Drills, core bits and jigsaws
Professional Drill Bits and Hole Saws for Perfect Openings
A clean, precise hole without cracks is the hallmark of a professional tiler. Our range features top-tier diamond drill bits, core bits, and hole saws specifically engineered for the toughest materials such as porcelain (gres), ceramics, marble, and granite. In addition to popular vacuum brazed tools, we offer premium drill bits with full diamond (sintered) segments, representing the highest grade of drilling technology. These bits are characterized by extreme durability, as the diamond grit is embedded throughout the entire volume of the segment, ensuring maximum efficiency when drilling into hard natural stone and heavy-duty tiles. Whether you require an M14 thread for angle grinders or a straight shank for power drills, our tools deliver industrial-grade results.

How to Choose the Right Tool for Drilling Tiles and Stone?
Working with modern materials, such as 2cm outdoor porcelain pavers or high-density ceramics, requires specialized technology. Conventional masonry bits fail quickly on these surfaces and risk cracking expensive tiles. At diamantovykotuc.sk, we specialize in tools designed for clean, fast drilling with an extended service life.
Key Technologies in Our Selection:
-
Vacuum Brazed (VB) Drill Bits: The ideal choice for dry drilling with an angle grinder. Diamond grains are vacuum-bonded to the tool body, providing an aggressive cut and high working speeds.
-
Sintered (Full Diamond) Drill Bits: Designed for professionals seeking maximum longevity. Unlike surface-coated tools, sintered segments have diamond grit evenly distributed throughout the metal bond. They are the gold standard for drilling granite, marble, and hard porcelain, often performing best with water cooling.
-
Wax-Filled Shank Bits: A practical solution for dry drilling with standard power drills. The specialized cooling wax inside the bit melts during use, extending the tool's life for smaller diameters (6 mm – 12 mm).
Our Range by Application:
-
M14 Core Drills: The best option for electrical installations, plumbing, and faucet holes (standard diameters: 35 mm, 68 mm, 72 mm, etc.).
-
Diamond Drill Bit Sets: A cost-effective and practical solution, keeping all essential sizes organized in a heavy-duty carrying case.
-
Grinding and Calibration Tools: Diamond milling cones and finger bits are invaluable for smoothing the edges of a drilled hole or slightly enlarging an opening without the risk of chipping.
Pro Tip for Longevity: When dry drilling with an angle grinder, use a "swiveling" or "oscillating" motion. Do not hold the bit perfectly perpendicular the whole time; instead, tilt it slightly and move it in a circular motion. This allows for better dust extraction and airflow, preventing the diamonds from overheating and significantly extending the life of your core bit.
