8 Facts you Need to Know About Diamond Core Drill Bit

You can use the diamond core drill bit to punch holes in other devices and holes with different diameters. Besides ordinary concrete, diamond drill bits can also quickly cut out reinforced concrete, brickwork frames, steel bars and other hard structures.

This technology is not only more effective than other traditional technologies but also the most cost-effective method for drilling hard structures and digging the ground. This article introduces eight facts about Galvanized Steel Wireto help you better understand the diamond core drill bit.

1.Usage Of The Diamond Core Drill Bit

Diamond core bits are cutting tools that remove materials and make holes, usually in a circular, cross-section. A diamond drill is unique because you can use it in making smooth and neat holes in non-wooden surfaces.

In case the name misleads you to think it is a diamond tool, diamond core bits are not diamond tools. Instead, their parts contain diamond powder. Since diamond is one of the hardest substances to break in the world, you can be sure of where this tool derives its name. It implies that it is powerful and can boreholes in the almost impossible materials around.

Depending on the diamond core drill that you use, you can use it to drill holes in: 

• Tough, non-ferrous materials such as fibreglass, ceramics, limestone, porcelain, granite, marble, glass block, quartz, stone tiles, slate, etc.

• Hard substances such as precious gems, bone, hard shells, etc.

In most cases, you can use diamond core drills to perform the following tasks:

• Fix toilet bolt anchors, heating and plumbing pipe holes, floor-mounted fixtures such as floor lights, bathroom tub, water closet, etc.

• Fix towel bars, handrails, showerhead holes, curtain rods, stall dividers, soap dispensers, electrical outlets, doors, etc.

• Drill holes in porcelain tiles, glass drilling for lights, pottery drilling for lamps, china pottery drilling for clocks, etc.

Under no condition should you use electroplated diamond core drill bits to drill holes in hard metals, masonry products, concrete, concrete products, porcelain-cast iron fixtures, hard stones over 1/2″ deep amongst others?

2.The Material Form Of The Diamond Core Drill Bit

There are two critical types of drill bits: electroplated drill bits and sintered diamond drill bits.

• Electroplated diamond drill bit: 

This drill has only one layer of diamond coating on a steel body. You can use this diamond core drill bit to drill holes in softer materials within 1-6 on the Mohs scale of hardness. It implies that anything higher than six can cause drill life to reduce.

By using electroplated drill bits on softer and more ductile materials, you will have brilliant results with faster drilling action, minimum heat dissipation and smooth surface finish.

This drill is favourite in the glass and composite industries where its use is not rigorous. It is suitable for occasional use. For instance, you can use it to drill a few holes when installing marble, tile, glass mirrors, etc. in your homes.

For optimal results, it is advisable to use electroplated drills to make holes in materials that are less than 1/4″ thick. It will prevent the practice from wearing out within a short time.

Electroplated exercises are convenient to use for beginners and hobbyists. Ensure to avoid using it on hard surfaces such as concrete or concrete products, porcelain-cast iron fixtures, and hard stones over 1/2″ deep, etc.

• Sintered diamond drill bit:

This drill has multiple layers of diamond on the steel shank. It means that unlike the electroplated exercise that has only one diamond layer which peels off after a short period, sintered drills will last for a more extended period.

Before and after using sintered practices, it is important to clean with aluminium oxide rock to expose a fresh diamond coat. It gives you the best performance per hole and optimal results.

Although the price of sintered drills is higher than that of electroplated exercises, We should note that the performance of sintered drills is about 20 times that of electroplated diamond drills. Not only will you save money, but you will also save energy and time by using one training to make several holes.

When you peel the coating of the sintered diamond drill, you will get another surface with even layer for smooth results and performance. The drilling speed is consistent, and the exercises wear evenly, leaving no room for tarnish or uneven drilling results.

3.Diamond Core Drill Bit General Service Life

Before you buy your diamond core drill, the essential feature to look out for is its life span. Your customers getting the best service life for their diamond core drill is essential as it determines the profit you will make as a dealer or wholesaler. We have to extend the life of the diamond drill, need to consider some critical issues:

• Pick the right diamond drill bit for the hardness of material: 

When choosing the diamond core drill bit, it is essential to choose the one that fits the hardness of the material you want to drill in. The Mohs hardness scale ranges from 1 to 10. Choosing the one that suits your needs will prolong the service life of the diamond drill.

• Ensure proper flow of water: 

Ensure there is a constant flow of water to the bit. Do a routine check of the rods to ensure that they do not leak. If the pressure flows appropriately, the drills will be cool.

• Proper lubrication is critical: 

Reduction in friction will ensure that the diamond drill lasts longer. Use an environmentally safe lubricant to reduce wear and tear. It will keep the core bit cool and prevent the rods from rust.

4.The Diamond Core Bit Size Selection

Choosing the right core bit size is one of the essential choices you must make when buying a diamond drill. You must consider some factors:

• The hardness of the material you want to drill in: Your choice of diamond drill depends on the hardness of the material you want to drill in. The harder the material, the bigger the size and vice versa.

• Budget: Your choice of drill bit size relies on the project that you want to do, and the cost it will incur.

• Speed: For better performance and top speed, it is necessary to choose the drill bit size that suits your needs.

5.What If The Debris Gets Stuck In The Hole?

While drilling, you might encounter some minor challenges such as debris getting inside the core. You can get rid of this by drilling your next piece of material as this dislodges the debris from the centre, and you can continue your smooth work. It implies that you should continuously drill into the fabric.

In case the debris doesn’t dislodge after trying the first step, use a wire brush to remove the debris.

6.Can You Use It For Tempered Glass Work?

It is highly inadvisable to use a diamond core drill bit to make drills in the tempered glass as the probability of breakage is as high as 80 or 90 per cent. The manufacturing process of tempered glass causes a sizeable amount of stress, and this stress causes cracks when drilling occurs. Since you don’t know the pressure the tempered glass is under, drilling holes is unadvisable.

7. Speed Control Of Diamond Core Bit

The drill speed of a diamond drill differs from one manufacturer and model to another. Electroplated diamond drills allow for slow speed as the hardness of the material increase. It is an attempt to preserve the lifespan of the tool.

Also, higher rates result in a quicker burn of the diamond bits, which can lead to money and time wastage. By controlling the speed of the diamond drill to suit the material you are drilling in, you will increase the drill bit life.

You must also consider the lubrication and drill pressure when determining the drill speed. When the drill speed is too fast, the diamond drill will feel warm to touch after use. Extreme heat can cause material breakage.

8.The Main Advantages Of The Diamond Core Drill Bit

Some core advantages of diamond core drill bit include:

• Low noise: In contrast to concrete core bits, diamond drilling technology is ideal for ensuring high-quality work without noise.

• Produces less dust: Diamond drilling is the cleanest and most environmentally friendly drilling technology.

• size and shape: You can easily find the size that fits your project to get neat, smooth and exquisite work results.

• Fast and effective: It saves time, energy and cost.

• You can control it remotely: Mechanized equipment can ensure the safety of workers.

• You can use it for multiple purposes: Depending on the work you want to do, you can use diamond drills for glass, granite, in optical industries, for underwater activities, to fix things at home, etc.
