SL10 is aligned to the hexagon base on two edges, SL8 is aligned to two vertices.

If you mean S8 and S10, the hex slots look okay; it's the flathead drivers that are out of alignment to me.

That is absolutely useless, and should be returned immediately.

Very manipulative post.

You make it look like SL10 would be great, and SL8 would be at fault. But you could also have placed the SL8 to be perfectly vertical, then things would not look that clear cut any more!

Justice for SL8!!!

It seems intentional that they are aligned differently so you can identify them?

I'd take it back, I wouldn't be able to handle that. It's making me itch.

Wow, this is so mild. Well done.

The base of the flatheads are hexagonal.

They are. I agree.

Edit: I see that we're agreeing on the same thing but earlier I was coming from a different angle (pun slightly intended).

Nothing to see here. Move along.

One is for the 30° and the other for the 60° flat heads

This is an explanation I can live with.

No one refute it, please.

Two slotted screw hexagonal bit ratchet drivers were walking down the street. "hot enough for you?" said the first. "aaaa a talking slotted screw hexagonal bit ratchet driver" said the second

I'm sorry.

SL10 is a wider bit than SL8. It's oriented point to point on the 1/4 hex because that dimension is longer than flat-to-flat. Not sure why SL8 is the way it is, it could be oriented point-to-point or flat-to-flat and still be in spec either way.

Just take it out and turn it a little bit so it sits flush with the other?

It can only rotate in 60 degrees increments because hexagon, but the offset between them is 30 degrees

The Chinese worker producing these bits was a bit inattentive at the end of his 14h shift. Cut him some slack!

My guess is the SL10 is wide enough that it needs the extra space available point to point, and as such is the only one that gets precision placement during machining.

I don't think I've seen a how it's made for driver bits. Would be interesting to know what special steps are needed.

Hexagonal material is fed through a die and held in place while grinding wheels push in the hollows in each face, generally simultaneously. The tip is cut off and sent to another process to finish the back and deburr.

The alignment of the head is intentional on both parts. Generally you want the flats to continue all the way up the side. Particularly wide flats have to be aligned diagonally.

Ohhh right, would be good to have seen two positions, surely the one to the right isn't quite as bad as this

ahem actually, SL8 is aligned to faces. SL10 is aligned to both vertices and edges. The vertex is the pinpoint of a corner

Fair. My use of "aligned" was vague.

Finally something that is truly MILDLY infuriating. Upvote!
