Diamond Core Drills

Diamond Core Drills from Braemar USA deliver high-accuracy drilling in the hardest and most brittle materials used in optics, semiconductor manufacturing, aerospace, and advanced ceramics. These precision diamond drilling tools use premium synthetic diamond and tightly controlled metal bond formulations to give clean entry, minimal chipping, and accurate hole geometry. As a result, they run with long, predictable tool life, even under demanding daily production loads.

High-Performance Metal Bond Diamond Cutting Technology

Braemar machines each drill from a precision-ground steel or carbide body, then applies a carefully engineered metal bond matrix. This approach gives uniform diamond exposure, stable cutting behavior, and strong thermal resistance. Moreover, the optimized bond reduces micro-cracks and subsurface damage, which protects brittle materials such as sapphire, quartz, and fused silica. Furthermore, when you need a free-cutting drill for thin ceramics or a long-life drill for quartz, Braemar designs consistently deliver reliable and repeatable performance.

Engineered for Hard & Brittle Materials

Braemar USA Diamond Core Drills work exceptionally well on:

• Sapphire (watch crystals, IR windows, LED substrates)
• Quartz & fused silica
• Technical ceramics (Al₂O₃, ZrO₂, Si₃N₄)
• Optical glass and borosilicate
• Composites, ferrites & silicon carbide
• Semiconductor substrates and other brittle materials

 

Because they cut cleanly and hold tight tolerances, these drills support precise work on highly fracture-sensitive parts. Therefore, manufacturers across high-tech industries trust them for consistent edge quality and accurate hole geometry.

• Precision Construction & Performance Features
• Premium synthetic diamond delivers fast, sharp cutting
• Tuned bond hardness supports coarse and fine-finish applications
• True-running geometry ensures accurate hole sizing
• Internal coolant channels improve chip removal and cooling
• Ultrasonic-ready designs support advanced micro-drilling

In addition, these drills perform reliably on CNC machining centers, ultrasonic rigs, optical fabrication systems, and high-precision manual setups. Ultimately, this versatility helps reduce scrap and improve production stability.
