You talking about the wedge bolt with a sleeve type, or the lead caulk-in type?

The first we usually back the nut to the end and just smack with a hammer. The second I can't imagine using a SDS drill to set.

No, they are a slick system, even over loaded small anchors never pull. :thumbup:

Its basically a sds bit with a cone on the end. Set the drill to hammer and it doesnt muck up the head of the anchor. Same thing as using the drill bit on hammer just faster and more better.

The cone fits into the anchor,
The anchor drills into the concrete.
You drill the hole.
Put the redhead in the end of the anchor.
Drive the anchor with the hammer only mode of the tool
Snap off the anchor drive part whole it's in the tool.
Install all thread.
They are about .50 each but worth 10x that when installed.
I think it might be a Hilti product.
Haven't used them in over 25 years.

I have not seen or used these "Red Head" self drilling anchors in many years. Are they still manufactured? They were a really good anchoring system. If installed properly, I don't remember ever seeing one fail. Only using a ball peen hammer to set these anchors will usually not work well enough to prevent pullout.

A 3 lb drilling hammer seems to do the trick.

Here is a link to Hilti

Just looking at it if you knew someone that had a lathe you could get a slick rod from Fastenal and have them drill the end back and have the same thing. I think it would be better to have a seperate handtool than changing bits. but that is just me.
By the was in my 40 years + years being around construction I have never seen a wedge anchor setting tool.
What we did is back nut off the anchor until it was flush with the top of the anchor and drive it in.
If we were working with strut we would screw the anchor on to a allthread rod(using a rod coupeling) leaving the nut on the anchor and drive it in that way
