How the Four-Facet Split Point Improves Your Drilling Accuracy
The 118-degree four-facet split point might sound technical, but think of it like a well-designed sneaker sole that grips a slippery surface better. This point reduces the chance of the drill wandering or "walking" when you start drilling. It bites into the material cleanly and helps keep your drill bit exactly where you want it. This means fewer mistakes, cleaner holes, and less guesswork—perfect for those precision metalworking jobs.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill press or hand drill is securely mounted before inserting the bit.
- Check the chuck size to match the drill diameter for a snug fit.
- Insert the carbide jobber drill fully into the chuck and tighten firmly to avoid slippage.
- Use appropriate cutting speed settings based on material (usually slower for carbide tools).
- Wear safety gear like goggles and gloves before starting drilling work.
Keeping It Going
- Clean the drill bit after each use to remove metal shavings and debris.
- Use cutting fluid when drilling metals to reduce heat and extend tool life.
- Inspect for wear or chipping and replace the bit if cutting becomes uneven.
- Store the drill bits in a dry, organized case to prevent damage and corrosion.
- Sharpen only if you have the proper equipment or professional service, as carbide requires special tools.
Frequently Asked Questions
Q: What materials are these carbide jobber drills best for?
They are designed mainly for drilling a wide range of metals including stainless steel and hardened alloys.
Q: What is the significance of the 118-degree split point?
This angle reduces walking during the start of drilling and improves hole accuracy.
Q: Can I use these drills with a handheld drill?
Yes, as long as the handheld drill’s chuck can securely hold the diameter and length of the jobber drill.
Q: How do I maintain the sharpness of the carbide drills?
They require professional sharpening or special equipment as carbide is a hard material.
Q: What cutting speeds should I use?
Use slower speeds and adequate coolant when drilling metals with carbide tools to avoid overheating.
Q: What does the tolerance +.000/-.0005 mean?
It means the drill diameter is highly precise; it will vary only within 0 to -0.0005 inches.
Q: What is the flute length used for?
The flute length determines the depth of cut and helps in chip removal during drilling.
Q: Are these drills suitable for wood or plastics?
They are specialized for metalworking and are not recommended for wood or plastic drilling.
