High-Quality Diamond Drill Bits: These tile drill bits feature sharp, extremely hard diamonds, ensuring professional, clean, and fast drilling. High-quality diamond drill bits are abrasion-resistant, durable, and long-lasting, offering a fast cutting speed. Waterless Drilling: These diamond drill bits provide efficient and clean drilling. Filled with cooling wax, they cool and lubricate the drill bit, allowing you to drill holes without adding water, making them suitable for dry drilling. Wide Applications: Perfect for easily drilling holes in glass, marble, tiles, blocks, fiberglass, slate, granite, ceramics, hard floor tiles, stone slabs, and hard tiles. Works with all electric drills and angle grinders. Stable and Durable: These diamond drill bits are designed for dry drilling, providing stable drilling. Furthermore, they have a long service life thanks to their high-quality, temperature-resistant diamonds. Vacuum brazing is the most efficient and precise way to manufacture diamond tools. It allows us to improve the material removal rate and extend tool life. Hexagonal Shank: Hexagonal shank and tight locking mechanism, suitable for any electric drill, hand drill, or bench drill. Prevents drill bits from slipping and improves your work efficiency. Cooling Wax Inside: Inside is a special cooling wax that can be used to cool and lubricate the drill bit during drilling. Easily drill holes without assistance and spend less time drilling. High-Quality Material: High-hardness diamonds firmly attach to the steel body using vacuum brazing technology. Our diamond drill uses high-quality artificial diamonds, which are sharp, thick, and durable. Dry Drilling Without Water: Our diamond hole saw sets can drill dry without water.
