Warm Tips:

Usage Tips for Vacuum Brazed Diamond Core Bits 1. Do not use these drill bits with a hammer drill

2. Install these drill bits only on a corded drill, not a cordless drill (not enough power).

3. Only for drilling tiles, not recommended for the material behind the tile.

4. For horizontal drilling, simply apply light pressure; for vertical drilling, the weight of the machine will provide sufficient pressure.

Start drilling according to the following instructions:

1) Position the drill at a 45-degree angle.

2) Drill until the hole begins to form.

3) Bring the drill to a vertical position.

4) Continue drilling and swing the machine in a circular motion.
