saw blades
Looking through catalogs for saw blades to cut stone I find they almost
all look alike and are claimed to be great, but prices vary quite a
bit. What points do I look for in deciding on a blade? Or do I just
assume I get what I pay for all the time? Also, what determines if a
blade can be used wet or dry, and how can I tell by looking at it? It
makes intuitive sense that a dry blade can be used wet, but not vice
versa, and that using a dry one wet will make it last longer. Is this
true? Using water to cool and lubricate a blade and also reduce dust
seems a good idea. Why use dry blades then, maybe in instances where
water is not an option? Now to go figure out why my reactions work one
day and not the next for no apparent reason...
