How the Four Facet Split Point Enhances Drilling Precision
Ever struggled with drills that wander or don’t start exactly where you want? Our carbide jobber drills come with a four facet split point at a 118-degree angle. Think of it like the difference between trying to cut paper with a dull scissor versus a fresh, sharp pair. The split point helps the drill bite into the metal immediately, preventing slipping and off-center holes. This means cleaner starts, less rework, and a professional finish every time.
Installation and Maintenance Guide
Setting It Up
- Secure the drill bit firmly in the chuck to prevent wobble.
- Ensure the drill press or handheld drill is set to proper speed based on metal type.
- Use cutting oil to reduce heat buildup and extend drill life.
- Align drill carefully to the center of the workpiece before starting.
- Wear safety glasses and gloves for protection.
Keeping It Going
- Clean chips and debris from the flutes regularly to avoid clogging.
- Inspect drill bits for wear or dull edges before each job.
- Store drills in a dry place to prevent rust or corrosion.
