Here is a vintage set of Irwin Auger Bits marked stock no DM.

There are 13 bits in the set, however there are 2 bits numbered 16. The other 11 bits are numbered 4-14. I think one of the 16s is a duplicate from a different set and the original 15 is missing.

The bits have rust on them and will need a good polish and sharpening.

The box is worn and has some rust on the metal parts. The box hinge is working but appears to have been repaired. The front clasps do not have the clasp part to keep the box closed.

The booklet is in good condition but does have some minor wear and stains.

Please review all photos and reach out with any questions.
