How to use:
Mark the position for the hole that needs to be drilled on the material being worked. Place the drill guide into position taking care to line up the required hole size on the front guide plate, with the positioning mark for the hole you have made previously. Push the drill guide on to the surface until the suction cup is flat and then the push the centre level down to engage suction pad. Check that the guide has adhered to the surface before commencing drilling.
When working in hard materials such as ceramic tiles in can be advantageous to lubricate the drill bit using water. To do this pour water into a hole near the top of the guide the EVA pad will retain the water and help lubricate the bit when drilling. Always ensure that the guide is firmly stuck to the surface and that you have selected the correct size drill bit before you begin drilling. Drill at a low speeds when working in hard products.
