Why the Four-Facet Split Point Makes Drilling Easier
The four-facet split point on this jobber drill is like having a perfectly balanced arrowhead slicing through metal. Instead of wandering or walking when you start drilling, the split point centers itself instantly. This means fewer start errors and cleaner holes. Think of it like using a sharp pencil versus a dull one—the sharp, split point effortlessly bites into material, saving time and improving accuracy.
Installation and Maintenance Guide
Setting It Up
- Ensure drill chuck is clean and free of debris before inserting the drill
- Firmly secure the drill at the correct shank diameter to avoid slipping
- Set the drill speed appropriate for the job material to maximize tool life
- Use cutting fluid or lubricant to reduce heat and improve drilling quality
- Check alignment before starting to prevent wandering
Keeping It Going
- Regularly inspect the drill point for signs of wear or dullness
- Sharpen drills when you notice reduced cutting efficiency to extend tool life
- Clean flutes after use to prevent chip buildup and maintain performance
- Store drills in a dry, organized container to protect carbide edges
- Avoid excessive heat buildup by using proper feed rates and coolant
Frequently Asked Questions
Q: What materials are these drills best suited for?
They are designed primarily for metalworking, including steel, cast iron, and non-ferrous metals.
Q: What is the difference between standard cut and double cut?
Standard cut is best for softer materials; double cut provides faster cutting and better chip clearance on harder metals.
Q: Can these drills be used in automated drilling machines?
Yes, with the correct shank size and proper machine speed, they perform well in CNC and drill press setups.
Q: How does the split point affect drilling?
It prevents the drill from wandering at the start, improving accuracy and reducing surface damage.
Q: Are cutting fluids necessary when using these drills?
While not always required, using cutting fluids can extend the life of the drill and improve hole quality.
Q: What happens if I use the drill at too high a speed?
Excessive speed can cause overheating and premature wear, reducing tool life.
Q: Can these drills be resharpened?
Yes, with proper equipment, you can resharpen the split point to extend tool usability.
Q: What does the tolerance spec +.000 / -.0005 mean?
It indicates the diameter accuracy, meaning the drill's size won’t vary more than +0 / -0.0005 inch from nominal.
-
Q: How do I know when it’s time to Replace or Resharpen the burr?
Replace or Resharpen it when you notice decreased cutting efficiency or visible wear on the cutting edges.
