\n
\n<\/span>\n<\/p>\n

\nPremi<\/span>um Vacuum Brazed Technology<\/span><\/span>\n<\/p>\n

\nFAST & NEAT DRILLING: Powerful drilling bit guarantees high drilling speed, neat, round and smooth opening without gap.<\/span><\/span>
\n<\/span>\n<\/p>\n

\nApplicable to<\/span> porcelain, ceramic drilling, <\/span>granite, marble, stone brick, ceramic tile, etc<\/span>.<\/span><\/span>\n<\/p>\n

\nFeatured with good concentricity, more stability, high efficiency, <\/span>long<\/span> lifespan,less Chipping,<\/span>Fast and Smooth drilling<\/span><\/span>.<\/span><\/span>\n<\/p>\n

\n\n<\/p>\n

\nOther Description<\/span>\n<\/p>\n

\n??<\/span><\/span>LARGE CHIP REMOVAL HOLE DESIGN: Large chip removal hole design reduces cutting resistance for easier drilling.<\/span>
\n??<\/span><\/span>STANDARD SCREW HOLE DESIGN: Standard screw hole design, high quality screw hole interface, more convenient for loading and unloading the drill bit.<\/span>
\n??<\/span><\/span>ADVANCED PROCESS TREATMENT: Brazed diamond process for increased wear resistance and service life, and paint spraying treatment prevent drills bit from rusting.<\/span>
