A range of cryogenic HSS parting tools of the standard diamond and beading/parting designs, all with double bevelled cutting edges. The standard ones are rectangular in section and 1/2" deep; the diamond ones are relieved on the sides to reduce jamming in the cut whilst the beading and parting versions are square in section to allow for easier access around beads and other small details. Handle lengths are 8.1/2".-bg
