Premium Ruby Ceramic Grind Rocks
- 5" Outside Diameter
- 1/2" i.d.
- 3/8" Thick
The Ruby grind rock is a bit harder than the blue ceramic we offer. Both are performance wheels and come down to a matter of personal preference.
Premium ceramic grind rocks offer superior grinding performance over conventional grind rocks. They grind cooler and offer extensive grinding life. Ceramic grind rocks only require a light tapping with a shaping stone to knock away built up grinding residue and therefore even moderate shaping is unecessary and will reduce the life of this performance rock.
