Why the Four-Facet Split Point Boosts Drilling Precision
One standout feature is the 118-degree four-facet split point. Think of it like the tip of a well-sharpened pencil that doesn’t slip when you press it down. This design allows the drill to start cutting immediately without wandering across the surface, which often happens with blunt or rounded tips. It leads to cleaner holes, less rework, and saved time—especially crucial when working on tough metals where every fraction of a second counts.
Installation and Maintenance Guide
Setting It Up
- Ensure the drill chuck is clean and free of debris before inserting the drill.
- Insert the drill securely to avoid wobbling during operation.
- Match the drill size to the material and hole diameter for optimal results.
- Set the drill speed according to recommended RPM for the material.
- Use cutting fluid to enhance tool life and improve finish when drilling metals.
Keeping It Going
- Regularly inspect the drill tip for wear or chipping.
- Sharpen or replace drills when dull to maintain cutting efficiency.
- Clean flutes after each use to avoid buildup and clogging.
- Store drills in a dry environment to prevent corrosion.
- Avoid excessive force to prevent tool breakage and extend life.
Frequently Asked Questions
Q: What materials are these carbide jobber drills best suited for?
They perform best on metal materials including mild steel, stainless steel, aluminum, and other alloys.
Q: What is the benefit of a four-facet split point?
It reduces walking at the start of drilling and helps produce more accurate holes.
Q: Can these drills be used in hand drills?
Yes, but they perform best in drill presses or CNC machines that maintain consistent speed and pressure.
Q: What speeds should I use with these drills?
Speeds depend on the material but generally slower speeds work best for carbide drill bits to extend life.
Q: What’s the difference between standard cut and double cut?
Standard cut is for softer metals, while double cut offers faster cutting on harder materials.
Q: How precise are these drills?
The tolerances are tight, with diameter held to +0.000 / -0.0005 for high accuracy.
Q: Do these drills require coolant or lubrication?
Using cutting fluid is recommended for metal drilling to reduce heat and improve bit life.
Q: How do I know when to replace the drill?
Replace when the bit becomes dull, chipped, or produces poor hole quality.
-
Q: How do I know when it’s time to Replace or Resharpen the burr?
Replace or Resharpen it when you notice decreased cutting efficiency or visible wear on the cutting edges.
