I too bought one of the HF rotary hammer on sale for about 65.00. Works
like a champ. For the price can't be beat. I've used the hammer mode
several times to chip out slabs for plumbing moves.

Some of you asked so after using the unit this afternoon I wrote a little
review. Hope you all find it useful.

The 3/4" 3/4hp SPI Chicago Electrics Industrial Rotary Hammer #02957
normally 69.99

I purchased this today at my local Harbor Freight. It comes with chisels and
bits. A chuck to allow regualr drill bits, extra motor bushings, depth gauge
and even a dust cover for working overhead. It comes with a nice case like
you would see used by makita, though the plastic is a little thinner. This
case will come in real handy as it holds the accesories and extra bits as
well. I was imediattly very impressed with the unit.
It weighs 9 pounds and is a pretty big unit. It is grey and has a large
pistol grip. I also purchased a 6 pack of chinese masonary bits with sizes
up to 3/4".
I had a problem right out o the box. The selector for drill, drill/hammer
and hammer would not budge. I played with it and checked the manual looking
for something that may have been blocking it. Finaly after trying everything
I went ahead and did what you supposedly should not be doing and slowing
allowed the drill to rotate while trying to move selctor. WOOHOO! success.
Easily slid into new position and works flawlessly now. It felt like it
engaged while rotating and ther was no binding or anyhting.

I was drilling 3/4" holes in my drive way. I can only say I wish I had tried
using my 3/8ths, and a hammer/drill before trying this. I could feel the
unit going deeper as it chewed it way thru. In less then a minute I had
bored thru 4" of concrete. I did wait a few minutes for the drill to cool
down between holes even though it never even got warm (and to give my arms a
breather). That is just something I have learned to do with any electrical
motors especialy import ones. I did 25 holes in a row like this and there
was no problem. When you hit a stone you can really feel the hammer action.
You can really put some muscle behind this unit with little effect on the
speed.

I give this unit a thumbs up and with a 29.95 sale price I'm more then
pleased.
