Key Features

• Advanced Brazed Technology: Functions as both a drill and a grinder in one. Superior resistance to heavy impacts ensures precise, efficient performance on the hardest surfaces.
• Multiple Sizes Available: Choose from 6mm (0.24"), 8mm (0.31"), 10mm (0.39"), and 12mm (0.47") diameters to suit a wide range of drilling tasks.
• Rapid Penetration: Cuts through hard materials like marble, ceramics, glass, and red brick at impressive speed — creating perfect circular, smooth holes in just seconds.
• Built-In Cooling Wax: Each bit contains embedded cooling wax that melts during operation, providing internal lubrication and heat dissipation. This intelligent dry-drilling system prevents overheating and significantly extends bit life.
• Multi-Function Tool: Not just for drilling — also performs edge grinding and trimming for a perfectly flat, refined finish. One tool handles hole drilling, edge processing, and surface refinement.

Frequently Asked Questions

Q: Can these diamond core drill bits be used without water?

A: Yes! These bits are specifically designed for dry drilling. Each bit contains embedded cooling wax that melts during operation to lubricate and dissipate heat, eliminating the need for water. This makes them far more convenient for indoor tile and stone work.

Q: What materials can these diamond core bits drill through?

A: These diamond core drill bits are compatible with a wide range of hard materials including ceramic tile, porcelain, granite, marble, glass, microcrystalline stone, and red brick. They are not recommended for wood or soft plastics.

Q: What size drill is needed for the hexagonal shank?

A: These bits feature a standard hexagonal (hex) shank that fits most common electric drills and rotary tools. Simply ensure your drill chuck accepts hex shank bits — most modern drills do.

Q: Can I use these bits for edge grinding as well as drilling?

A: Absolutely. These multi-functional bits are designed not just for hole drilling, but also for edge grinding, trimming, and surface refinement, making them a versatile addition to any toolkit working with tile or stone.
