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.
If you need guidance without the pilot drill bit (e.g. when cutting around a hole that is already larger than the pilot drill bit, or if you need discs without a hole), try clamping a template cut with the same hole saw on top of your workpiece. [1]
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!
Available Sizes
Bosch "Progressor Electrician" set: 19, 25, 38, 44, 68, 83 mm in diameter
- can be expanded with further saws that are compatible with the "Bosch Power Change Plus" system!
Past Issues
2018-3: the screw broke out of the aluminum blade holder - fixed by drilling/tapping a new hole opposite of it
