This 8.0mm diamond-coated drill bit is engineered specifically for precision drilling in tile and glass applications. Operate at low speeds with moderate pressure to prevent material damage and bit degradation. Water cooling is essential throughout the drilling process to manage heat and extend bit life. Never engage hammer action, as impact forces will compromise the diamond coating and cause fracturing. For optimal results, apply masking tape to your work surface before drilling—this simple technique significantly reduces bit wandering on smooth, slippery surfaces. Switch to a standard twist bit once you've penetrated the tile or glass to complete your hole cleanly. Professional-grade performance for demanding installation and renovation projects.
