• 【Specifications】Hex Shank Diamond Drill Bits 1/4"(x2), 5/16"(x1), 3/8"(x1), 1/2"(x1)+1 Pack Drill Bits1/4". Features hex shank for anti-slip clamping, high torsion resistance, less breakage.
• 【Premium Material Upgrade】Crafted from industrial-grade diamonds, it offers exceptional durability. Its rigid body is upgraded to high-strength AISI 5140 alloy steel, effectively preventing bending and breakage. This addresses the issue of drill bits bending or deforming under high pressure and high temperatures, ensuring outstanding stability and accuracy during heavy-duty use.
• 【Vacuum Brazing Technology】Using advanced vacuum brazing technology ensures a strong bond between high-quality diamonds and the steel body, tripling the drill bit’s durability and providing high-temperature resistance, thereby extending its service life.
• 【Versatile Compatibility】 Designed specifically for a wide range of hard surfaces, including porcelain, tiles, ceramic, granite, marble, concrete, masonry, and glass. Ideal for home renovation projects, such as bathrooms, kitchens, and walls.
• 【Instructions: Wet/Dry Drilling】 Keeps your workspace clean and tidy—no mess: The built-in cooling wax core absorbs heat, allowing for quick, short-term dry drilling. Note: For extremely hard natural stone, or to maximize the tool’s lifespan, we strongly recommend using water for additional cooling and lubrication to improve efficiency.
