How the Four-Facet Split Point Drill Improves Accuracy and Control
The 118-degree four-facet split point on this jobber drill is like having a smart guide that helps the drill bit start exactly where you want it. Imagine trying to drill on a slippery surface—without that precise point, your bit can wander, making your hole off-center. This split point design cuts into the material cleanly without wandering, so you get crisp, accurate holes every time, saving you from frustrating misdrills and extra clean-up.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill chuck matches the 7.00 mm shank diameter for a secure fit.
- Clean the drill chuck before inserting to avoid slippage during use.
- Confirm the correct rotation direction before starting your drill press or hand drill.
- Use cutting fluid for metals to reduce heat and prolong drill life.
- Start drilling at low speeds until the bit bites in well, then increase as needed.
Keeping It Going
- Clean drill bits after each use to remove metal shavings and buildup.
- Sharpen or replace drills when you notice excessive heat or slower cutting speeds.
- Store in a dry place to prevent corrosion.
- Use proper cutting fluids continuously during metal drilling to avoid premature wear.
- Inspect drill for chips or cracks before each use to ensure safety.
Frequently Asked Questions
Q: What materials can these Carbide Jobber Drills handle?
They’re designed primarily for metalworking, including steel, stainless steel, and aluminum, though they can also be used on some alloys.
Q: What is the difference between standard cut and double cut?
Standard cut has fewer cutting edges for smoother, precise drilling, while double cut has more edges for faster cutting on tougher materials.
Q: Why is the 118-degree four-facet split point important?
It helps the drill start smoothly without wandering, resulting in more accurate holes and less rework.
Q: What drill diameter tolerance should I expect?
The diameter tolerance is extremely tight at +0.000 / -0.0005 mm, perfect for precision work.
Q: How do I know if the drill fits my machine?
The shank diameter matches 7.00 mm, so check your drill chuck compatibility before purchasing.
Q: Can I use cutting fluid with these drills?
Yes! Applying cutting fluid is recommended to reduce heat and prolong tool life, especially when drilling metals.
Q: Are these drills suitable for hand drilling?
They can be used with hand drills but work best in drill presses or CNC machines for precision.
Q: What is the overall length of the drills?
They have an overall length of 89 mm with a flute length of 54 mm, ideal for standard drilling depths.
