I have two boxes full of stones but I mostly use my carbide burrs:

As for the batteries. When I bought the Makita light it came with a newer style battery (I bought the light about two years after the Makita drills), the newer battery wouldn't fit (go into) my drill/screw guns. It really pissed me off that they had changed the battery design. But after looking at the battery differences I determined that I could modify the newer battery so that it would fit/work in all my Makita tools. Here you can see the old style battery on the left and the newer style on the right:

Here you can see where I used the Makita die grinder to trim down this section of the battery plastic:

After doing that minor modification the newer style battery slid into all the Makita tools I have including the Makita impact wrench. It felt so good to "stick it to the man" so that I didn't have to buy more batteries, now they all interchange.
I only paid $39.99 for the "bare" die grinder. There are many (100 percent positive rated) ebay sellers that have new tools out of the box or they get new tools at estate auctions. They turn around and sell them cheap on ebay.
