Boride CS-HD Stone Silicon Carbide For Harder Materials 1/4 x 1/4 x 6" x 320G
A medium-hard green silicon carbide stone that works well on hardened moulds up to about 62 Rc. Silicon carbide being harder and sharper than the aluminium oxide stones, is particularly suitable for low tensile materials such as aluminium, cast iron and bronze.
