Description

The mini diamond-coated hole saw is engineered for precision drilling through glass, marble, tile, and granite. Its diamond plating delivers clean, chip-free cuts without requiring additional finishing work. For optimal results, use water or cutting fluid as coolant and drill at a slow, controlled pace. Begin at a 45-degree angle to the surface, gradually aligning to 90 degrees as the hole forms. This tool features no center pilot drill—pilots are unsafe for glass and stone applications. When hand drilling, start by creating a half-moon notch at 45 degrees, then gradually increase to 60 degrees before progressing to 90 degrees. Use a gentle wobbling motion rather than steady pressure for best results. Never operate in hammer mode. The design ensures professional-quality holes with minimal effort.
