Observation...Cheap router Bits

I may have an exact match...

..to that set. Same aluminum case, all 1/2" with sort of thin carbide and stubby shanks.

But, the set was something like $45 new (less than a dollar per bit) and every single one that I've used has worked fine. I don't do a lot of routering, but once in a great while, I need something like a roundover or whatever and it's been fantastic to have on hand and not waste time or money chasing expensive bits for a single use).

More likely...

Whoever spec'd the shaft length in the Chinese factory had no idea what an appropriate length really was.

From what I've seen, the cheapness comes from cheap carbide and probably mild steel bodies and shanks, as well as rapid production and no QA involved. Boss in a woodshop I worked for used to buy cheap bits from Woodline or some such outfit. Some were just fine, but I got one once that was so out of balance that one of the two blades never even touched the wood. Never would have passed QA at a factory that had it.

I have only used about four of these bits and those have been fine. They cut well with no undue vibration. I will not be surprised if the bearings fail, I have seen that on other bits. OTOH, I have a tendency to get "sets" and then not use them to avoid breaking up the set. On this one I decided to use the bits as needed. My plan is that if I wear out a bit because it proves to be useful I will buy a better quality replacement.
