Don't know but Ms. bought me Rockwell's 3Rill for birthday present, along
with lifetime battery warrantee. the small handle holding the battery and
'light weight' makes this tool incredibly useful. Get the FULL set that
comes with it, too. PS: with two batteries and quick charge have NEVER
been left waiting for power.

I bought this one and love it. Not the full kit, as I have plenty of
bits, etc.

The batteries have a circuit that prevents a deep discharge.

My 5-piece Bosch 18V set has 3 dead batteries that would cost ~$150 to
have fixed, so I plan to sell the tools and buy a corded Jig saw.
