Circular saw for cuts square enough for pocket hole joinery?

[Joe]

Any recommendations for a circular saw that would make cuts sufficiently square for good pocket hole joints? Preferably a saw with a dust chute/shop vac attachment. 

I was looking at the Bosch CS10, for which Bosch offers a dust attachment, but the reviews mention that the saw motor isn't mounted to the base plate, and when pushing down on the handle, there is a bit of flex that moves the blade out of square relative to the base plate, meaning the cut won't be a perfect 90* cut.

I use a half dozen different circular saws and have for many years.

When properly setup and using a suitable guide, they make accurate 90 degree cuts.

Feed and speed is key.

If you force the cut, it may veer off the intended cut line.

The Bosch CS10 is an excellent saw.

Perhaps the person who wrote the review, wasn't using the saw correctly.

I've experienced no flex in the handle, in the one I've used.

Most circular saws will cut 90, when properly set and using a suitable guide.

Peruse saws at your local stores---pick out what you like---

It's got to feel right to you---balance and grip--- or else you won't like it.

Take it home try it out for yourself.

Most offer 30 day return policy. It don't like it, return it and exchange for another.

BTW---one must have a firm grip on the handle and guide the saw thru its cut.

Don't force feed it---the tool do the work.

Use good blades and thicker blades for best results.

I've got the Bosch CS10 and have not experienced the flex mentioned.  I've used it to cut 3/4" plywood panels for my bench, which is assembled using my Kreg K4 and the appropriate fasteners.  The bench is as solid as can be.

BTW, even with the vacuum adapter on the CS10, you will still have sawdust flying about, just a lot less of it.  Without the vacuum hooked up, it will coat your right arm in sawdust.

Ken mentioned checking out the local stores.  That is exactly what I did to find the CS10.  It was tough finding a saw to replace my old and well-used Craftsman.  When you are checking, be sure to look at depth setting, angle settings, trigger, cord length, blade changes.  The only thing I don't like with the CS10 is that it has no on-board blade wrench storage like the old Craftsman did.

I made my own jig to do cross cuts.  Since I don't have room for a table saw, I've used this jig to make perfect 90degree cuts.

I think it would be pretty hard to do consistently.  Maybe if you bought a track saw?  but those are pricey as well.  I ended up buying a cheap kobalt table saw.  It works decent, but the fence is not that good.  It does do good enough though for the projects i have been working on.  Pretty much get what I paid for out of it.  In a perfect world I'd have the space and money to have a really nice 1200 dollar tablesaw, but this isn't a perfect world.
