I've even been told that redimix concrete in the identical package from the same manufacturer is not as good at HD. Really?
I'm not sure it's true and I don't know how to prove it.
while not redimix, I used to work for a company that made quikrete. It is a franchise, I did not work for "quikrete" but for a company that made that, spec-mix, and c-cure... 3 different franchises. While there were differences in quality control between the brands (c-cure was very picky and had high standards) quikrete was the same no matter who we sold it to, whether it be HD, Lowes, Ace, or a contractor supply.
I don't think tools differ from store to store, though I see it being possible. I know it's a little different but I now work at a place that makes boxes. Some customers are pickier than others and the operators need to be aware of that and adjust what they will let "slide." The same could be done with tools, though I doubt it. The more I look into tools, the more confusing it becomes. Just because someone puts their name on something doesn't mean they manufacture it. "western forge" makes a lot of tools for craftsman, s-k has been bought out countless times and is now owned by Ideal who is still manufacturing their tools here for now. Snap-on, Mac, Matco sells a lot of "re-badged" tools from other manufacturers. They put their name on them and sell them for more money, but also back them with their warranties. Matco is actually owned by danaher tool group, who also also makes armstrong if I remember correctly. Many snap-on air tools are made by Sioux. Look up Apex tool group to see how many companies they own.
I like ridgid power tools, but I don't think I will buy them anymore because if you dig through all of the layers of ownership they are actually owned by a chinese company. Same can be said for Milwaukee I believe. Milwaukee makes awesome tools, but are made overseas (the sawzall is "assembled in USA"). Same goes for just about all power tools. Dewalts are mostly made in Mexico which is slightly better. Metabo is mostly made in Germany.
