My only complaint is that there are not enough stars with which to rate this product 5 stars are woefully inadequate

I used to agonize for hours with my other hammer drill trying to get through pre fab concrete walls

This drill does not allow me actually do any drilling

As soon as i start medium pressure on trigger with the most minimal of force on the wall the drill completes the holewithin 5 second for a 1 inch hole it also makes about 14 the noise of my old drill

Does a good job but i find that it needed greasing quite early and liquified grease leaked out from the chuck after only a couple hours of use

Found that other users had similar experiences so it looks like this is inherent in this model

I tried to brake a rock to install fence post but 30 minutes of work start leaking oil not sure if this is normal due to heat friction

I might have been using the wrong equipment
