Diamond Drill Bits For Techincal Ceramics And Glass

Why Choose Gunther Diamond Tools?

At Gunther Diamond Tools, we specialize in custom diamond core drill bits designed for the toughest industrial applications, particularly technical ceramics and glass. Our drill bits are crafted in-house in Idar-Oberstein, Germany, using a proprietary diamond sintering process that delivers superior performance over competitors.

Whether you’re drilling advanced ceramics like zirconia or sapphire, or delicate glass for optics, our tools ensure clean, precise holes with minimal chipping and maximum efficiency.

Our Competitive Edge

• Unmatched Durability: Our sintered diamond drill bits last for hundreds of holes, far surpassing vacuum-brazed or electroplated bits from competitors.
• Proprietary Sintering Process: Ensures consistent diamond exposure for prolonged cutting efficiency.
• Custom Solutions: Tailored drill bits for your exact specifications, including custom diameters, lengths, and connections for your machines or ours.
• Core Ejector System: Prevents clogging, saving time and reducing waste.
• Alignment System: Eliminates blowout and backside chipping.
• Made in Germany: Full control over production ensures quality unmatched by outsourced competitors.

Applications in Technical Ceramics & Glass

Our diamond core drill bits excel in demanding industries, including:

• Advanced Ceramics: Drill zirconia, alumina (Al2O3), silicon carbide, and sapphire with precision for electronics, aerospace, and medical components.
• Glass & Optics: Create clean holes in optical lenses, glass substrates, and sapphire for research and manufacturing.
• R&D and Labs: Trusted by universities, military research, and commercial labs for preserving material microstructure with minimal damage.

Unlike general-purpose bits, our tools are optimized for hard, brittle materials, ensuring faster drilling and longer tool life.

Technical Specifications

Why Our Drill Bits Outperform

Competitors offer solid products, but their bits often lack the specialized engineering required for technical ceramics and glass. Some competitors focus on DIY and general-purpose drilling, compromising on precision for cost. Some offer industrial options, but their outsourced manufacturing and standard bonding methods can’t match our quality control and durability. Our drill bits are designed for professionals who demand perfection.
