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 |

| 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!
