|The Wixey WL133 Drill Press Laser projects a set of bright crosshairs onto your drill press table precisely where the drill bit center will contact your workpiece. This allows you to instantly position and clamp your workpiece in place so that the hole is drilled exactly where you want it. The laser even works with large diameter bits that are difficult to position without repeated test positioning. The Drill Press Laser mounts to most drill presses and is easily adjusted to align the crosshairs with the center of your drill chuck. The crosshairs will stay on center, even when changing your drill press table height and regardless of your workpiece thickness. Rugged steel construction stands up to normal vibration. Requires two AA batteries, which are not included.
