How the Four-Facet Split Point Improves Your Drilling
The four-facet split point essentially means the drill tip is ground into four distinct cutting edges instead of the usual two. Imagine trying to push a sharp pencil through tough cardboard versus one with multiple smaller points pushing through smoothly. This design helps reduce the drill's tendency to wander or "walk" when starting a hole, resulting in precise entry points and cleaner, more accurate holes. It's like having a guide rail built right into your cutting tool!
Installation and Maintenance Guide
Setting It Up
- Ensure the drill press or handheld drill is powered off before installation.
- Select the correct chuck size to securely grip the 0.1820 inch shank.
- Insert the drill bit straight into the chuck and tighten firmly to avoid slipping.
- Confirm the drill speed settings match the material to optimize cutting.
- Wear safety glasses and gloves while handling and installing the drill bit.
Keeping It Going
- Regularly inspect the drill tip for wear and dull edges to ensure clean cuts.
- Clean the flute channels after each use to prevent chip buildup.
- Use cutting fluid or lubricant where appropriate to extend tool life.
- Store bits in a dry, organized case to prevent damage or corrosion.
- Replace bits promptly when signs of chipping or decreased performance appear.
Frequently Asked Questions
Q: What materials can these carbide jobber drills handle?
They are ideal for drilling various metals including steel, aluminum, and alloy materials.
Q: What is the difference between standard cut and double cut?
Standard cut has fewer cutting edges for general use, while double cut drills offer faster cutting and smoother finishes on harder materials.
Q: Can these drills be used on a handheld drill?
Yes, but ensure the drill chuck is compatible with the 0.1820" shank for secure fastening.
Q: How does the split point help with drilling accuracy?
The four-facet split point reduces walking at the start of drilling which helps with precise hole positioning.
Q: What speed should be used with these drills?
Speed depends on material; lower speeds for hard metals and higher speeds for aluminum are generally recommended.
Q: Are these drills resharpenable?
Yes, carbide drills can typically be resharpened by a skilled professional to extend tool life.
Q: What length are the flutes?
The flute length is 1-5/8 inches providing adequate depth for most jobber drilling tasks.
Q: Do these drills require coolant?
Using cutting fluid is recommended especially when drilling harder metals to reduce heat and prolong bit life.
-
Q: How do I know when it’s time to Replace or Resharpen the burr?
