Tips:
Hole saw may become overheated and get damaged or even burned up due to fast rotary friction, we suggest customers to use
cutting fluid to keep the hole saw cold during usage.
Keep the drill be stable when drilling, otherwise the centre bit may get snapped due to excessive shaking.
Start drilling with a slow drill rotary speed, or the centre bit may be shattered on first use.
The larger the hole saw is, the slower the drill rotary speed should be, this way can protect the centre bit from getting snapped.
