Diamond Core Drill Bit Set, 7-Piece (for Tiles, Concrete, Stone)

The diamond core drill set is designed for situations where ordinary drills simply give up. This tool allows for exceptionally precise drilling in stoneware, ceramics, natural stone, granite, marble, and concrete. Thanks to vacuum-brazed diamonds, you will achieve clean hole edges without cracks or material chips. It is an ideal solution for professional builders and tilers, as well as for craftsmen seeking excellence in home projects.

Features:

• Longevity and Durability: The above-average height of the diamond cutting part (15 mm) guarantees a significantly longer service life compared to standard core drills.
• Double Diamond Layer: Internal and external diamond coating substantially increases drilling speed and eases the process.
• Vacuum-Brazed Diamonds: This technology ensures fast and smooth drilling without risking the aesthetic of the processed surface.
• Maximum Efficiency Without Overheating: Smaller diameter drills (6, 8, 10 mm) are filled with special cooling wax, while larger ones have ventilation holes that effectively dissipate heat.
• Universal Compatibility: The standard M14 thread is suitable for angle grinders, while the included adapter allows them to be used with a standard drill as well.
• Conical Core Drill (2–50 mm): The included conical cutter allows for precise corrections, milling, and widening of existing holes.
• Secure Storage: All tools are organized in a durable aluminum case, which protects them from damage and helps maintain order in the workshop.
