Today I’m going to review and chisel
with the Bosch Bulldog extreme model 11255VSR. “Boss Bulldog Xtreme” Arf! It’s a 1 inch SDS plus rotary hammer, and typo aside on the word “Xtreme,” nice one Bosch!
Learn to spit… Ha! Learn learn to spell and I’ll learn to speak. This tool is for the
DIYer and end contractor alike. I’m doing this review because there were
only a handful of chiselling videos on this model so I couldn’t determine if
the tool was the right tool for my job.  So today I’ll be chiseling in “Hammer” mode
using both the Bosch 1.5 inch by 10 inch wide, steel, self sharpening
chisel, model HS 145. It’s for concrete. And the 10-inch, steel, pointed chisel for
concrete, model HS1472. If you’d like to see this tool demonstrated in
drilling applications I’ll provide helpful links to drilling videos that I
watched in the information section below. Also see the information section if you’d
like to jump to any section of the video, for example, if you only want to see the
tool in action. Before we get into it let me show you what comes in
the kit. You get this nice hard shell case. There’s a lot of helpful
information on the inside cover that tells you the part numbers for drill bits and chisels. There’s of course the manual, grease cloths, and the hammer. The Bosch bulldog extreme 1 inch SDS plus rotary hammer is designed for both
drilling and light chiseling applications. While it weighs only 6.7 pounds, which is less than a real bulldog, this 8 amp puppy
impressively delivers an impact rate of 5800 BPM, and 2 foot-pounds of impact
energy. The tool has a brush motor and comes with a hammer hook for hanging the tool
(whatever!), a depth gauge. You just press the button move the depth gauge
and it locks in place. And an auxiliary handle, which swivels 360 degrees. You
simply loosen the handle grip turn and then tighten. The tool has a variable
speed control trigger, a reversing switch, and preset slip clutch. That way if
the bit binds in a hole or the tool is overloaded, the bit stops spinning,
although you might get a quick twist when the bit stops. The hammer has three modes selected using the selector dial. “Drilling Only,” for drilling wood, steel. etc. “Drilling/Hammering” used for drilling concrete, and “Hammer Only” used in light chipping work with chisels. That’s what I’ll be demonstrating. There’s also a “Various Lock” setting which is used to
conveniently choose from 36 10 degree positions so you can rotate the chisel
to a safe and comfortable angle. Before sticking a bit or chisel through the
dust shield and into the locking sleeve you need to add grease. The tool doesn’t
come with Bosh’s recommended grease which is part number one six one five
four three zero zero one zero so keep that in mind.
The recommended grease is expensive if you can find it and only comes in baby
sized tubes. Shame on you Bosch! I’m sure you can find less expensive options that
would probably work just as well though. Regarding the warranty it comes with a
one-year warranty, but what I really appreciate is the 30-day money-back
guarantee. Had I tried the tool and realized it wasn’t the right tool for
the job or it just wasn’t working for me, I could have returned it
back to the retailer within 30 days. No questions! Awesome!
But I like it too much to return it anyway. It’s mine! It’s mine! It’s mine!
It’s all mine! Regarding price. For what I consider a solid tool it’s priced fairly.
It’s available from many retailers so shop around to get the best price. In my
case I bought it at the Home Depot because they matched the sale price of another
retailer. I love that about the Home Depot. I got it for a great price.
Alright! I’m gonna put on safety glasses a dust mask and hearing protection and
show you this puppy in action. So this is a hole that I have in the concrete slab
of the basement. It’s about 2 feet by 2 feet. There was a concrete patch over it
and it was cracked and hollow-sounding so I ripped it up. It appears that
there was an old chimney here or a heating system, maybe even a brick column.
In order to put down concrete I need at least 2 inches of clearance and that
way I can use concrete as opposed to a patch to make it stronger. Let’s see how it does on the brick right here. I need to get two inches so I’ve got my work cut out for me but the Bulldog seems to be working pretty well. It also helps to make sure the chisel stays sharp. A dull chisel would make this job go a lot
slower. I’m gonna change out the chisel edge. Now these things can get
super hot so you want to make sure you’re wearing cushion gloves. You just pull the
chuck back and lift it out. Working pretty well. I think it helps that it’s nice and sharp. I feel like the chisel got dull pretty
quickly. The point cheese is working pretty well. I got my work cut out for me and I’d say
the best cordless drill under $100. It helps that it’s nice and sharp… because it’s new! I’m sweaty! It’s dirty! It’s dusty! Ugh!
Let’s wrap it up! To wrap up, even though I typically avoid tools with silly names
the Bosch bulldog Xtreme rotary hammer worked well for light chiseling of
concrete. I’ve also used it for chiseling tile, removing thin set, and cutting
blacktop when I was patching the edge of the driveway. At the end of the day any
project gets done faster when you have the right tool for the job and while
this tool worked well for me today, had the area been more than 2 feet by 2 feet,
or had I needed to break up a solid slab of concrete, I’d have definitely
preferred a more substantial, yet expensive tool like this. “OK! Say hello to
my little friend.” I even spit when I said that just like
Pacino. A more powerful tool would have worked faster and more importantly got
me away from the dangers concrete and brick dust sooner. Mansplaning? Thanks little assist. I hope this video has been helpful. If it has please do me a favor and like it, and
more importantly please subscribe, that always helps me out. And as always
thank you so much for watching!
