Snagg It Tip

For clean holes in porcelain and ceramic, use a guide template or masking tape over the drill point to prevent skating when starting the hole. Wet cutting with continuous water flow produces the cleanest results — run the drill at medium speed and keep steady, moderate pressure without forcing. For holes above 50mm, consider using a core drill stand rather than a handheld drill for improved control and accuracy, particularly in finished bathroom and kitchen tiling.
