Why the Four-Facet Split Point Makes Your Drilling Smoother
The four-facet split point on this drill bit isn’t just a fancy design—it directly affects your drilling experience. Think of it like the difference between a blunt pencil and a freshly sharpened one; the split point creates a sharper tip that reduces walking (the drill slipping around) when you start the hole. This means you get more precise holes right from the get-go. Plus, it helps the drill slice through metal cleanly instead of tearing, which reduces heat buildup and prolongs bit life. So next time you’re drilling, just picture how crisp cutting edges help the bit glide through tough materials effortlessly.
Installation and Maintenance Guide
Setting It Up
- Secure the drill bit firmly in your chuck to avoid slipping during use.
- Ensure the bit's flute is clean for efficient chip removal.
- Match the drill speed to the material type for optimal performance.
- Use cutting fluid or coolant to prevent overheating on metalwork.
- Start drilling with light pressure to maintain accuracy and control.
Keeping It Going
- Regularly clean the drill bit after use to remove debris.
- Inspect the tip for dullness or chipping and replace if necessary.
- Sharpen carbide drill bits only with specialized equipment.
- Store bits in a safe place to avoid damage when not in use.
- Monitor drilling speed and pressure to prolong bit lifespan.

Q: What materials can these Carbide Jobber Drills be used on?
They’re designed primarily for metal, including hardened steel and other tough materials.
Q: What is the difference between standard cut and double cut?
Standard cut has fewer cutting edges for smoother holes, while double cut increases cutting speed on harder materials.
Q: What is the flute length and why does it matter?
The flute length is 4 inches, which helps evacuate chips and debris during drilling.
Q: How precise are these drills in terms of diameter?
The drills hold a tight tolerance of +0/-0.0005 inch, ensuring very accurate holes.
Q: Can these drills be sharpened?
Yes, but sharpening carbide drills requires specialized equipment and expertise.
Q: What is the helix angle, and why is 20 degrees used?
The 20-degree helix angle provides a balance between cutting speed and chip removal, ideal for metalworking.
Q: What is the advantage of the split point?
The 118-degree four-facet split point reduces walking and helps start holes quickly and accurately.
