- Use low speed when drilling (usually keep in 2000r/min - 3000r/min). Too fast speed will off center, break the bit or jammed
- When drilling the hole, please adjust according to the hardness of the wood. If the wood is soft, you can choose the smaller center drill bit. If the wood is hard, you can choose the corresponding or bigger one
- If you can't get the center drill bit out after drilling, use the hex key to separate the drill bit
