This all-in-one tile drill bit set fit porcelain tile, ceramic, glass, marble, granite, stone, jade, etc. Covers a wide range of applications: kitchen & bathroom renovation, home & commercial decoration, auto repair, equipment maintenance, outdoor furniture & fence installation
- No More Wandering or Slipping: Our glass drill bit set includes a pilot bit that new users can first drill an accurate dimple, then drill at a 45° angle with the diamond hole cutter to prevent slipping on smooth surfaces and protect your expensive tiles from scratches.Always maintain proper drilling speed and avoid excessive pressure, so as to prevent ceramic chipping. The tool protects your costly tiles from scratch damage and delivers neat, perfectly sized holes for delicate ceramic tiles, glass bricks, etc
- High-Carbon Steel & Vacuum Brazing: This diamond core drill bit set uses a premium high-carbon steel body with advanced vacuum brazing technology. Industrial-grade diamond grit is firmly brazed onto the bit body. Compared to standard electroplated diamond drill bits, our vacuum brazed diamond drill bits offer higher hardness, superior wear & corrosion resistance. The upgraded high-carbon steel shank resists bending and breaking, delivering longer service life than conventional electroplated bits
- Built-In Wax Cooling & Cooling Performance Upgrade: Each porcelain tile drill bit is pre-filled with premium cooling lubricant wax that melts automatically during drilling to cool the cutting surface, reduce friction, and prevent diamond grit shedding. This design eliminates the need for continuous water supply in dry drilling, ensuring high-efficiency cutting and extending diamond drill bit life.Ideal for quick dry-drilling tasks on bathroom walls or kitchen backsplashes where water use is inconvenient. For hard materials like granite and marble, wet drilling with water provides a longer lifespan. The diamond tip drill bit are optimized for both dry and wet drilling

Widely suitable for ceramic tile, porcelain tile, ceramic floor, glass, marble, granite, natural stone, jade, glass bottles, ceramic pots, bathroom tiles, kitchen backsplash, stone countertops, etc. (NOT for concrete, metal, steel, wood, plastic).
