I would not scribe cuts with circular saw, and doubt Keitai understood any of that .Well occasionally you do need to finish against a rough brick wall (with a scribed gap and something like Compraband to fill the gap), or against cast concrete again with a scribe cut, or even to a metal window frame - all of which will leave a cut/scribed edge which cannot be hidden by undercutting or by using a quadrant bead. Not common, but they do happen
Straight line scribe to a metal window, a concrete wall or a polished plaster wall? What about scribed to the bottom of stairs (especially with a rounded end bottom step)? Or even whete your last plank ends up.being a ripped cut. There are times you do need a circular saw to make a straight cut. As for the language, sorry but how else can I describe those circumstances?I would not scribe cuts with circular saw, and doubt Keitai understood any of that .
Not the fibre cement blade then. Someone in shop said laminate won't blunt it
Oh well, and that's the only criteria? For your information, once you use a cutter of any description on a hard material it won't cleanly cut anything softer. Examples include files (once you file steel with them you can forget about using them effectively on aluminium or brass), and saw blades used on cement board. An we all know you used that blade on cement board...Not the fibre cement blade then. Someone in shop said laminate won't blunt it
Use a guillotine for all cuts that will be hidden (99%); no dust and very quick.
For the 1% visible cuts, use a mitre saw with a new blade with at least 48 teeth.
Lightly score the visible face first and then cut fully.
For scribing around door frames, use a dedicated good quality jigsaw blade, although I have used bosch wood blades and they don't chip anything.
But as mentioned, 99% if not 100% of the cuts should be hidden.
Not rocket science.
Forgot to mention: if you weight less than 200lb/90kg, you'll struggle with the guillotine.
