In professional tiling and general trade work, precise drilling is a key factor in the success of your projects. Drill stands, stone drill bits, and tile drill bits provide the perfect combination of accuracy, safety, and efficiency—specifically designed to meet the demands of tough materials such as natural stone, porcelain tiles, and ceramics. At the Karl Dahm online shop, you will find high-quality products that simplify your daily work and guarantee excellent results.
A drill stand is an indispensable tool for exact drilling. It securely holds your drill in place and guides it precisely, allowing you to achieve straight, uniform holes—even in hard-to-reach or awkward locations.
Typical problems such as the drill slipping or drilling at an angle become a thing of the past. A sturdy drill stand also significantly reduces the risk of injury and improves workplace safety.
At Karl Dahm, we offer various models like the KDB-200 Drill Stand (Art. No. 40 103), the KDB Drill Stand (Art. No. 40 107), and the KDB-201 Large Format Drill Stand (Art. No. 40 104). These are characterised by robust construction, ease of use, and integrated water cooling systems, which are essential when drilling tiles and stone.

Stone drill bits are specifically engineered for tough materials like concrete, masonry, and natural stone. Thanks to their premium materials and optimised drill tips, they drill precisely without chipping or cracking. This is vital to avoid damaging the workpiece.
With a stone drill bit, you can confidently tackle even the most resilient surfaces cleanly and quickly. They are perfect for fixing installations or working on stone slabs in everyday use.
Drilling into tiles, ceramics, or glass demands special care: the risk of cracking or breaking tiles is high. Tile drill bits come equipped with diamond tips designed to protect the material and create clean, precise holes without cracking.
Whether mounting sanitary fittings, brackets, or electrical sockets—you can work quickly, safely, and achieve professional results with tile drill bits. This allows for gentle handling of sensitive materials.
For particularly hard materials like natural stone or porcelain tiles, wet core drill bits are the ideal solution. They are cooled with water, preventing overheating and significantly extending the life of the drill bit. Continuous cooling ensures clean, accurate holes and protects the material from damage.

Wet core drill bits are commonly used when installing anchors, routing cables and pipes, or cutting openings for sockets. We supply both wet core drills and compatible accessories.
To maximise the lifespan of your drill tools and achieve the best results, keep the following in mind:
Drilling speed and pressure: Work at moderate speeds with steady pressure. Excessive pressure can damage drill tips, while too slow speeds unnecessarily prolong working time.
Cooling: Constant water cooling is essential, especially when working with natural stone and porcelain tiles, to avoid heat build-up.
Pre-drilling: For very hard or sensitive materials, it’s advisable to start with smaller drill diameters and work up gradually.
Tool maintenance: Clean and dry drill bits thoroughly after use. Diamond-coated core bits should be regularly checked for wear.
The quality of your tools directly affects your work results and efficiency. Cheap drill bits tend to dull quickly or damage materials, causing costly rework. High-quality drill bits and drill stands from Karl Dahm offer long durability, high precision, and help ensure a smooth workflow.
Precise drilling is also crucial for the safety of the entire installation—especially in plumbing and electrical work. This prevents expensive repairs and guarantees professional workmanship.

Wet Core Drill Bits: Optimally diamond-coated for long service life.
A drill stand is essential for tilers because it holds the drill firmly in place and ensures a smooth, controlled drilling motion. On hard or brittle surfaces like ceramic, porcelain stoneware or glass, even a small slip can cause scratches or cracks. The drill stand prevents this by stabilizing the tool and allowing perfectly straight and clean drilling results. This is especially important in visible areas where accuracy and aesthetics matter. Additionally, the drill stand improves working safety and reduces physical strain, as less manual pressure is needed.
Masonry drill bits are specially designed for drilling into hard and abrasive materials such as concrete, granite, brick or natural stone. Their reinforced tips made of tungsten carbide or diamond coating withstand high heat and pressure levels. This allows them to drill through solid surfaces smoothly without becoming dull or breaking. In contrast, standard drill bits intended for wood, metal or plastic lack this strength and would fail quickly. Masonry drill bits ensure clean, stable holes and are indispensable on construction sites and renovation projects.
Wet core drill bits require water cooling to ensure efficient and safe drilling. When drilling into tiles or stone, friction generates high heat that could damage the diamond coating of the drill bit. The water cools the drill bit, preventing overheating and extending its lifespan. At the same time, the water binds and flushes away drilling slurry, leaving a smooth, clean hole. This method reduces stress on both the tool and the material, preventing cracks and ensuring perfect drilling results even in very hard surfaces.
Tile drill bits, especially diamond-coated versions, are ideal for drilling glass. Glass is extremely sensitive to stress and can crack easily if drilled incorrectly. Therefore, it is important to use a low rotational speed and apply only slight pressure. Water cooling is recommended to reduce heat buildup and internal stress. With the precise and controlled drilling method of tile drill bits, clean holes can be made in mirrors, shelves, glass panels or windows without chipping or breaking.
Wet core drill bits should be used with a drill machine that either has an integrated water supply or is compatible with an external water cooling system. It is also important that the drill provides sufficient power, as hard materials like porcelain or granite resist pressure. Adjustable speed control allows matching the rotational speed to the drill bit size and material. Using the right drill machine ensures precise, clean and smooth hole results even in tough materials.
Drill stands are typically mounted using strong pump-operated suction pads that firmly attach to smooth or lightly textured surfaces. For large-format tiles or uneven substrates, additional mounting kits with extra suction pads and angle brackets ensure maximum stability. This prevents slipping and allows accurate drilling, even on delicate or large tile surfaces. The secure mounting is essential for safe, precise and professional drilling work.
To maintain high drilling performance, masonry and tile drill bits must be cared for properly. After each use, remove dust and material residue to prevent clogging and wear on the cutting surfaces. Diamond core bits should be inspected regularly to check the condition of the diamond segments. Store the drill bits in a dry, protected place to prevent corrosion and physical damage. With consistent care, drill bits remain sharp longer and deliver better drilling results.
Karl Dahm drill stands support a wide range of drilling diameters, making them suitable for nearly all tiling and installation applications. The KDB-200 drill stand allows drilling from 6 mm to 120 mm, while the KDB-201 model supports hole sizes up to 125 mm.
