The best battery-operated hand-held circular saw?
“The scheppach PL55Li is significantly more massive than our other two recommendations. No wonder, because it’s a plunge circular saw. The 36-volt machine achieves significantly higher speeds than the two mini saws and the maximum cutting depth of 55 millimetres is a record in the test field. The PL55 Li comes with an aluminium guide rail that is a good 140 centimetres long when connected.” (Excerpt from the test report on allesbeste.de)
