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
