User tips: Mark the tile and place the drill tip at a 45-degree angle Start drilling and level the drill once the tile surface is scored Drill using a slight oscillating motion until the hole is complete Do not use unnecessary pressure, the weight of the machine is sufficient Use at speeds between 800 - 2000rpm For harder tiles use a slower rpm / for softer tiles use a faster rpm Suitable for use on: Ceramic tiles Granite tiles Limestone tiles Marble tiles Porcelain tiles Slate tiles
