Diamond Core Drill Bit Set, 13-Piece (for Tiles, Concrete, Stone)

The diamond core drill set is designed for tasks where ordinary drills fail. It provides exceptionally precise drilling in stoneware, ceramics, natural stone, granite, marble, and even concrete. Thanks to vacuum-brazed diamonds, you will achieve clean hole edges without cracks or chips. This set is engineered for a long service life and consistent results for both professionals and demanding DIY enthusiasts.

Features:

• Extended working life: The above-average height of the diamond cutting part (15 mm) ensures a significantly longer service life compared to standard core drills.
• Maximum speed: The double diamond layer (both inside and outside) substantially increases drilling efficiency and speed.
• Vacuum-brazed diamonds: This advanced technology guarantees fast and smooth drilling without risking the aesthetic of the processed surface.
• Versatility: The set includes core drills with diameters from 6 to 68 mm, making it suitable for a wide variety of mounting and installation tasks.
• Effective cooling: The core drills are equipped with cooling wax or special ventilation holes that prevent overheating and premature wear of the tool.
• Universal compatibility: The M14 thread is ideal for angle grinders, while the included adapter allows them to be used with a standard drill as well.
• Conical core drill (2-35 mm): An excellent tool for precise correction, milling, or widening of existing holes.
• Secure storage: All tools are organized in a durable aluminum case, which protects them during transport and helps maintain order in the workshop.
