If you need to make large and precise holes in materials such as bricks, blocks, tiles or concrete, you need the best core drill and the best core drill bits for the job. Core drilling is a cutting technique that uses a hollow cylinder with sharp teeth to cut through the material and leave a cylindrical core behind. Core drilling is widely used in construction, mining, and other industries that require accurate and smooth holes for pipes, cables, or other purposes.
But how do you choose the best core drill and the best core drill bits for your project? There are many factors to consider, such as the type, size, and hardness of the material, the frequency and duration of the drilling, the budget, and the working environment. In this article, we will explain the main differences between the two types of core drill bits: carbide and diamond, and how to select the best core drill for concrete and other materials.
Carbide core drill bits
Carbide core drill bits are the cheapest option for core drilling. They are made of metal, usually tungsten carbide, and have teeth around the circumference that cut the material. Carbide core drill bits are suitable for soft to medium-hard materials, such as bricks, blocks, stucco, or tiles. They are not recommended for very hard materials, such as concrete, granite, or fiberglass, as they will wear out quickly and produce rough cuts.
However, carbide core drill bits require dry cutting, which means that you need to stop frequently and use coolant to prevent the bit from overheating and burning. You also need to sharpen the teeth regularly to maintain the cutting performance. Carbide core drill bits are a good choice if you do not need to drill very often or very deep, and if you are on a tight budget.
diamond core drill bits
Diamond core drill bits are the best option for core drilling. They are made of steel and have diamond segments around the circumference that grind the material. Diamond core drill bits are suitable for hard and abrasive materials, such as concrete, granite, or fiberglass. They are also ideal for smooth and accurate cuts, as they produce less vibration and noise than carbide core drill bits.
They require wet or dry cutting, depending on the subtype. Wet cutting uses water to cool and lubricate the bit, while dry cutting uses air. Wet cutting allows you to drill longer and deeper without stopping, while dry cutting is more convenient and less messy. Diamond core drill bits are a better investment if you need to drill frequently or deeply, and if you want the best quality and durability.
How to choose the best core drill for core drilling
The best core drill for core drilling depends on the type of core drill bits you use and the power and speed you need. Generally, you need a higher power and speed for harder and thicker materials, and a lower power and speed for softer and thinner materials. You also need to consider the size and weight of the core drill, the safety features, and the accessories.

The selection of a core bit has to be spot-on to ensure that none of your resources are wasted and are used to the best of their ability. This selection is usually based on the size and depth of any hole that is required as well as the hardness of the rock formation that is going to be drilled, the capacity of the rig that is being used, and the skill that the drilling professional possesses.
This information about three of the main drill bits that are used in exploration core drilling will help you make the right decision:
Impregnated Diamond Core Bits
Impregnated diamond core bits are generally used for exploration core drilling through hard and extremely hard rock formations. These bits can be used for drilling through almost all types of formations apart from clay, chalk, and a small number of other unconsolidated formations. Impregnated diamond core bits are not as sensitive as other types when it comes to rough handling, incorrect use, or abuse.
Surface Set Diamond Bits
Surface set diamond bits are designed more for drilling through formations that are graded between the soft and medium-hard rock. When compared to impregnated diamond core bits, these have a higher rate of penetration and can be used with lower-powered drills. However, due to only having one layer of synthetic diamonds, the bits will generally have a shorter drill life.
Poly-Crystalline Diamond Composite Bits (PDC)
PDC bits are suitable for drilling through medium to hard rock formations such as salt, limestone, and clay. The benefits of using a PDC are that they are extremely fast at drilling, are more durable and have a longer life than surface set bits, and can drill a lot faster than other types of drill bits.
Rockpecker is the most trusted PDC bit manufacturer in the region. Learn more about the drill bits and accessories we offer by visiting www.rockpecker.com.

When it comes to drilling through hard materials like tile, stone, or porcelain, having the right tools is essential. Diamond drill bits offer exceptional performance and precision in these demanding tasks. In this comprehensive buying guide, we will delve into everything you need to know about diamond drill bits. Whether you're a construction professional or a DIY enthusiast, understanding the features and considerations of diamond drill bits will help you make informed purchasing decisions. So, let's explore the fascinating world of diamond drill bits together!
Diamond drill bits are designed with a unique composition that sets them apart from conventional drill bits. They feature a diamond-encrusted tip that provides remarkable hardness and durability. The diamond coating enables smooth and precise drilling, allowing you to achieve clean holes without causing damage to the surrounding material. These drill bits are perfect for creating holes in materials like tile, stone, or porcelain, where standard drill bits may struggle to deliver the same level of accuracy and efficiency.

Diamond drill bits come in various sizes to accommodate different hole diameters. Ensure that you select a drill bit size that matches the diameter you require for your specific project. Additionally, check the compatibility of the drill bit with the material you'll be drilling. Different drill bits are designed for specific materials, such as tile, stone, or porcelain.
Diamond drill bits can be used for both wet and dry drilling. Wet drilling involves using water as a lubricant to cool down the drill bit and flush away debris, resulting in smoother and more efficient drilling. Dry drilling, on the other hand, is suitable for smaller projects and can be done without the need for water. Consider the requirements of your project and choose the appropriate drilling method.
The speed and rotation of the drill play a crucial role in the performance of diamond drill bits. Optimal speed and rotation will ensure effective drilling without causing excessive heat buildup or damaging the drill bit. Follow the manufacturer's recommendations regarding the suitable speed and rotation for the specific diamond drill bit you're using.
If you are using a drill press or bench press, you won't be able to angle the drill. Instead, secure your material in place with a vice. However, if you are using a hand-held drill like a Dremel, flex shaft, pendant drill, cordless drill, or handheld rotary tool, continue reading.
To prevent the drill bit from skittering across the surface, angle your drill when starting the hole. Once the initial hole is made, you can drill vertically. This technique is particularly useful when drilling through smooth materials like glass or stone pebbles.
Another option is to use a small piece of masking tape on the starting point. This prevents the drill bit from sliding around, which is especially handy when drilling through tile or glass bottles. However, this method is more effective with larger drill bits, typically ¼” and above, rather than smaller ones.
For drilling holes in glass, stone, or ceramic, consider using high-quality tools like the Milwaukee Diamond Plus Hole Saws or the Milwaukee Diamond Max Hole Saw 3-Piece Set, available in our collection of drill bits for tile and stone
Diamond twist drills excel at enlarging holes rather than creating them. They are highly popular among bead artists for increasing hole sizes in beads and are ideal for pearls as well. Sizes range from 1/64” to ⅛” m.
Tip: Diamond twist drills can also be useful for preventing condensation build-up in double-glazed windows. By making a hole in the inside bottom corner window and the outside top corner window with a ⅛” twist drill, you can follow a suitable tutorial to address the issue of misted-up windows.
While there are videos showcasing the use of ball burrs to drill holes, it's important to note that diamond ball burrs are primarily intended for shaping, engraving, carving, and grinding, however they are not designed for drilling holes and are not as effective as the small diamond drill bits.
Shovel-shaped, spade-shaped, and pointed drill bits are also available for drilling holes in hard materials. However, based on our extensive experience, we have found that these options do not perform as well as desired.
Q: Can I use a diamond drill bit on glass?
A: Yes, diamond drill bits are suitable for drilling through glass. However, it's crucial to use a slow speed and apply gentle pressure to avoid cracking or chipping the glass. Additionally, using a lubricant like water during the drilling process can help reduce heat and ensure smoother drilling.
Q: How long do diamond drill bits last?
A: The lifespan of a diamond drill bit depends on various factors, such as the quality of the bit, the hardness of the material being drilled, and the drilling technique employed. With proper care and usage, diamond drill bits can last for a significant number of drilling hours, providing reliable and precise performance.
Q: Can diamond drill bits be used on metal surfaces?
A: Diamond drill bits are not designed for drilling through metal surfaces. They are specifically engineered for hard materials like tile, stone, or porcelain. For drilling through metal, it's recommended to use drill bits specifically designed for metal drilling to achieve the best results.
Q: What are some recommended diamond drill bits for drilling through tough materials like tile and stone?
A: For exceptional performance in drilling through challenging surfaces, we highly recommend the Milwaukee Diamond Plus Hole Saws. These hole saws are specifically designed to tackle the rigors of tile and stone drilling, delivering precise and clean results.
