Hi there

I recently inherited a circular saw from my grandfather. Until I got it, I was convinced I didnt need one, the table saw was fine. Now I have it, I’ve used it every weekend.

The saw is a craftsman 7” “Electric Hand Saw” which means circular saw today. It may have had the original blade on it (he only ever cut 1/4” ply and PVC as far as anyone can remember). I replaced it with a 6.5” Freud Diablo 40t to cut up some 3/4” ply, and that worked well. This saw is quieter than some new saws I’ve used.

I’m looking for advice on a couple things. As to the blade, this $15 Diablo seems alright, carbide tips, cutouts, all that. Am I better off sticking with this smaller blade, are there decent wood cutting 7” blades for sale somewhere I havent looked, should I be able to use a 7 1/4” blade safely?

Second, the base is stamped, and the miter adjustment leaves a lot to be desired. It’s a regular nut (may have been a wingnut originally?) so it requires a wrench, and when I got it, the base would run in to the top blade guard at about 42 degrees. A file took care of that (just about 1/8”, so no safety issue) but I was surprised. Are there aftermarket bases that I just haven’t been able to find?

Last, anything I should do to keep it running? I put a few globs of lithium grease in the arbor, it was full of sawdust and plastic dust. The cord is good.

Thanks for any reply.

Most likely the 7 1/4” blades will NOT fit. On the one 7” sears saw I have experience with, the larger blade hit the guard, and even if it doesn’t on yours it will be sitting way to close.

There is nothing wrong with the 6.5” blade unless you need the extra 1/4 cut depth. There are 7” blades available if you dig, I did a little digging and came up with www.carbide.com don’t know anything about them, and the 7” blades they are seem pretty pricy, but I guess it depends on what you want to do with the saw.

If you have the model number you may be able to find parts still from sears. Searspartsdirect.com but I don’t believe sears carries the 7” blades anymore.
