They are new and in their original clear and orange plastic sleeves. PROBLEM: I do not know what they are or what to call them. This number/letter sequence is etched on one of the shafts: Hilti KM 36 606483B6.
I called Hilti and the woman I spoke to did not have a clue.
BTW, my DH thought they were concrete gouges but I could not find listing with that name.
