Irwin Boring Machine Auger Bit 1" Extra Long
This is a brand new old stock Irwin 1" boring machine auger bit with the 1/2" shank size. It is 14.5" long overall and the shank is about 1 3/4" long. These are very good drills, as Irwin was in business for about 100 years, using their original patented spiral design throughout those years in business. Top quality! The price above is for one auger bit like the bits shown in the picture.
