What customers say about "Key Specs"
Bosch 11255VSR D-Handle BULLDOG Xtreme Rotary Hammer
  • I bought this because I had a large kitchen and hallway ceramic floor I need to demo. It did what it was supposed to do. Made my a job I was dreading turn into a rather easy day.
  • I purchased this to aid me in my renovations and I wasn't dissapointed. This hammer drill performed great and made short work of drilling into concrete.
  • I bought this in a pinch, and I intended to break it before my job was complete.... 4 12000ft floors using this to hammer up tile, drill for conduit, and yes it was pushed hard enough that i had to go get insulated gloves due to the heat.
  • I highly reccomend this hammer drill to anyone who needs a reliable strong Badass Bulldog..
  • This is a really useful tool for renovations that I can use not only for drilling holes but also chipping concrete in small areas.

What customers say about "Features"
Bosch 11255VSR D-Handle BULLDOG Xtreme Rotary Hammer
  • I used a SDS plus 1/2" long drill bit and drilled every 1/2" along the 25ft wall and then came back again horizontally to create a breaking point.
  • The drill has loads of power and vibration is much less than other brands I have tried. Great product, I would buy it again.
  • The Bosch has more power and endurance and the D handle is more confortable :you have a better control when you are using a chisel.I would recommand this tool to any serious DIY.
  • Loved the variety of settings. Drill, hammer drill, or just hammer. Allowed me to buy the SDS drill chuck so I could use this with my hole saws or larger gauge wood and metal drills. Fantastic product with tons of power.
  • The chisel in hammer mode chipped away the rough concrete and again with ease. Very impressed with the hammer drill part that i could drill hole with the Bosch drill bit with no effort on my part and straight holes too.
