vStones plus shaping & dressing aids for stones


Stones specially formulated by Mondello in aluminum oxide & silicon carbide are designed to make your final surface conditioning finishes quicker & easier.  They allow you to maintain better shapes & smoother finishes when used right after carbide cutting & shaping is finished.  They remove carbide chatter quicker than a cartridge roll & can control your port shape, radiuses, high & low spots much easier.  Your final polishing will be much faster leaving a better, smoother final finish.  Always use our SD-240 & DS-3 to shape & smooth your stones for a better finish & longer stone life. Each stone has a brief description of where we use it in our work. Our stones are for use on cast iron & steel only.
