3 Piece Pneumatic Air Hammer Chipping Chisel Spike Bits .680" Round Collar. These are all New/Unused, but have some minor surface rust from moisture getting on them. Not a big deal at all, and does not affect operation. 16 tooth chipping bit part number is BHI-680RC. THE flat blade chisel is C6812RC. I did not see a number on the spike. Great deal for these!
