The best selection of lapiary,glass,stone, masonry & concrete core bits - These diamond core drill bits are still our most popular tools for drilling through hard materials. Sometimes referred to as diamond hole saws,We offer a variety of Diamond Core Drill Bits or Diamond Hole Saws for your needs.Diamond drill bits are perfect for drilling holes through Glass, sea glass, beach glass, fused glass Stone, gemstones, rock, pebbles Ceramic, porcelain, tiles, glazed pottery, plates Shell, antler, bone, fossil, very hard wood.

For jewellery making purposes and precision holes we recommend using the small diamond drill bits which have a solid, flat end, or tip, as mentioned above. These are available in sizes as small as 0.75mm. For drilling holes in plates, fused glass and dense, hard sea glass we recommend using a small diamond core drill. These are available in sizes from as small as 1mm.

DO NOT use diamond drill bits on metal or soft wood. These materials are too soft and will cause the diamonds on your drill bit to clog up. When drilling holes in soft metals and wood use High Speed Steel drill bits (HSS) and for drilling holes in hard metals use Carbide Drill Bits Diamond is the hardest material and therefore, anything else can be cut or drilled with it. If you are cutting or drilling through very hard materials such as Sapphire then bear in mind you will need a lot of patience and perhaps more drill bits than you would if you were drilling a hole through glass or Opal.
