Why the 118-Degree Four-Facet Split Point Matters
Think of the split point like the sharp, pointed tip of a well-honed pencil, allowing you to start exactly where you want without wandering around. It helps the drill bite into the material cleanly, reducing walking on the surface. This means you get a more precise hole right from the get-go without needing to stop and reposition the drill. It’s especially useful when working with hard metals where accuracy and clean starts go hand in hand.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck is clean and free from debris before inserting the drill.
- Use the correct collet or chuck size to securely hold the 7.80mm drill.
- Check alignment to prevent wobbling during drilling.
- Select proper speed settings based on material hardness.
- Always wear appropriate personal protective equipment (PPE) when handling the drill.
Keeping It Going
- Regularly inspect the carbide tip for wear or damage.
- Clean the flutes after use to prevent buildup of drill shavings.
- Apply cutting fluid when drilling metals to reduce heat and extend tool life.
- Store drills in a protective case or holder to avoid damage.
- Replace drills once tolerances or cutting efficiency noticeably degrade.
Frequently Asked Questions
Q: What materials can these carbide jobber drills cut?
They are suitable for a wide range of metals and hard materials, providing precise and clean holes.
Q: What is the difference between standard cut and double cut?
Standard cut drills have a single set of spiral grooves, while double cut drills have two, improving chip breaking in tougher materials.
Q: How critical is the 118-degree split point angle?
It helps reduce walking on the material’s surface, offering better accuracy and cleaner starts.
Q: Can these drills be used in handheld drilling machines?
They are typically used in machine tools but can be used handheld if appropriate care and settings are applied.
Q: What does the tolerance +.000 / -.0005 mean?
It indicates the tight size variation allowed for the drill diameter, ensuring consistent hole sizes.
Q: How long will these carbide drills last?
Lifespan depends on usage and material; carbide provides improved durability over standard high-speed steels.
Q: What speeds and feeds are recommended?
Speeds and feeds vary with material; using cutting fluids and following manufacturer charts will help optimize performance.
Q: How important is the flute length?
Flute length affects chip evacuation and drilling depth; 60mm is suited for medium-depth holes.
