Will be chiseling grout out from around an industrial compressor foundation pad roughly 8'Lx10'Wx2-3" wide. The jackhammer is a bit big and bulky for this so a hammer drill with hammer only mode seems like a better choice. Any recommendations?
My partner and I occasionally have to fasten tapcons and concrete anchors in concrete subfloors. We typically use an older corded Rigid Hammer Drill (not rotary hammer) with longer Bosch 3/16 SDS bits. We also occasionally drill holes for 1/2” concrete anchors or under. The Rigid is about 10 years old and we are looking to replace.
We have a Milwaukee M18 drill and want to keep with this system since we have invested in a number of batteries for it.
We are considering replacing the Rigid with an M18 Rotary Hammer for the purpose of drilling into concrete. I’m leaning towards the 1” vs the 1 1/8”. For the use cases mentioned above, will the 1” be sufficient?
I am trying to drill holes into red brick for several camera and also water hose. I have a Rotary Hammer Drill, with a new Milwaukee 1/4” masonry carbide bit. Drill in hammer mode instantaneously cracked the brick into several pieces, and drill in normal mode with water to cool it down only get me less than half an inch after couple of minutes.
What else I can do to drill into this?
Edit: Brick : ACME Brick, ASTM Grade SW
Using battery powered rotary hammers and I'm not able to get a rhythm with how often the battery dies. Also every 30 mi s I have to stop at let it cool to stop it from overheating(grease starts to bleed through drill bit).
My question is would the corded tool more robust and solve both issues?
I can’t find hardly any reviews of 2713-20 (Older d handle version), and I’m wondering if it’s worth the extra $ for the newer 2912 version. Anyone know the differences?
Main uses are tile demo/thinset removal in smaller areas (100-200sqft) in my house, other homeowner projects, and to look badass. Could i live without it? Yes, but i want one.
Looking to purchase a rotary hammer drill for various jobs at home and mainly for work, but don't really know what brands are good and what's complete junk.
Thanks a bunch.
I’m planning to pick up a rotary hammer at some point this year so that I can mount fixtures in my basement. I’ve never used a rotary hammer before, but I’ve used hammer drills and air hammers. A 1” capacity should be fine for my needs, and I won’t be using it professionally so it won’t see heavy use.
I see that there are two different body styles: models like the Bosch 11255 have a long body, while others (e.g. Makita HR2811) have a short body.
I guess the motor is on a bevel gear in the short body ones, and the short body seems to being a bit of a price increase.
I can see how the short body could be better:
- when using two handed, supporting hand doesn’t have to reach out as far
- less likely to have clearance issues in tight spaces
I’m curious which way I should go. Are the long body models more reliable because of the lack of a bevel gear? Do the short body units have better impact power because the motor is out of the way of the impact piston?
If you’ve used both, which do you prefer?
Thank you!
Over the next ~5 years I need to
a) remove a bunch of mortar from my fieldstone foundation (all loose around entire perimeter over the next few years), and
b) remove a bunch of tile and
c) break up some concrete (maybe id rent a jack hammer for this)
And d) demo a fieldstone chimney in my yard
Im thinking the Dewalt XR rotary hammer would be ideal for helping in all these tasks but it just seems like overkill for all but the last. My cordless stuff is Dewalt xr 20v.
If I do get a rotary hammer, should I go corded or cordless?
As the title says I am undecided on which should I pick. Since I am already owning 4 18V batteries from professional Bosch series I am thinking of getting cordless rotary hammer instead of classic corded hammer.
corded GBH 2-24 DFR
vs
cordless GBH 18V-26 F
Corded
^(Pros)
- ^(Can hammer for long periods of time)
- ^(Cheaper)
- ^(Lighter)
^(Cons)
- ^(Pesky cable)
- ^(Longer time for preps)
Cordless
^(Pros)
- ^(No pesky cord = speed of preparation / maneuverability)
- ^(Already have 4 batteries)
^(Cons)
- ^(More expensive)
- ^(Battery logistics nightmare for longer period hammering sessions)
- ^(Heavier)
Storms this year blew down the 30-year old fence between me and the neighbor's, and this month we finally set aside some time to fix and put up a new fence.
We cut down the old posts and set the new ones a foot or so from them to avoid having to remove old concrete, but the last terminal post we'll need to keep in the same spot due to setback bylaws and not wanting to reduce the yard area enclosed. So we rented a very heavy jack hammer for half a day to remove the concrete that was holding that post, and chipped away just 2' of it before we had to return it to Home Depot.
Main issue now is the hole too deep and tight for that jack hammer to get at the remaining 2 feet of concrete. Then it came to me that my dad had a small hand held pneumatic hammer with chisel that he used to chip out a hole in brick wall for a side door, and I figure something like that will get the job done more efficiency since it's more compact. I'm not at good terms with the old man, so I'm going to need to get my own - and also using this as an excuse to get a bigger air compressor to replace the puny 1/3 HP Mastercraft I currently have.
Then comes along my coworker who suggested I get a electric rotary drill instead....
So my question is which one will be better for this job, and keeping around the garage in general? The air hammer (with bits included) + new compressor will run about the same price as a Bosch rotary drill/hammer + separated bits. I'm leaning towards the air hammer, since I can also do some riveting with it in the future. Thoughts?
I've been going through the garage to try and get it organized and came across my Dad's old Hilti TE 17 he bought probably back in the 70s. I've never once needed a rotary hammer or hammer drill and I can only ever recall him using it once (to get in to a large concrete reinforced safe that the combination to was lost). I'm just wondering, if I ever actually found myself needing to use one of these for something, would I be better off picking up a new Milwaukee one and getting what I can for this one on eBay, or are these older ones built better and worth hanging on to?
