USAGE SUGGESTION:
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.
PACKAGE INCLUDES:
7 x Hole Saw Drill Bit

| OPERATING INSTRUCITONS | |
| ·Insert the hole saw into the electric drill. | |
| ·Secure the drill chuck jaws on three flats of hole saw shank. | |
| ·Begin drilling using light feed pressure until the hole saw has begun drilling. | |
| ·Apply medium feed pressure once the cutter has engaged in material. | |
