A diamond tip drill bit is used to drill holes through heavy-duty or delicate materials like glass, stone, ceramic, and bone. Diamond drill bits are constructed with a metal structure with diamonds embedded into the metal. These drill bits are used to drill precision holes for projects, jewelry, and any hard material.
Are diamond bits actually diamond?
Diamond drill bits get their extra cutting power from little pieces of diamond powder embedded in them. These drill bits, whether twisted or cylindrical, are particularly useful in bathroom applications where you have to drill through tiles to mount towel racks and vanities.
Are diamond drill bits any good?
They are the best drill bits for rock, DIY or craft projects and for the professional tradesman. Diamond drills for tiles is a must and will drill holes far easier and with a smoother cut than any other tile drill bits.
Can diamond bits be used on wood?
Bonded Diamond Drill Bits are used on glass, stained glass, ceramics, ceramic tile, porcelain, porcelain tile, limestone, marble, granite, slate, stone and fiberglass. Drills used on wood or metal have a sharp metal tip or teeth, that cut into the material. These types of drills do not work on glass, marble, etc.
How long does a diamond bit last?
Varying with application, an average electroplated diamond core drill/bit will last you 80 to 120 holes. Whereas a conventional metal bond (sintered) diamond drill should last you about 1,200 holes. And a diamond drill with SMART CUT™ technology will last more than 2,000 holes.

Why are drill bits often topped with diamonds?
Why Diamonds? The chemical composition of diamond makes it the hardest material, natural or man-made, known to man. … An additional advantage of using diamonds in drilling tools is that the life of a diamond drill bit is much longer than any other drill bit material.
Why is diamond used for tips of drills?
Heavy-duty drill bits – such as those used in the oil exploration industry to drill through rocks – are made with diamonds so that they stay sharp for longer. Diamond is insoluble in water. It does not conduct electricity.
Can diamond drill cut through steel?
Diamond Drill Bits
The use of diamond, the hardest material known to man, makes these drill bits extremely suitable for drilling through steel. Diamond drill bits are more expensive than standard drill bits because the manufacturers use such a precious material , and for their unique ability to cut into steel.
Why is diamond so hard?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
Can you use metal drill bits for wood?
While wood drill bits are too soft to drill through metal, metal drill bits can be used on any surface. However, if you’re using a metal drill bit on wood, you’ll have to reduce the pressure to prevent damaging the wood.
Can HSS drill bits be used for wood?
High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum. Cobalt drill bits are extremely hard and dissipate heat quickly. They’re mostly used for boring in aluminum and tough metals such as stainless steel.
Are diamond drill bits expensive?
Sintered diamond bits are more expensive and because they are heavy duty, they drill more slowly, but they last longer. Depending upon the material being drilled and the drilling techniques used, Sintered diamond bits can last 30 to 50 times longer than a bonded diamond bit, sometimes even longer.
How are diamond tipped drill bits made?
PCD has good fracture toughness and good thermal stability, and is used in making geological drill bits. Polycrystalline Diamond Composite or Compacts (PDC): They are made by combining some layers of polycrystalline diamonds (PCD) with a layer of cemented carbide liner at high temperature and high pressure.
