Hi guys,
I picked up this carbide grinder last week. As a newbie, please forgive my ignorance.

I notice how "regular" grinders have eye shields, yet carbide grinders do not.

Why is that?

Thanks,
Susan

If the grinder has diamond wheels, there is no abrasive or grindings flying around, but, of course, eye protection is always advised.
 
Nice grinder !

Best guess it's because the wheels are well shielded and grinding carbide does not throw sparks like grinding a chunk of iron does.
 
To save you from having to take them off and Keep price down. :D Diamond wheels are solid so no chances of exploding. They are covered to some degree but your right theirs still a danger. What isn’t dangerous in the shop? :eagerness:
 
One might consider the hazard of breathing metals dust when grinding carbide material, A person can be exposed to cadmium, chromium, cobalt
and nickel quite unknowingly. The metal dust is invisible and quite harmful. Chromium-6 is another concern while grinding and is a known carcinogen.
Eye protection is prudent but lung protection demands consideration too.

That's why there is a coolant cup that goes with carbide grinders.

I happen to have an extra Baldor water cup :) .
Since we are talking about carbide tool grinders, I noticed that in Baldor's brochures, and stock pics, the water cup has a brass tube coming out of it, yet, for all the carbide grinders, Baldor only lists a plain quenching pot under "parts," and they don't offer any cup with a tube coming out of it. Is the tube supposed to drip coolant onto the grinding wheel or is it supposed to drip water to keep airborne dust to a minimum? If anyone knows, please enlighten me / us :)

It kills both birds with one stone; dust and heat the cup can be easily tapped for 1/8" pipe thread, and a needle valve with 1/8 PT on one end and 1/4" compression tube fitting and a piece of 1/4" copper tube a few inches long completes the job.
