Hole saws are drill bits that consist of a saw blade holder and a central pilot drill bit which determines the position of the hole. Often, interchangeable saw blades are locked on the holder one at a time.
We currently have a set of wood hole saws that can cut 44 mm deep and 26, 32, 39, 45, 51, 58 or 64 mm in diameter.
There is significant kickback when (mis-)using this tool, take the time do it right!
Proper Use
Put only a single saw blade into the holder when you want to use it!
Use a drill at relatively high speed but little pressure.
| ⌀ | max rpm |
|---|---|
| 26 - 39 mm | 1200 |
| 45 - 58 mm | 1000 |
| 64 mm | 800 |
No hammering drill can be used to saw holes.
Besides keeping the saws intact, please take personal safety precautions and wear safety goggles!
Past Issues
2018-3: the screw broke out of the aluminum blade holder - fixed by drilling/tapping a new hole opposite of it
