While many manufacturers—such as Hilti, Bosch, Milwaukee, Eibenstock, Husqvarna, and AGP—offer a broad range of products, WEKA has consistently focused for decades on the development and production of machines for diamond core drilling and sawing. This focus enables the company to continually develop world-first innovations and make work on construction sites noticeably easier.

All WEKA machines are manufactured in Germany: with a high degree of vertical integration, in-house electronics development, and a focus on durability. This makes them the top choice for specialized companies that rely on reliable, robust, and technically sophisticated solutions. You can find more information about how we work here.

A core drill is a power tool used to drill cylindrical—that is, circular—holes in hard materials such as concrete, masonry, or natural stone. Unlike hammer drills or twist drills, a core drill uses a diamond-tipped drill bit that cleanly cuts through the material. This results in precise holes with only minimal damage to the surrounding area. Because of the diamond-tipped drill bit, the machine is also correctly and fully referred to as a diamond core drill.

Core drills are usually equipped with water cooling or suction cooling.

While a conventional drill typically penetrates the workpiece to a certain depth using a solid-shank drill bit and cuts through the material in the process, a core drill cuts a circle into the material and removes a solid cylinder from the workpiece—known as the drill core. It is specifically designed for drilling in hard building materials and offers high precision and long-term durability, particularly for large diameters or demanding applications.

WEKA diamond core drills are used in the construction and finishing trades, in industry, and in the skilled trades. The goal is to drill clean and precisely circular holes in hard materials. These include, for example, concrete and reinforced concrete, asphalt, stone, and masonry. Typical applications include creating openings for conduits—such as for ventilation, cable harnesses, or pipes—core drilling in concrete or asphalt, and drilling mounting holes during the installation of heavy structural components.

A high-quality core drill must be powerful, robust, and precise, while also being versatile in its application. Other important features include overload protection, ergonomic handling, and a lightweight yet sturdy design. Ideally, a core drill should feature not only a powerful motor but also a multi-speed gearbox for varying rotational speeds and safety sensors. Brushless motors ensure long service life and minimal wear. Specialized accessories ensure a wide range of applications and many areas of use.

WEKA machines are designed for durability and heavy-duty use in professional settings.

Hand-held machines are guided directly by the user. For precise and safe drilling with rig-operated machines, drill stands are used, which are secured either mechanically using dowels, quick-release columns, or anchors, or by vacuum. Drill stands can generally be mounted on walls, floors, and ceilings, provided they offer sufficient stability. The choice of the optimal mounting method depends on the substrate and the drilling situation.

In wet drilling, water is used for cooling to reduce heat buildup and bind dust. This method is ideal for concrete, reinforced concrete (reinforced concrete), granite, natural stone, and tiles. A continuous flow of water over the drill bit cools it. At the same time, the water binds the drill cuttings or dust into slurry, thereby extending the drill bit’s service life.

Dry drilling is performed without water. This is particularly useful for masonry or softer materials such as sand-lime brick, screed, or clay bricks. Respiratory protection is required for dry drilling, as well as a connected vacuum cleaner to extract the drill dust. Dry drilling of concrete (including reinforced concrete) requires the use of machines with soft-hammer technology (for example: DKS15 or DKS32). WEKA offers specialized machines for all applications, which you can find here using our machine search.

WEKA machines are suitable for a wide variety of applications. Depending on the machine and model, they are suitable for core drilling through masonry, concrete, reinforced concrete, natural stone, or asphalt. Details on material compatibility can be found on the respective product pages or obtained directly from our authorized dealers.

For smaller holes in masonry, compact machines with lower power—between 1,000 and 2,000 watts—are sufficient. For concrete or reinforced concrete, more powerful tools with high torque and, if necessary, a water connection are required. For large diameters, voltages of 400 V are also often required. WEKA machines cover a wide range of power ratings for a wide variety of applications. Use our machine search to find the ideal machine for your application.

Hand-guided machines are operated manually and are suitable for smaller diameters or flexible applications. Even when space is limited, access is difficult, or there is little room available, hand-guided core drilling machines offer advantages. With sufficient power, they can even handle drilling through reinforced concrete.

Rig-operated machines are secured to a drilling stand and allow for particularly precise and labor-intensive drilling, such as when working with large diameters, hard materials, or particularly deep holes. Rig-operated core drilling machines are also often a good choice for overhead drilling. Stand-guided core drilling machines not only provide secure guidance but also protect against kickback. Some WEKA machines are suitable for both guidance options.

Which concrete saw is right for a particular application depends on the material being cut. The cutting depth is also a factor, as is whether the sawing will be done using a portable saw or one mounted on a fixed rail.

WEKA offers various types of saws to meet different requirements:

• Hand saws for precise cuts with high maneuverability
• Ring saws for deep cuts with a compact design
• Chainsaws for corners, tight curves, or cutouts
• Cutting saws for standard cuts in concrete or masonry
• Swivel-arm wall saws for precise cuts over long distances

Your authorized dealer will be happy to advise you on which model is right for your project.

Cutting saws use a rotating blade and are typically used for straight cuts in concrete.

Ring saws can achieve significantly greater cutting depths because they do not have a central spindle to which a rotating saw blade would need to be attached. Instead, a saw ring is mounted and secured near the handle.

Chainsaws with diamond-tipped chains are particularly well-suited for tight spaces, small radii, and clean corners. The right saw for your project depends on the material, the environment, and the desired cut.

WEKA’s handheld saws are exceptionally lightweight, compact, and powerful. As handheld concrete saws, they can be used flexibly on construction sites; they require no rail or guide, yet still enable precise work in tight spaces. Thanks to their robust construction, they are ideal for continuous daily use, especially since they offer ergonomic handling.

WEKA saws are designed for professional use with extremely hard materials. Depending on the saw and the accessories used, they reliably cut through:

• Asphalt and rock
• Concrete, including reinforced concrete
• Bricks and masonry
• Natural stone and artificial stone

WEKA sells its machines exclusively through qualified specialty retailers. There, you’ll not only receive expert advice, but in many cases also have the opportunity to test the equipment on-site. Use the dealer locator or send us an inquiry, and we’ll connect you with a contact person near you.

The maximum cutting depth depends on the specific saw model. Ring saws enable particularly deep cuts while maintaining a compact design. The TR40 hand-guided ring saw from WEKA offers a cutting depth of 300 mm. WEKA’s hand-guided cut-off saws and chain saws also achieve impressive cutting depths of 410 and 430 mm, respectively. The combination of machine, saw blade or chain, and intended application is crucial for optimal cutting results. You can find detailed information on cutting depth in the technical specifications for each machine. Click here to view our saws.

A wide selection of accessories is available for WEKA saws. These include, among others:

• Guidance systems for precise cuts
• Adapter plates and quick-change systems
• Water connections and suction devices
• Luggage and transportation solutions
• Genuine accessories for installation and maintenance

Your local dealer will help you choose the right accessories for your machine and your specific application.

All WEKA saws feature a built-in water connection. The water is directed directly onto the saw blade or saw chain. This constantly reduces the frictional heat generated by the saw blade or chain, and the dust released is immediately bound by the water, keeping the air clean. The targeted cooling provided by the water during the cut also reduces wear.

Depending on the model, you can connect the water supply to external systems or feed it directly from a water tank. In some cases, the water flow can be regulated via a valve. Please refer to the information in the respective operating instructions.

WEKA saws are designed for a long service life and high durability. Nevertheless, you should have the following items checked regularly:

• Condition of the cutting disc or chain
• Water supply and connections
• Cleaning the machine after use
• Visual inspection of wear parts

For repairs or maintenance, we recommend our certified WEKA service workshops. There, your machine will be professionally inspected, repaired, and serviced with genuine parts.

The noise level of WEKA saws during operation depends on the model, the material being cut, and the work environment. You can find the exact sound power and sound pressure levels in the technical specifications for each machine. When working with concrete saws, we always recommend wearing appropriate hearing protection to safeguard your health.

Your safety is our top priority. When you purchase from a specialty retailer, you can receive instruction on safe handling upon request. In addition, WEKA offers comprehensive operating instructions and documentation. For specific applications or questions, please contact your specialist retailer or our technical support team.
