I have some concrete repair to do and I am considering using a Skill HD77
worm gear circular saw and diamond blade to remove the old concrete. Does
this seem like a good approach? Any experience with this approach.
Anyone
have alternative ideas? I don't won't to go the rental approach because I
have a lot of small applications that I will be doing over many weekends
and
don't won't the expense of repeated rentals.

I assume that I will have to supplement the sawing process with hand cold
chisel work to completely remove the concrete, is that correct?

I would go to harbor freight, get the diamond blades, and an corded saw. I
would not use an good tool for cutting concrete. Spend as little as you can
on the saw. This saw should be treated as disposable.

You will need gfci protection cause you need to keep water on the diamond
bit. Even if they say "dry". The blades last a lot longer if you use some
water.

As others have said your just going to get part way through. (usually) and
then you will have to break out the rest. Sledge hammer works ok for this.
Consider a roto hammer/hammer drill for the removal.
