I need to cut down a chipboard kitchen carcass - soft material but needs a clean cut on one side (other side will be covered by end panels, etc)..

My instinct is "12 teeth !", now go and look for another finer tooth blade (say 40 or more).

This any help:

Well thats what I would have thought !

170mm diameter seems to be rare. Perhaps Ryobi is not so good for circular saws.

Anyway, 165mm is common, and only could affect cut depth by 2.5mm. Any problem using something like this:

Well just for feedback, this blade is doing a good job on kitchen worktop (sawn face down). Just remember to check the direction of rotation - this blade needed fitting with the label side into the saw. Although you would stupid not to notice if the teeth were facing the wrong way when you spun the thing up !
