Versatile Core Drill Bits for Hard MaterialsThese diamond drill bits are specifically crafted for effective drilling on a variety of tough surfaces, including glass, tile, marble, granite, porcelain, ceramic, and stone. The continuous rim and segmented diamond edge designs provide clean, fast cuts, making them an excellent choice for both industrial and artisanal applications such as marble and glass cutting, tile drilling, and stonework.
Superior Design & CompatibilityElectroplated and polished finishes protect the diamond grit edge, ensuring longevity and consistent performance. Designed for high-speed cutting (up to 12,000 RPM where applicable), these bits are suitable for use with standard electric drills and angle grinders using the appropriate mounting adapters. Oblong, side-vented slots help with rapid chip ejection and cooling during operation.
Extended Bit Life & Safe OperationUsing water as a coolant is essential to prolong the life of the diamond drill bit, minimize heat build-up, and achieve optimal results. Each bit is engineered to deliver up to 100+ holes on standard materials like glass or ceramic, though performance may vary depending on application and material hardness. Convenient blister pack or plastic box packaging ensures safe storage and easy access.
FAQs of Diamond Drill Bits:
Q: How should I properly use diamond drill bits on glass, tile, or stone surfaces?
A: Ensure the target surface is secured and apply steady pressure using high-speed electric drills or angle grinders (with suitable adapters). Always keep the bit cool with water to prevent overheating, extend bit life, and achieve cleaner cuts. Start drilling at a low speed until the bit establishes a groove, then gradually increase to the recommended RPM.
Q: What materials are suitable for these core drill bits?
A: These diamond drill bits are purpose-built for glass, tile, marble, granite, porcelain, ceramic, and various stone surfaces, making them ideal for both industrial and artisanal applications where precision and durability are required.
Q: Where can these drill bits be mounted and which tools are they compatible with?
A: They are compatible with electric hand drills and angle grinders when used with the appropriate mounting adapters. Available drive types include hex shank, SDS Plus, and round shank configurations (varies by model), ensuring wide compatibility.
Q: What is the recommended process for maximizing bit life and performance?
A: Always use water for cooling during drilling. Begin at a low speed to create an initial groove, then transition to higher speeds as needed. Allow the drill to do the cuttingavoid excessive pressureand clear chips regularly using the oblong/side-vented slot design.
Q: What variations in size and segment types are available for different applications?
A: Multiple size options are offered, such as 6mm, 10mm, 18mm, 32mm, 40mm, 50mm, 65mm, and up to 120mm, with segment styles including continuous rim or segmented models (depending on bit size and intended use). This flexibility allows for customized drilling across diverse project requirements.
Q: What are the primary benefits of using diamond drill bits with an electroplated/polished finish?
A: The electroplated or polished finish enhances the tools durability, reduces friction during use, and ensures smooth, precise cuts on hard surfaces. Combined with high cutting speeds (up to 12,000 RPM) and support for water cooling, these bits guarantee efficiency and extended service life.
Q: What is the minimum order quantity for these drill bits?
A: Minimum order quantities depend on the supplier but typically start at around 10 pieces per size. This allows for tailored procurement based on your specific project or inventory needs.
