6-Piece Dry Diamond Drill Bit Set for Porcelain, Tile, Ceramic, Pot, Glass, Granite, Concrete, Masonry, Stone, Hard Materials, Tile Drill Bits 1/4",5/16",3/8",1/2"&Tungsten Carbide Bit 1/4"

【Precision sizes for standard anchors】This 6-piece set provides the exact diameters needed for common installation tasks: 2x 1/4"(6mm), 1x 5/16"(8mm), 1x 3/8"(10mm), and 1x 1/2"(12mm) diamond bits, plus 2x 1/4"(6mm) tungsten carbide bit for precise centering. Perfectly matched for installing towel bars, mirrors, floating shelves, and bathroom brackets into standard anchor sizes with professional accuracy.

【AISI 1045 steel body & high rigidity】Constructed with a professional AISI 1045 high-carbon steel body and industrial-grade diamonds. This high-rigidity construction effectively solves the common issue of drill bits bending or snapping under high pressure and intense heat, ensuring superior wear resistance and a significantly longer life for your toughest heavy-duty jobs.

【Vacuum brazing for 3x extended lifespan】Enhanced with advanced Vacuum Brazing technology, which fuses high-quality diamonds permanently to the steel body. This creates an exceptionally strong bond, making these bits 3 times more durable than standard tile bits and significantly increasing their resistance to high temperatures during continuous use.

【Versatile for kitchen & bath renovations】The ultimate solution for drilling into porcelain, ceramic tile, granite, marble, concrete, masonry, glass, and more. Specifically designed for kitchen, bathroom, and wall renovations, providing clean, precise holes without cracking or splintering, even when working on the hardest tile grades.

【Usage instructions: dry & wet drilling】Features a built-in cooling wax core that absorbs heat, supporting efficient short-term dry drilling for quick indoor tasks without the mess. Note: For extremely hard materials or to maximize the tool's lifespan, using water for additional cooling and lubrication is highly recommended to maintain peak performance and efficiency.
