I have a collection of been used very little hole saws as follows: 2 7/8", 3", 3 1/2" (2) 4 1/8", 4 1/2", 4 3/4" & an arbor bit, bits are nested in a very neat screw type heavy plastic container. If you were blind folded you would have a tough time telling the difference between new and these hole saws. Call Tux @ 651 7zero7 6920 Thanks
