What changes the bit choice?
Tile-rated geometry makes the difference
Do not confuse a tile bit with an ordinary metal twist drill. Choose tooling whose manufacturer approves it for the actual tile.
Use rotary mode through tile
Keep hammer or impact mode off. Control pressure and support where practical to reduce cracking.
Switch for the backing material
If the hole continues into brick or concrete, switch to a substrate-compatible bit after the tile layer. Check services before drilling.
Common mistakes to avoid
- Using percussion through brittle glazed tile.
- Assuming tile and porcelain are equivalent.
- Applying concrete-specific drilling instructions through a tile surface.
