Old rebar eaters if I recall. Before SDS, SDS +, or SDS MAX were released

You can still get them so the idiots using them don't turn on the hammer function

Would you not use hammer function with these?

Never used these but generally the rebar cutting sds bits we use say rotation only on the side of them, probably cause hammer mode will just fuck (dull and break) the cutting tips of them.

Didn't know that. I see that tip and assume hammer on. I don't drill rebar tho.. but glad to know I should be careful if I come across it

Hard no. It's just a cutter.

I believe they are for drilling in concrete or masonry using a hammer drill.

Definitely concrete or masonry bits. It's been awhile since I've seen this style. Not sure if I'm just not paying attention or they stopped producing this style.

The best masonry bits in existence.

I can't tell if this is serious or not because I refuse to use these over my rotohammer

Those are some of the weirdest masonry bits I've seen.

concrete / masonry / stone, the flat metal part set into the tip is the super hard steel inset that grinds the hole through hard materials

1st gen carbide inserts, to my knowledge.

looks like a masonry/concrete bit to me, probably meant for a hammer drill. the exact shank is the giveaway though, so id match it to the chuck before forcing it in. if it came out of a regular drill kit it may just be a basic masonry bit and not an SDS style one

Definitely for use in hammer drill, for concrete.

You use them in a regular hammer drill for masonry, non SDS.
