Pro-Tip: To start a hole in smooth tile without a pilot bit, hold the drill at a 45-degree angle to the surface. Start the drill at a slow speed and slowly tilt the saw upright as it begins to grind a groove. Always use water to cool the bit; this prevents the diamonds from overheating and significantly extends the life of your hole saw.
