DiamondSure Drill Bits

DiamondSure bonded diamond core drill bits cut through materials where other bits fail. They are designed to drill in the hardest surfaces or the most delicate and fragile.

• Wet diamond drill bits for hard porcelain & glass tile.
• Use with adjustable hole saw guide.
• We tested this bit in hard porcelain and the result speaks for themselves!
• Drop water on area where hole is made.
• Start drilling hole applying very little pressure.
  Do not push straight down
• Make sure water is sufficient to wet bit.
• DiamondSure bits can be used in any standard variable speed drill.
• They are electroplated, blonded and designed for drilling to depths of about 1/2″ in ceramic tile, porcelain tile, glass block, slate, marble, quartz, granite, limestone and more.
• Not designed for use on concrete, masonry, metal or for use with impact hammer drills.
• Core drill bits have a hollow center and cut a circle in the material to create a hole.
• The life of any type of diamond drill bit depends upon the hardness, abrasiveness and thickness of the material being drilled and the specific drilling techniques used (drill speed, pressure and lubrication), the diamonds of a drill bit don’t actually wear out as much as they wear off due to heat and friction caused by the extreme hardness and abrasiveness of the material drilled.
• Drilling in glass, ceramic, marble, is a slow process compared to softer materials like wood or even metal. A deep hole can be drilled in wood in just a few seconds, while it can take more than 20 or 30 seconds to drill a hole in standard 1/8″ thick glass. In some very hard stones and tiles, it may take 2 to 3 minutes to drill only 1/4″ deep. Using diamond bits to drill in hard materials is not difficult, however, it takes time. A person should consider that they aren’t ‘drilling’ a hole, as much as ‘grinding’ a hole.
• All core drills have shaft sizes of 3/8″ or less, for use in standard drills.
