Starting a hole saw on polished porcelain or glass is the moment everything can go wrong — the bit skates across the surface and scratches the tile before it bites. The BIHUI metal hole drill guide stops that. It holds the bit centered so it can't wander, and a suction cup anchors the guide firmly to the tile so it stays put while you start the cut.
Adjustable openings accept a variety of hole-saw sizes, and a rigid metal frame keeps everything steady for accurate, clean holes in tile and glass. Pair it with diamond drill bits for skate-free starts on the slickest surfaces.
Pro tip: Clean the tile where the suction cup lands and confirm it's locked before you drill. Start with light pressure and water to let the bit bite cleanly through the glaze, then ease into the cut.
