I'm a very keen DIY'er and getting on a bit and have managed with just a jig saw,until now. Wish I had bought this circular saw years ago. I'm left handed and understood the implications when I bought it, however, the saw is well balanced and I do not find it difficult to use, the cleanness and accurateness is astounding giving the price paid. Plenty of power, I dare not use it on metal I know it (the blade)can do it but how long for? prefer to keep it in good condition for timber. When set at 0' or is that 90'? it goes slightly beyond so you have to be aware of that and just keep an eye on it, perhaps it's just my machine? an easy fix with a bit shendanagans :-) thoroughly recommended
