Are angle grinders rated for continuous use?


Recommended Posts

Some years back my dad built a fuller grinding set up, which uses a Draper angle grinder mounted on an old lathe bed (the design required the handle mountings to be in line and parallel to the cutting action). I can't find anything on line about the duty cycle for that machine corded angle grinders in general. Any idea how long it would be safe to run it for continuously without burning out, how long to cool down etc?

Just run it until it gets hot Jake! You can get a pretty decent small grinder for less than £50 if it burns out. Wasted time worrying about it exceeds the cost of replacing it!

I normally treat them as consumables, but the problem is that the mounting for the grinder on the lathe bed is bolted into the handle holes, so if it dies I'll probably need to find exactly the same model, and hope they haven't changed the housing. I've got multiple fullers to do on a 34" blade, and I really don't want it to die halfway through...
