How the Four-Facet Split Point Improves Your Drilling
Think of the four-facet split point as a specialty tip that acts like a sharp chisel, splitting the material rather than just grinding through it. This design reduces the tendency of the drill to wander or "walk" on the surface before it starts cutting. Imagine trying to put a key into a lock—the sharper and more precise the key, the easier it slides in. Similarly, this split point helps ensure your drill starts exactly where you want it, leading to cleaner, more accurate holes without the guesswork.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck is clean before insertion to maintain tight grip.
- Insert the Carbide Jobber Drill straight into the chuck for proper alignment.
- Tighten the chuck securely but avoid overtightening to prevent tool damage.
- Check that the drill size matches your material requirements before starting.
- Use appropriate cutting fluid to reduce heat and extend drill life.
Keeping It Going
- Clean the drill flutes after each use to prevent buildup of chips.
- Inspect the tip for dullness or chipping regularly and replace if needed.
- Store drills in a dry place to avoid corrosion.
- Use correct speed settings on your machine to optimize tool life.
- Sharpen or replace the drill as soon as you notice decline in cutting performance.

Q: What materials can these Carbide Jobber Drills be used on?
They are designed primarily for metalworking and excel on tough metals like stainless steel and cast iron.
Q: What is the difference between standard cut and double cut?
Standard cut has fewer cutting edges and is suited for softer metals; double cut has more edges and faster cutting rates for harder materials.
Q: What does the 118-degree split point mean?
It refers to the tip angle which helps reduce walking and improves drill positioning on the material.
Q: Can this drill be used in hand drills or only in drill presses?
While usable in hand drills, it performs best in drill presses or CNC machines that maintain steady speed and pressure.
Q: How do I maintain the drill bit to extend its life?
Use cutting fluid, clean chips regularly, and inspect for dullness or damage before use.
Q: What is flute length and why is it important?
Flute length is the cutting portion length of the bit; it determines how deep you can drill efficiently.
Q: What tolerance does this drill offer?
The drill diameter tolerance is Dia. +.000/-.0005, giving very precise hole sizing.
Q: Is this drill suitable for high-volume production?
Yes, with proper maintenance, it performs well in production environments requiring consistent quality.
