This is just like our VersaNotcher shaft except it has 5/8-18 threads cut right into the end of it. This DOESN’T use our removable arbors. This high quality shaft is made from domestically produced 416 stainless steel. If you prefer a fixed shaft, this is for you. This shaft has no warranty against user-caused damage. Works with 1 1/4″ and larger hole saws.
