The HARDROCK Diamond Core Bit D32mm is a precision drilling tool designed for high-performance cutting in hard materials such as granite, concrete, ceramic tiles, and marble. With a 32mm diameter, this core bit is ideal for creating clean, accurate holes in both construction and renovation projects. It features industrial-grade diamond segments that ensure fast penetration and extended tool life, even when working with dense substrates. The bit is compatible with rotary drills and core drilling machines, and its robust design allows for both dry and wet drilling, depending on the application and material.
To maximize efficiency and prevent overheating, the bit should be used with water cooling, especially when drilling into tiles or stone. Its no-pilot design requires a steady hand and low RPM operation, typically with a planetary gearbox or cordless drill set to its lowest gear. The HARDROCK core bit is built to withstand high temperatures—up to 500°C—and delivers smoother cuts with less vibration compared to conventional bits. Whether you’re installing plumbing fixtures, electrical conduits, or decorative fittings, this tool offers reliable performance and professional-grade results.
