How the Four-Facet Split Point Improves Your Drilling Accuracy
At first glance, the split point on your drill might just seem like a fancy tip shape, but it makes a huge difference. Imagine trying to start a hole with a dull nail versus a sharp needle—the split point acts like that needle, helping the drill bite into the material cleanly without wandering or slipping, especially on hard metals. The four facets give the drill multiple cutting edges, which balance pressure and reduce walking, allowing you to hit the mark quickly and keep your holes tight and true.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill chuck is clean and free of debris before installation.
- Match the shank diameter of the drill to your chuck size for a tight grip.
- Insert the drill fully to prevent wobble or slippage during operation.
- Check that your drill press or machine is set to the correct speed for carbide tools—usually slower than high-speed steel drills.
- Tighten the chuck securely but avoid overtightening which can damage the tool.
Keeping It Going
- Clean the flutes and drill tip regularly to remove chips and prevent clogging.
- Use cutting lubricant appropriate for metals to reduce heat and extend tool life.
- Avoid applying excessive pressure; let the drill do the work for smoother cuts.
- Inspect the drill periodically for chipping or dullness and replace when performance degrades.
- Store drills in a dry place to prevent rust or corrosion on shanks.
Frequently Asked Questions
Q: What materials can these Carbide Jobber Drills cut?
They are designed to handle a wide range of metals, including stainless steel, aluminum, and other hard alloys.
Q: What is the difference between Standard Cut and Double Cut?
Standard Cut drills have a simpler cutting edge for general drilling, while Double Cut drills have additional intersecting cuts that improve removal of chips and speed.
Q: What drill speeds are recommended for these carbide jobber drills?
Slower speeds than high-speed steel drills are best—usually between 100-300 SFM (surface feet per minute), depending on your material.
Q: How important is the split point feature?
It reduces walking at the start of drilling, improving accuracy, especially in hard or tough materials.
Q: Can these drills be used in handheld drills?
They’re best suited for drill presses or CNC machines for stability and precision, but can be used with careful control in handheld drills.
Q: How do I know when to replace these drills?
Signs include reduced cutting speed, poor hole finish, or visible chipping on the cutting edges.
Q: Are these drills compatible with cutting fluids?
Yes, using cutting fluids is recommended to extend tool life and improve performance.
Q: What does the tolerance +.000/-.0005 mean?
It means the drill diameter is held to within plus zero and minus 0.0005 inches, ensuring precise hole sizing.
