The Ioan™ 1/4″ (6mm) Diamond Drill Bit is a precision tool engineered for mounting bathroom accessories, mirrors, and electrical fixtures. Small diameter bits are highly susceptible to overheating; to counter this, our 6mm bit is filled with a specialized cooling wax. As you drill, the wax melts, absorbing heat and lubricating the diamonds for a clean, non-aggressive cut. This technology allows for fast dry operation while maintaining the tool’s integrity. If your project requires a specific size not listed, we offer custom sizing upon request.
