The 35mm Diamond Core Bit is a must-have for plumbers and stone fabricators, as it is the most commonly used size for creating professional tap hole openings. Designed to meet the specifications of standard single-hole mixers and basin taps, this bit allows you to drill directly into finished granite or natural stone with absolute confidence. Its high-torque design and diamond-bonded rim are optimized to grind through the toughest stone slabs, eliminating the risk of the shattering or “star-cracking” often caused by inferior tools.
Built for stability and precision, this bit features a reinforced shank that minimizes vibration, ensuring that the hole remains perfectly circular and centered. This is critical for tap installations, where a clean, uniform edge is required for the faucet base to sit flush against the counter. Whether you are working on a luxury kitchen renovation or a custom bathroom vanity, this 35mm core bit delivers the speed and professional-grade accuracy that high-end stone installations demand.
