Can someone tell me what the difference is between Model 2780-21 and Model 2780-22 other than $100?

Can someone tell me what the difference is between Model 2780-21 and Model 2780-22 other than $100?
Asked by: Rennat
2780-21 comes with 1 battery and 2780-22 comes with 2 batteries. That's why you see $100 difference. Picture of both products show 1 vs 2 batteries.

Can I use 5.0 Ah battery for this grinder

Asked by: Toli
Yes. Ah or Amp Hours only defines the amount of energy stored by the battery more amp hours means longer run time.

I used it with a grinding cup to shape stones. Good balance with a large 5hr battery. Little bit heavy with one hand operation, but it has plenty power for its size. It did the job for me.

Rated 5 out of 5 by from Quality grinder that cuts the cord Bought this grinder after purchasing some other Milwaukee Fuel tools for some metal work. I've used this grinder exclusively on metal grinding off mill scale and welding slag and with a cutoff wheel for expanded metal. Though it doesn't spin quite as fast a milwaukee's corded grinder, it spins plenty fast enough to get any job done. The best part is the power, no matter how hard I push this grinder in, it just keeps going! ...something I can't say for some corded counterparts. The downside, this grinder does go through the batteries a bit faster than I would like, so I would buy the kit with just one battery and spend the other $100 on the 5aH battery instead... Considering the abuse I put this tool through though, I really can't expect much more out of it.

I would recommend using the 5.0ah battery at the absolute minimum, if you have a 9.0ah battery...Even better!!!
