How to Harness the Power of Diamond Drill Bits in Diamond Drilling?

Diamonds are one of the hardest materials in nature. It’s properties state to have strong carbon to carbon covalent bonds. Diamonds are considered as valuable in various industries, such as the gems and jewellery industry. However, the fact is the global supply of natural diamonds is employed for industrial purposes and only about a quarter of all diamonds are used in fine jewellery. Nonetheless, the hardness of this element is effective for instruments in the other industries too, especially diamond drilling in construction and manufacturing. Let us take an example in Diamond Drill Bits which are considered as a heart of diamond drilling process. Diamond drill bits are a very efficient tool to pierce and make holes through hard non-wood materials. Used on hardwood materials too but on a few occasions.

Information you Must Know About Diamond Drill Bits When it Comes to Diamond Drilling

The 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. With regard to its use as an abrasive or use in semiconductors, diamond is invaluable because of its thermal stability.

Some diamond drill bits require water or another coolant to lubricate the bit as it makes its way through tough (hard and challenging) materials. Choosing the right Diamond Drills / Bits for your drilling project/requirement is the secret to achieving the perfect diamond drilling result. In addition, if you use the Right Diamond Drill, it will help you save both costs as well as time. Also, it will avoid an unnecessary trial & error process.

These are the points to ponder when you use diamond drill bits for diamond drilling.

Keep it slow

While drilling any material, it is advisable that you keep the process slow and steady. This will hamper you from damaging other parts of the material and drill the hole with utmost accuracy and without any cracks formation. It even increases the durability of the drill bit.

Help cut through various types of hard materials
Diamond drill bits can drill a hole through materials like stone, gemstone, glass, sea glass, ceramic, porcelain and more. It is even useful for shell, bone, pebbles, fused glasses, tiles or very hardwood.

Available in many sizes

They are available in smallest as 0.75 mm in size. Which is very effective while making jewellery where minute changes are required. It can drill holes through soft metal and plastics where precision necessary with the substance fragility. These drill bits are even available in 60 mm or more in size.

Diamond drill bits are hollow

Lubricants such as oil can be used as drill bits are hollow. Though it has been observed that water is a better & cost-friendly lubricant. You can even clean the debris through the hollow area. It even allows water to flow inside and around the core area while you are drilling. That works as a coolant as well.

Diamonds can come off

Speed drilling and high pressure applied while drilling must be avoided. It affects the characteristics of diamond drill bits. Ideally, the drill speed is kept slow consistently. If ever the diamonds fall away, the pressure applied to it is too high. Harder your material slower the drilling speed should be.

Never use it for tempered glass

Tempered glass is very brittle in nature. Even at the tiniest size of drill bit used to make a hole won’t be useful. Instead, it ends up with a cracked glass ruining the material. Diamond drill bits are not useful for tempered glass.

Diamond twist drill bits used for hole enlargement

This tool is effective in enlarging a hole. It is usually not practiced to form a hole with its twist characteristic. The drilling instrument is not straight with diamonds but curved. This way it can ruin the closer areas around the hole while creating one. It is beneficial to increase hole size in pearls. The size range is from 0.5 mm to 3 mm.

Signing Off

Diamond Drilling is now a trend, and it is here to stay for longer. However, never ever use diamond drill bits on metal, softwood, plaster or soft plastic. These materials are too soft and tender; and, diamond core drilling on these will cause the diamonds on your drill bit to clog up.

In case, you’re a regular user of diamond drill bits, in your toolbox, it is worth having a combination of both small diamond core drills and small diamond drill bits. This is because sometimes you don’t know the extent of “tough” until you start drilling!

FAQ for Diamond Drilling

In what all cases, I can use diamond drill bits?

A diamond drill bit is a helpful tool when it comes to making holes in hard non-wood surfaces such as ceramic, porcelain, glass, sea glass, stone, shell, antler, bone, fossil, marble and granite.

Can I use diamond drill bits on plastic?

No, it isnt advisable to use diamond drill bits on too soft materials like metal, soft wood, plaster or soft plastic.

Small Diamond Core Drills or Small Diamond Drill Bits - Which should I use?

For items like or very tough, dense pieces of sea glass, very hard stone, precious stone, gemstones, hard shell, bone and antler, use small diamond drill bits. Whereas, for items like glass, sea glass, pebbles, stone, slate, ceramic, plates and shell, use small diamond core drills.
