The blade doesn’t spin fast enough and therefore the blade snags on the timber and is potentially very dangerous and therefore potential to do damage to your hand/fingers.
I was only cutting beading to go around a wood floor and took me so much longer cutting numerous times when it had snagged the beading whilst cutting the mitre
Provided you remember that this is an 18 volt battery tool you should not be disappointed. It is great for getting you out of trouble when there is no mains power for a transformer or you don't carry a generator. I have cut skirting and architrave for a two bed house and still had power left in a 5 amp battery. It will cut studwork and joists but these will drain the battery a lot quicker.
