sourcing map Diamond drill bit for glass hole saw with center positioning bit for glass, ceramic, porcelain, tile 30 mm

General Description The 30mm diamond hole saw bit for glass is designed for precise drilling of materials such as glass, ceramics, porcelain, and tiles. Thanks to its center-positioning bit, it allows you to create clean, precise holes without chipping, while reducing cutting resistance and drilling pressure. Its white zinc coating offers excellent corrosion resistance, thus extending the tool's lifespan. Technical Specifications Diameter: 30mm Material: Diamond plated and brazed Coating type: White zinc Recommended drilling depth: Up to 1.2cm Compatibility and Accessories Suitable for electric drills (not included) Ideal for drilling glass, ceramics, porcelain, tiles, limestone, slate, marble, light stone, and fiberglass Not suitable for tempered glass, plastic, and wood Installation Start drilling diagonally to create a circle. Keep the drill straight during use. Use For efficient drilling, it is recommended to use water lubrication. Low drilling pressure and reduced speeds will prolong the life of the drill bit. Always use water for cooling during drilling. Other information: Diamond drill bits with clearance holes facilitate the entry of cooling water and the removal of chips. Diamond treatment types include sintering, electroplating, or brazing.
