How to use a hand drill to drill holes in the glass/tile/stone?

Step 1. The bit on the glass/tile/stone 45 degree, open a half-moon notch on it

Step 2. Slowly up the bit to 60 degrees, and then gently drill

Step 3. Reached 90 degrees, continue to drill

Step 4. Drill through the glass/tile/stone finally, the technique requires a "wobble" of the drill rather that steady pressure straight on
