SBD and TTI each have various tiers of tool offerings, and while they may share outward physical design aspects, they are pretty clearly stratified when it comes to the parts inside. Using B&D vs DeWalt as the example here, you'll typically find the following on the DeWalt part over something that might look very similar from B&D: * Better quality housing materials (better grade plastics, more glass fiber reinforcement, etc) * Better motor (higher power, more efficient) * Upgraded electronics (soft-start, closed-loop speed control, etc) * Higher quality metal bits (better/more expensive designs, better quality materials, better machining) Whether or not these differences are worth the cost delta for each tool and for each tool user is up to the user. Check through some tool teardowns and you'll see what's happening here. Typically it's not the exact same tool from the same factory line with a new label.
