My 18 volt Lithium ion circular saw, CCS180, came with the 18 tooth version of this blade. I got this one to get a little finer cuts. It does a nice job, giving a significantly smoother cut than the 18 tooth, while still being very effective. Amazing how well a battery powered circular saw cuts without using much battery power.
