What Materials Can I Use My Diamond Drill Bits On?
Diamond drill bits are perfect for drilling holes through hard materials such as these:
*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 in precious stone we recommend using the small diamond drill bits which have a solid, flat end, or tip. Do not use diamond drill bits on metal, soft wood, plaster or soft plastic. These materials are too soft and will cause the diamonds on your drill bit to clog up. When drilling holes in soft metals, plastics 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.
What Is A Diamond Core Drill?
As with all diamond drill bits you should use water as a lubricant and coolant. Being hollow, allows the water to flow up inside and around the inner core of these drill bits as you are drilling, helping to keep the drill bit cool and removing the debris. These are the best drill bits for rock.
Diamond core drills are available in sizes 1mm - 3mm and 3.5mm - 60mm and larger.
They also come in a range with a 2.35mm shank
As you drill, the water swirls around inside the core. This helps prolong the life of your drill bit and helps to prevent any cracking or shattering of the material you're drilling.
