Designed for use by D-I-Yers, contractors and hobbyists on very hard or fragile materials such as porcelain tile, ceramic tile, stone, ceramics and glass. Diamond Core Drill Bits are premium specialty drill bits designed for drilling in hard abrasive non-ferrous materials. The electroplate bonded diamond drill bits have a superior design developed through extensive testing. Water is required for lubrication when drilling. Designed for drilling to depths of about ½”. (Not for use on metals, concrete, masonry, or with impact hammer drills). The patented DiamondSure bonded diamond drill bit fills a major gap in the current retail drill bit product lines. They are designed to be an inexpensive solution to cleanly and quickly drill in hard and fragile materials where no carbide or other retail drill bit is able.

Worked perfectly!
I needed to cut 1 hole in tile I'm installing in my shower so the shower head could connect. Worked perfectly! I would highly suggest creating a jig to hold the bit in place until it bites far enough to stay centered. I used a piece of 1X6 and drilled a 1 1/2" hole in it, clamped the board to the tile and went to work. Remember to keep water on the bit so it stays cool! Since I was working alone, I grabbed the water hose and barely cracked the water open. Just a little spray coming out the end did the trick. A little patience and preparation and the bit went through the tile like a knife through butter!

Works great on porcelain tile as advertised
Works great on porcelain tile as advertised. Just keep it wet, the weter the better. I used a piece of old plywood as a jig since the bit has no pilot drill.
