Our Diamond Sintered Core Drills are engineered for precision cutting and long-lasting performance on a wide range of materials, from fragile glass, ceramics, and crystals to ultra-hard surfaces like steel, marble, and granite. Crafted with an exclusive metal bond, these core drills combine strength, durability, and high cutting efficiency, making them the ideal choice for professionals and hobbyists alike.

Key Features

• Sintered Diamond Construction: Diamonds are embedded throughout a heavy-duty metal matrix, not just plated on the surface, ensuring superior longevity and consistent performance.

• High Cutting Efficiency: Rapidly drills through hard and abrasive materials with minimal effort.

• Durable and Long-Lasting: Can last 20–30× longer than nickel-plated diamond core drills, reducing replacement frequency.

• Precision Holes: Produces clean, accurate holes with minimal chipping, splintering, or cracking.

• Versatility: Suitable for concrete, masonry, natural and engineered stone, glass, ceramics, porcelain, and even metals depending on the bond type.

• Cooler Drilling: Efficient heat dissipation allows for safer drilling and prevents overheating.

• Wet and Dry Use: Compatible with both wet and dry drilling, though wet is recommended for cooling and dust suppression.

Specifications

• Size Range: Available from 3mm (0.12") up to 100mm (3.94") or larger, depending on your drilling needs.

• Design: Hollow cylindrical core with diamond-impregnated cutting edges for maximum performance.

• Diamond Bond: Metal matrix holds diamonds securely for durability in demanding applications.

Applications

• Construction & Renovation: Drilling holes for plumbing, electrical conduits, and anchor bolts in concrete and masonry.

• Stone & Tile: Perfect for sinks, faucets, and drainage installations in natural or engineered stone and ceramic tiles.

• Glass & Ceramics: Ideal for mirrors, glass panels, pottery, and precision ceramic drilling.

• Metalworking: High-precision drilling of hard metals and alloys.

• DIY & Hobby Projects: Craft projects, decorative holes in glass bottles, and custom jewelry making.

• Geological & Archaeological Use: Extracting core samples from rock formations or excavation sites.
