and speeds; overheating harms carbide tips.
Frequently Asked Questions
Q: What materials are these carbide jobber drills suitable for?
They work best on metals including stainless steel, aluminum, and other hard materials due to carbide's toughness.
Q: What does the 118-degree four-facet split point do?
This tip design helps reduce drill walking and allows for precise hole starting without a pilot hole.
Q: What’s the optimal speed for drilling with these tools?
Speed depends on material, but generally slower speeds with coolant work best to prevent overheating.
Q: Can these drills be resharpened?
Yes, but it’s recommended to have a professional service the carbide tips to maintain geometry and performance.
Q: What is the tolerance range on diameter sizes?
The drills are manufactured to a tolerance of diameter +.000/-.0005 for precision work.
Q: How do I prevent the drill from overheating?
Use proper feed rates and keep cutting fluids applied during operation.
Q: Are these compatible with handheld drills?
Yes, as long as the drill chuck accepts the 0.0465-inch shank diameter securely.
Q: What's the advantage of a 20-degree helix angle?
It helps in efficient chip removal and reduces heat buildup during drilling.
