Bosch 11224VSRKR 7/8-inch SDS Rotary Hammer

I have been using this hammer drill for over 6 years and it has never let me down. Has the attachment to use as a chisel, this works great for small jobs.

Bought this at the local Big Orange Retail Giant, cuz I needed it tonight. It chews up 35 yr old stucco very nicely, and much faster than a bricklayers hammer. Putting in new windows and eventually going to cut a weep screed opening across a 75 ft expanse so I wanted a tool that was fast enough and yet not too heavy for use on a ladder.

I bought this tool to remove tile in my shower. For a couple hours, it worked fantastic on the hammer function. But then it just stopped hammering. The chisel would vibrate mildly, but not enough to do any good. After moving it around at different angles and letting it run, it would occasionally start hammering again, but not for long, and it's back in the mild vibration mode. It's totally useless for the hammer function now (which was what I bought it for), and I've gotten only about two hours worth of use out of it. I'll return it tomorrow, and I'll probably upgrade to the next model up in hopes that it lasts a bit longer.

Bosch 11224VSR 7/8" SDS Rotary Hammer This drill made drilling 22, 3/4"X21/2" holes in a concrete slab like I was drilling in wood. The vibration was nothing compared to my Milwaukee. This one is a keeper.

Whoa! I'm normally a Bosch tool fan - gots lots of 'em. This brand new one, however, decided to give me three 3/8" x 4" pilot holes in cured concrete, then two 5/8" holes, smoked the motor, and quit on me. All the appropriate precautions (water-cooled bit, moderate pressure, etc.) could not keep this Humpty-Dumpty together. Really disappointing. I pinged Bosch to see what they are willing to do about it since it's over one year old and out of warranty. Will it be the end of my love affair with Bosch tools???
