Sintered Diamond Core Drill

The Sintered Diamond Core Drill is engineered for high-performance drilling in ultra-hard materials like stone, glass, ceramics, and metals. Its sintered  diamond matrix ensures unmatched durability and precision, making it indispensable for industrial, lapidary, and artistic workflows. Engineered for professionals who demand durability, accuracy, and long-lasting performance, our Sintered Diamond Core Drill deliver exceptional results across a wide range of materials. Unlike conventional plated or brazed alternatives, these bits feature an industrial-grade sintered diamond bond—embedding diamond particles throughout the entire matrix for a lifespan up to 3 to 5 times longer.

Whether you're a lapidary artist drilling gemstones, a stone fabricator working with granite or marble, or an industrial machinist handling aerospace alloys, these core drills ensure clean, burr-free holes in even the toughest materials including ceramic, tile, sapphire, and hardened metals.

Unlike standard diamond drills bits for stone, sintered  bits maintain edge sharpness, resist heat, and offer superior cutting efficiency—making them ideal for long-term professional use. They’re compatible with rotary tools, CNC machines, and sintered  diamond Dremel bits setups.
