Drilax 1 34 Inch Diamond Hole Saw Drill Bit Ceramic, Porcelain Tiles, Glass, Granite Counter top Shower, Faucet Size 1-34

The Drilax 1-3/4 inch diamond hole saw drill bit is suitable for drilling through ceramic, porcelain tiles, glass, granite countertop, shower, and faucet. The drill bit does not require an arbor and can be used with a standard electric or cordless drill. It is capable of drilling multiple holes before needing another drill bit when used carefully. Customers confirm that it works well on aquarium glass, but not on acrylic. Some suggest using a wooden template to guide drilling of granite. Reviews show mixed results on the longevity of the bit and its diameter cutting size, which is slightly over 1-3/4". However, it worked well for drilling holes in porcelain and granite, creating clean cuts with no sharp edges.
