Criterion CRI-TWIN-200BD CRI-TWIN-280 Twin Rough Boring Head 7/8 Straight Shank

  
Criterion CRI-TWIN-200BD CRI-TWIN-280 Twin Rough Boring Head 7/8 Straight Shank. Not much to say, moves and locks up as it should. Has standard length arms on it, and includes one insert and screw as shown. Insert pocket on the remaining side looks good. PLEASE NOTE: that one of the locking screws for one of the arms appears to have the head broken off. This doesn't seem to actually affect anything as the head can still be locked, but it's worth mentioning.
