Why the 118-Degree Four Facet Split Point Makes a Difference
Ever noticed how some drill bits tend to wander before they bite in? That’s often due to the point design. Our Carbide Jobber Drills feature a Four Facet split point angled at 118 degrees, which acts like a built-in pilot bit. This design centers the drill quickly and keeps it steady as you work. Think of it like using a pencil tip to mark a target before shooting an arrow—it makes sure you’re right on point every time, leading to cleaner holes and less material damage.
Installation and Maintenance Guide
Setting It Up
- Ensure your drill chuck matches the diameter (4.7 mm) for a tight fit.
- Clean the shank before installation to improve grip and reduce slippage.
- Insert the drill fully into the chuck and tighten securely, preferably with a chuck key.
- Confirm the drill’s alignment for straight drilling paths.
- Choose the appropriate speed settings on your drill based on material hardness.
Keeping It Going
- Regularly clean the drill bit to remove metal shavings and debris.
- Use cutting oil or lubricant when drilling harder metals to prolong bit life.
- Inspect the cutting edges often—replace bit when dull to maintain precision.
- Store bits in a dry, secure place to prevent damage and corrosion.
- Avoid overheating by pausing drilling on tough materials to reduce wear.
