Diamond Drill Bit FAQs
What is a diamond drill bit?
A diamond drill bit is any one of a variety of tools used with drills, rotary tools, and routers that has tiny particles of industrial diamond embedded into the material of the bit, which is usually made of a very hard type of like carbide steel.
What is a diamond drill bit used for?
Diamond drill bits are perfect for drilling holes through hard materials, including:
- Glass, sea glass, beach glass, fused glass, sheet glass
- Stone, gemstones, rock, pebbles, minerals
- Ceramic, porcelain, tiles, glazed pottery, plates, china
- Shell, antler, bone, fossil
- Very hardwoods
- For very small precision holes for jewelry-making purposes and precision holes in all glass, precious stone, or porcelain tile, it is recommended to use small diamond drill bits which have a solid, flat end or tip. These are available in sizes as small as 0.75mm – 3mm.
- When renovating your kitchen or bathroom walls fastening mirrors in the bathroom, or installing a shower, you will need to drill holes on mirrors or tiles without cracking them; hence you will need to use these diamond drill bits to make those holes very precise.
- Some models utilize vacuum brazed technology, so the bit can be used at a higher temperature cutting harder materials, great for drilling clean holes to granite, ceramic, glass stone, brick marble tile stone Jars, and similar materials.
What materials are not suitable to use a diamond drill bit?
Do not use diamond drill bits on metal, softwood, plaster, or soft plastic. These materials are too soft and will cause the diamonds on your drill bit to clog up.
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 difference is between small diamond drill bits and small diamond core drills?
Small Diamond Drill Bits have a solid end and therefore a larger surface area, so they last longer than the small diamond core drills but may take longer to drill a hole. They are more robust and ideal for very tough, dense pieces of sea glass, hard stone, precious stone, gemstones, hard shell, bone, and antler.
Small Diamond Core Drills will drill a hole quicker than the small diamond drill bits but will not last as long because they have a smaller surface area.
How long does a diamond drill bit last?
Your diamond tip drill bits lifetime will depend on many factors: speed, lubricant, pressure, and the density of the material you’re using. If you’re drilling through sea glass, for instance, these maybe thousands of years old, and we don’t know the source of the glass. That said, some have achieved more than 250 holes in sea glass from just one bit.
Is it safe to use water near your drill?
Water can either be fed onto your material via a pump, a running tap, a drip-feed, or you can immerse your material in the water, ensuring about 1cm covers the material you will drill.
If you’re drilling a tile on the wall, you can squeeze the water onto the tile with a sponge. If you’re shooting large pieces of glass or stone, you can create a putty ring that will act as a well for your water.
Why choose diamond drills/bits?
Diamond Drills/Bits will drill materials faster, produce smoothes surface finish quality, provide consistent performance, and yield (cost per part) possible. Diamond drills are an excellent alternative to carbide and other types of drills, unlike carbide, high-speed steel, & other types of drills.
What is an electroplated diamond drill bit?
Most Electroplated diamond drills/bits have only one layer of diamond coated on a steel body. Diamonds stay only on the surface. When this diamond portion is worn out or peeled off, the diamond drill will slow down, drill on the side (not drill straight) or stop working (drilling) altogether.
Can you use a diamond drill bit on super hard tile?
Using a diamond drill bit is the only reasonable option when drilling in the newer super-hard tile. However, even with a diamond drill bit, the extremely hard material is not very forgiving if inappropriate drilling techniques are used. Good drilling techniques must be used.
What kind of drill bits do you use for cutting?
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.
What is the difference between sintered and electroplated or coated diamond drill bits and burrs?
- Electroplated or coated diamonds are bonded to the drill bit using nickel in a single layer, and although they won’t last as long as sintered, they are a cheaper alternative.
- Sintered diamond drill bits – the diamond grit has been bonded to the matrix at very high temperatures. Therefore, it has several layers of diamonds. By dressing or cleaning with an aluminum oxide stone, it will help maintain the life of your drill bit or burr, revealing a new layer of diamonds each time.
- Electroplated, or coated diamond drill bits as they’re more commonly referred to, tell us that the diamonds are coated onto the steel shank in a single layer; therefore, once this layer has worn away, the drill bit will need to be replaced. These are the most economical and popular types of drill bits.
- Sintered diamond core drills and Sintered burrs have several layers of diamonds and therefore last a very long time but will also be more expensive than coated diamond drill bits.
- Sintered diamond bits require cleaning or dressing before and after each use with an aluminum oxide stone, thus revealing a fresh layer of diamonds each time.
- Sintered core drills are popular with stonemasons, sintered burs with sculptors, glass engravers, and stone carvers.

General Tips
- A high-speed tool works best; speed is important, not pressure.
- Cooling is important. Keep the hole you’re cutting constantly bathed in water. You can feed water to the drilling spot, always keeping it wet. Or you can submerge the whole piece in water in a plastic container.
- Use minimum pressure on the drill, just enough to let the diamond abrasive grind away the material. Using extra pressure will just damage the drill bit and not get you there any sooner.
- The shank must be installed tightened, and the grinder speed should not be too high.
