Core drills 50

Whenever there is a need to drill holes in various types of hard natural or artificial stone, there is no better помощник than professional diamond core bits. For such tasks, it is also worth using a diamond core drill bit or diamond hole saws, which ensure cutting precision and long tool life. Among diamond tools, you can easily find a hole drill bit for drilling in the most popular types of materials:

• Tile hole saw
• Concrete core bits
• Porcelain stoneware hole saw

Core bits for different types of materials

For professionals, we also recommend a 125mm hole saw and a porcelain stoneware hole saw set so that you have all the necessary diameters in one kit.

There are many different types of diamond core drill bits, so it is important to correctly select the core bit, the device, and the type of drilling (with or without cooling) depending on the task being performed.

Do not forget also about a reinforced concrete hole saw and wet porcelain stoneware hole saws when greater precision or drilling in hard materials is required.

Diamond core drill bits for concrete

For drilling in concrete and reinforced concrete, both dry and wet drilling are used. Professionals often choose a concrete core drill bit to maximize the tool’s capabilities. Diamond core bits intended for dry and wet drilling differ in composition, so it is important to use the drill bits according to the manufacturer's recommendations.

All diamond core bits are segmented and, depending on the diameter, may have from several to several dozen segments. For large diameters, diamond core bits are useful because they allow segment regeneration and cost savings. Such diamond drill bits can be refurbished after the complete wear of the segments. Thanks to this, new segments can be applied to the drill body, and in this way you can significantly save on purchasing a new diamond tool.

Dry drilling is used for making holes in concrete with a diameter not greater than 100-120 mm. This results from the fact that the operator’s force may not be enough to drill through very hard or reinforced concrete. For such work, core drill bits as well as a diamond core bit are used for maximum precision. To make larger holes, core drilling machines with a stand and water supply are needed. In some cases, specialists use dry drilling for holes above 120 mm, but only when they have a stable stand for mounting the drilling machine.

Wet drilling is used for processing hard and reinforced concrete with diameters from 42 mm to 500 mm. The advantages of wet drilling include the ability to make large and deep holes, as well as high processing speed even in very hard concrete with a large amount of metal (of course, when using a professional diamond core drill bit for wet drilling). Wet drilling is usually carried out using a special stand mounted near the location of the planned hole. In this case, a diamond hole saw for porcelain stoneware is also useful if you need to drill in hard finishing materials.

Diamond hole saw for tiles

Drilling in tiles is much simpler because the depth and diameter of the holes are smaller here than in concrete. Most often, the tile thickness is about 10 mm, and the maximum diameter of holes made in the tile is 130-150 mm. However, drilling in ceramics and porcelain stoneware requires greater precision because it is most often finishing work, and in the end we want to obtain an even hole without chipping. For this purpose, diamond core bits work best, allowing clean and precise cutting even in hard materials. For such applications, porcelain stoneware core bits, a diamond drill bit, or a core drill bit are ideal, ensuring clean holes without chipping.

Both solid and segmented hole saws are available for tile drilling. Segmented tile core bits are intended exclusively for dry work, while solid ones can be used for both wet and dry drilling. For such tasks, a core drill bit will work perfectly, ensuring clean and precise holes without the risk of damaging the material. Professionals also use a hole saw for porcelain tiles and a porcelain stoneware hole saw to be able to drill different diameters.

A diamond hole saw for dry drilling of tiles is used on angle grinders. Working with an angle grinder involves high RPM, which is why dry drilling is much faster than wet drilling. Additionally, wet porcelain stoneware hole saws are recommended for more demanding applications. Diamond core drill bits for dry tile processing are made using larger diamonds, which unfortunately increases the probability of chipping. Such drill bits are used to create holes that will later be covered (e.g. for electrical sockets).

Diamond hole saws for work with water cooling operate much more slowly (because they are used with lower-speed tools and finer diamond grit), but in return they practically do not cause chipping on the tile edges.

Factors affecting the durability of diamond core bits

The service life of a diamond tool is very important for every specialist. What parameters affect the operating life of a diamond core drill bit?

• Hardness and abrasiveness of the material
• Power and RPM of the device
• Type of drilling (wet or dry)
• Correct matching of the core bit to the material

The correct selection of the segment type for drilling in concrete is especially important:

• RS segment – soft segment for processing hard concrete
• RM segment – medium hardness, universal application
• RH segment – hard segment, excellent for highly abrasive materials

Before you buy just any hole saw, it is better to carefully familiarize yourself with the properties of the material you intend to process. It is also good to have a reinforced concrete hole saw and an 8mm drill bit for porcelain stoneware at hand for more precise tasks.

Tile core bits are more universal and are suitable for processing both soft ceramic tiles and hard porcelain stoneware.

Diamond hole saw: work tips

Proper use of core drill bits will help extend the service life of your equipment and the drill bit itself, as well as complete the work faster and more accurately.

• Follow the proper method of cooling the drill bit
• Start drilling with the help of a template to avoid the drill bit slipping
• Do not allow the segments to overheat
• During manual drilling, gently rock the drill bit from side to side to make the work easier
• When drilling with water cooling, do not spare water in the drilling zone
• After finishing drilling, remove the drilled material from inside the core bit before you start drilling a new hole
