Von wegen 1-15 cm - You can also expand on the diameter of 18.2!

For this circle cutter almost everything has already been said. It cuts clean circles, if you manage to keep the center point exactly. Unfortunately, he has no useful scale to adjust to the millimeter, but with a scale, it should go. The blades are very sharp, and the device is easy to use. So far so good!

As for the possible radius, so you can reach by turning the needle unit has a maximum radius of 18.2 cm. Just get out turning the brass screw, pull out the black plastic part, turn around and reinsert it.

For the low price and the easy handling from me it 5 stars!
