This is a GREAT price for a Hammer Drill. Cheaper than even cheapo HF ones. Good for cinder blocks, but when doing concrete I often find hammer drills just aren't up to the task.
And often times it's not the drill's fault, but the bits that it takes.
For concrete jobs I much prefer a rotary hammer for speed and power.
I got HF el cheapo rotary hammer, and it's actually been really really good to me....Never going back t hammer drills...
