Diamond Drill Bits 5mm 6mm 8mm 10mm 12mm Diamond Core Bits with Hex Shank for Ceramic, Granite, Glass, Porcelain, Tiles, Angle Grinders and Hand Drills

• High-Quality Diamond Drill Bits: Tile drill bits with sharp, extremely hard diamonds ensure professional, clean, and fast drilling. High-quality diamond drill bits are abrasion-resistant, durable, and long-lasting, with a fast cutting speed.
• Waterless Drilling: Diamond drill bits for efficient and clean drilling. Filled with cooling wax, it cools and lubricates the drill bit, allowing you to drill holes without adding water, making it suitable for dry drilling.
• Wide Applications: Perfect for easily drilling holes in glass, marble, tiles, blocks, fiberglass, slate, granite, ceramic, hard floor tiles, stone slabs, and hard tiles. Works with all electric drills and angle grinders.
• Stable and Durable: Diamond drill bits for dry drilling, providing stable drilling.

Furthermore, it has a long lifespan thanks to 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 the tool's lifespan.

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.

Wax Inside for Cooling

Inside is a special cooling wax that can be used to cool and lubricate the drill bit during drilling. Drill holes easily 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.
