Same! Don't remember the size, but it was not the largest, the 2nd to largest, I think. Either way - no bueno.

Remembering a prior Bosch bit set in a hexagon-shaped box that I bought which looked promising, but all the bits were crappy and broke easily--as if made from pot metal!

Bosch seems to have two quality tiers: sets like these, and other smaller sets that come in their "Custom Case System" line, with much higher quality bits.
All of those that I've bought (mostly from Lowe's on closeout) have been great!

Is this a good deal for the drill bits alone? I have plenty of driving bits already.

With bits, usually, you get what you pay for. I assume this is on par with the Ryobi equivalent.

Bits work in a pinch, but don't expect hardened steel on these. They break on any hard jobs. The screw driver is also handy since it ratchets and isn't super bulky like some of the other ratcheting drivers I've owned. Overall, decent set for the price.

Can the drill bits be used with an impact? Can't tell by any of the pictures.

The drill bits are junk, literally broke or wore out after using them for minimal use. They are on clearance for a reason. Stay away
