Grizzly H8305 - Internal Threading Boring Bar - 5/8" Shank, Right-hand
These boring/threading tool holders have flats which, hold the tool in a negative position. Don’t worry, the inserts we carry have more than enough rake to move chips fast and efficiently! The insert pockets are cut for a tight fit and the 60° cutter profile is fully supported. H8306 and H8307 have carbide anvils. Inserts not included.
