6. Operating Instructions
Follow these steps to sharpen your drill bits effectively:
- Prepare the Drill Bit: Ensure the drill bit is clean and free from debris.
- Turn On the Sharpener: Flip the ON/OFF switch to the "ON" position. The grinding wheel inside will begin to spin.
- Insert the Drill Bit: Locate the correct size hole on the installed sharpening head for your drill bit. Insert the drill bit into the hole.
- Adjust for Grinding: Gently push the drill bit down into the sharpening head until it makes contact with the grinding wheel. Rotate the drill bit slowly and evenly, applying light pressure. The foam rings can be used to help secure smaller bits and maintain the correct angle.
- Sharpen Both Flutes: Sharpen one flute of the drill bit, then remove it, rotate it 180 degrees, and sharpen the other flute. This ensures an even and balanced cutting edge.
- Check Sharpness: Periodically remove the drill bit and inspect its tip for sharpness. Continue sharpening until the desired edge is achieved. Avoid over-grinding, which can damage the bit.
- Turn Off the Sharpener: Once sharpening is complete, flip the ON/OFF switch to the "OFF" position and unplug the unit from the power source.
Note: For optimal results, practice with old or dull bits first to get a feel for the correct pressure and rotation technique. The adjustable degree of grinding allows for customization; experiment to find the best angle for your specific drill bit type (split-point or standard twist).
7. Maintenance
Regular maintenance ensures the longevity and performance of your drill bit sharpener.
- Cleaning: After each use, unplug the sharpener and use a soft brush or compressed air to remove any metal dust or debris from the sharpening heads and the main unit. Do not use water or liquid cleaners.
- Grinding Wheel Inspection: Periodically inspect the grinding wheels for wear. If a wheel appears excessively worn or damaged, it should be replaced. Replacement grinding wheels are specific to the small and large heads (WA8OL7 for large head, A8OL7 for small head).
- Storage: Store the sharpener in a clean, dry place, away from direct sunlight and moisture. Keep it out of reach of children.
- Power Cord: Inspect the power cord regularly for any signs of damage. If the cord is damaged, have it replaced by a qualified technician.
