Hi: I used to work with abalone and yes it can make you very
sick…the best way to deal with it is under running water…a flex
shat and and grinding wheels ( mizzey heatless) diamond and carbide
will work well, waterproof sanding disc will work well also, object
is to not breath the dust…and I suggest using a mask when working in
water flow…a little messy but it is better than suction…
