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.

Tried to drill a quartz counter top. Would not drill it. After several minutes, I checked the blade and found that most diamonds were gone. Would not buy it again.

Cuts porcelain easily
Add a little water and it cuts right through Italian porcelain. It looks like it will last long enough to do 2 full bath renovations - at least.
