About This

• Complete Set of Diamond Core Drill Bits: This 5-pack includes sizes 3/16" (5mm), 1/4" (6mm), 5/16" (8mm), 3/8" (10mm), and 1/2" (12mm), making it great for a wide range of drilling needs, including glass, tile, ceramics, stones, and masonry brick.
• Dry Drilling Innovation: These diamond drill bits feature a wax lubricant on the inside that prevents diamond loss and prolongs the life of the bits. This technology, combined with its integrated coolant system, helps the bit remain cool and dry during use. To maintain optimal performance, we recommend pausing and cooling the bit after each individual hole.
• Clean and Precise Drilling: Each bit in the set is designed with vacuum brazed diamond technology to ensure precise and clean drilling in tiles, porcelain, granite, ceramic, glass, marble, stone, and masonry brick (not for wood). The innovative Side Flute design removes debris quickly, and the Depth Mark on the side ensures precise drilling.
• Compatibility: The Round Shank design is compatible with most popular electric drills, angle grinders, and bench drills for added convenience.
• Heavy-Duty Storage Case: This set comes in a sleek and durable storage case for easy access and safe keeping. In addition, our first-class customer service team is always available to provide assistance should you need it. Whether you're a professional mason or a DIY enthusiast, this set has everything you need to get the job done quickly and efficiently.
