Criterion Boring Head 3/4 Bore Capacity 3/4 Round Shank for Machinist J379

  

Note: J-379 is my inventory # only. Here is a good-working Criterion boring head with a 3/4" round shank and a 3/4" bore capacity. Comes with the Allen key for fine adjusting. No owner engravings on it, just a few usage marks here and there. This one doesn't have a model # marked on it.
