Increased output by 35% while reducing tooling costs.
Why the Four-Facet Split Point Enhances Your Drilling Accuracy
The four-facet split point on these drills is like having four tiny scalpel edges that help the bit bite into material with greater precision. Imagine trying to stab a pencil into a stubborn spot – if the point is blunt, it slips and slides. But with a split point, the drill starts cleanly without wandering. This reduces the chances of crooked holes and keeps your work consistent, especially on tough metals where precision is key.
Installation and Maintenance Guide
Setting It Up
- Check your drill press or handheld drill compatibility with 0.021" tool diameter.
- Secure the carbide jobber drill firmly in the chuck to avoid slipping during operation.
- Set the proper speed for carbide drills – generally slower than HSS drills to prevent overheating.
- Use cutting fluids to extend tool life and improve performance.
- Ensure the workpiece is clamped securely to prevent moving during drilling.
Keeping It Going
- Regularly clean the drill flutes to prevent clogging and heat buildup.
- Inspect the cutting edges for wear or chipping before each use.
- Store drills in a dry place to avoid corrosion or damage.
- Sharpen carbide drills with appropriate equipment or replace when worn down.
- Use appropriate feed rates to avoid excess stress on the drill.
Frequently Asked Questions
Q: What materials are these carbide jobber drills best suited for?
These drills are ideal for hard metals and alloys, offering precision and durability on tough materials.
Q: What is the drill tolerance, and why is it important?
The tolerance is diameter +.000/-.0005, meaning hole sizes are very precise, essential for tight fits.
Q: Can these drills be resharpened?
Yes, with the right equipment carbide drills can be resharpened to extend their life.
Q: What is the significance of the four-facet split point?
It reduces walking on the material, allowing for accurate and clean hole starts.
Q: What speeds should I use with carbide drills?
Carbide drills typically run at slower speeds than high-speed steel to avoid overheating.
Q: Are these drills compatible with standard chucks?
Yes, they fit most standard drill chucks designed for small diameter tools.
Q: How long is the flute length?
The flute length is 1/4", perfect for shallow to medium depth holes.
Q: What does the 20-degree helix angle do?
It helps with chip removal and reduces cutting forces for smoother drilling.
