Helpful Tips:

Using Vacuum Brazed Diamond Core Drill Bits 1. Do not use these drill bits in hammer mode.

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

3. For drilling tile only, not recommended for the material behind the tile.

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

Start drilling by following these 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 along a circle.
