Sermderm Diamond Hole Saw Kit for Tile, Glass, Ceramic, Granite & Marble | 15-Piece Set with Double Suction Cups

• Precision Cutting for Hard Surfaces — Diamond-tipped bits cut glass, porcelain, ceramic, granite, and marble smoothly. Ideal for precise installations in bathrooms and kitchens where accuracy is key.
• Enhanced Stability with Suction Cups — Double suction cups secure the drill guide to the material surface, preventing wobble and ensuring clean, centered holes. Reduces risk of material cracking.
• Durable Diamond Coating — The diamond grit coating on the drill bits offers superior hardness and wear resistance, allowing for extended use on tough materials compared to standard hole saws.
• Versatile 15-Piece Set — Includes a range of bit sizes and a drill guide, suitable for various hole diameters needed in tiling, plumbing, and decorative stone work projects.

• Prepare the Surface and Drill — Clean the target surface. Attach the double suction cups to the drill guide and press firmly onto the material where the hole is needed. Ensure your drill is set to a low speed and use the straight shank arbor with the correct pilot bit.
• Begin Drilling — Position the pilot bit in the center of the desired hole. Slowly begin drilling at a low RPM, applying steady, even pressure. Keep the drill perpendicular to the surface to ensure a clean cut and prevent the bit from binding.
• Cut and Finish — Continue drilling, periodically clearing debris and applying water or a lubricant if cutting very hard materials like granite to keep the bit cool and extend its life. Once the cut is complete, carefully remove the drill and the cut-out piece.
