EY7840X is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Extremely powerful This is the best cordless hammer drill I have ever used. It is not cheap, but is phenomenal for overhead drilling, putting holes in cinderblock and cement. I have used coring bits with this drill (although way beyond rated capacity) of up to 2.5" with no troubles. 3 years of abuse and it is still going. Air piston hammer really drills fast. Unbeleivable power for a 14.4v battery. Just amazing.
