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.
Key Features
-
Durable Sintered Diamond Bond:
- A wear-resistant matrix retains diamond particles for sustained cutting performance.
- Outlasts plated drills and brazed tools by 3–5x.
-
Precision Engineering:
- Delivers clean, burr-free holes for lapidary tasks like drilling gemstones or art glass.
-
Versatile Material Compatibility:
- Ideal for granite, marble, ceramic tiles, and hard alloys.
Applications
- Lapidary & Jewelry: Drill holes in sapphires or beads for jewelry settings.
- Stone Fabrication: Create openings in countertops or monuments.
- Industrial Metalworking: Precision drilling in aerospace alloys or tool steel.
