I'm trying to understand the significance of the "QZ" designation in some model numbers. For instance, I noticed that the drill bit DT6680QZ appears to be identical to DT6680-XJ. I suspect the "XJ" might just indicate it's a bare tool. But why do some retailers include "QZ" while others leave it out? Is there an actual difference?

The "QZ" usually indicates some kind of market or packaging variation. So, even if it looks the same, differences might be in the packaging or languages included in the product. It doesn't change the tool itself really.
From what I understand, the 'XJ' in DT6680-XJ is confirming it's a bare tool. So yeah, I'm guessing "QZ" might not have much impact on the tool's performance or features, just some regional differences on how it's marketed.
Originally, the "QZ" used to represent battery capacities, like a 4Ah or 15Ah. So, in some contexts, it still refers to batteries, but with drill bits, it seems the rules might be different. If you're seeing DT6680QZ vs. DT6680, the item itself should typically be the same.
