For starters they are good quality and they are cheeper. I've bought a Dewalt 7 1/2 in. blade for 10.00 and the exact same blade in a 10" was 49.00. They are both the same brand and same teeth but it's almost 40.00 cheeper. It works the exact same way.I figure I might have come up with something. Hey, it works for me.
I also talked to someone in tools at my local Lowes when I was looking at the blades and noticed that a Black n Decker blade "in the package" costs more than a Dewalt "not in a package" and I asked "Why"?? He said you were buying the package. The Dewalt was a much better blade just with no package. I told him I would just throw away the package anyway.He said "right you are".He said most people don't look at the blades much unless it's in a package but I did and I will buy mine from now on "Without a Package". Give me your opinion????????? Donny
"Without a package" is called bulk pack, or contractor's pack. In the case of the DeWalt zillion tooth circular saw blades I use, at least, it is the same blade.
Only thing I would recommend is giving one a lookover before buying, just in case someone picked one up and dropped it.
On the bulk pack blades at HD or Lowes, look over a blade very closely before buying. Carbide teeth are extremely susceptible to chipping, especially when stacked together like that.
Does anyone see any reason "Not" to use a 7 1/2 inch blade on a 10" tablesaw? If not I will continue using them, at least until I get time to get mine sharpened.....Donny
the small diameter blades are very useful when cutting the initial slot in a zero-clearance insert: no dangerous lowering the uncut insert onto a spinning blade. Also, when using reclaimed lumber the possibility of hidden nails is ever present so the low cost of these blades is an advantage. I have been using bulk pack blades for years on my table saws and a few hang by the saw at all times. For high end work they are not acceptable but serve well for the majority o fmy work.
I'm not sure how or if this effects the cut in a noticable manner but a 7 1/2" blade turning at the same RPM will be traveling approximately 25% slower at the cutting edge than a 10" blade. (I'm assuming the pulley is not being changed out when switching between these two blades.)
