Re: Looking To Buy A New Hammer Drill.


If you already own batteries and it's cordless you want then go makita for sure. I was so impressed with the cordless model that I bought the matching corded model,for when I'm doing bigger holes.

I would stay away from dewalt and Milwaukee as they ain't been upto much inn the last few years.

Bosch, makita and hilti make some of the best corded drills but I wouldn't say one is better than the other.

Re: Looking To Buy A New Hammer Drill.


Since I only use corded rotary drills my vote is for a hilti model I think I have the te15 awesome drill. But if your on a budget I also have a makita, not sure of model number, that is very comparable. Probably won't last as long as hilti but half the price. Sds is the only way to go in my opinion. 3/16" - 1" holes is my range.

Not to get of topic, but from my experience, the motors in Boschís corded hammerdrills are weak. Their hammerdrills are fast and have good impact, but run hot and are prone to field winding burnouts. Both my old 4.8 and 6 Amp as well as a newer 8 Amp had this problem.
I do own a couple of different sizes of their corded SDS and spline drive rotary hammers that I really like though.
On the other side of the coin, I have a 20-year old 7.5A Makita HP2010N hammerdrill that is still working. It was always great at things like drilling 12" thick oak beams and mixing buckets of grout, but lousy for drilling into concrete because the impact is just too light.

IMO, any cordless hammerdrill will be way more versatile than a regular cordless drill and much faster when using hole saws and spade bits.
Depends on the drill, some brands offer the identical drill with and without hammer. I never use little cordless hammer drills, too slow. Sure you can put in a tapcon or two but after you use a roto you never go back.

I have an 18V Ridgid and 18V Dewalt XRP cordless hammer drills and I've used the hammer function about twice since I got them years ago.

Re: Looking To Buy A New Hammer Drill.


Not a huge fan of DW cordless but their hammer drill is 3 speed, making better in impact rate, and had a super all metal carbide insert chuck that ratchets. I use that first if I need cordless. Better than my German made older Milwaukee's HD's. I do use my corded "D" handle Makita SDS+ the most, excellent impact drill. The older corded DW HD ,I have is just OK, and the replacement model has a plastic gear box[black front] that is a pure junk tool.

Exactly, so for the minimal weight and cost difference, it makes little sense to buy the cordless drill only, because the hammerdrill can do everything the regular drill model can do and more.
If you need to use it with a hole saw in wood, then a hammerdrill is faster than using the drill only model.
They are also much faster at drilling with spade bits in hammer mode than the regular drill.
Turn off hammer mode and use your hole saws for metal, drive screws or make a hole in metal with a step drill. Switch to low gear and use your 1" X 18" nail eater or a 2-9/16" self-feed auger if needed. Itís not always the best or only way to get the job done, but itís still pretty tough to beat the hammerdrill for overall versatility. IMO, this applies to corded models as well.

Re: Looking To Buy A New Hammer Drill.


i have a Bosch 1-1/8" i bought the end of summer. great tool, makes short work of drilling thru concrete
i have used Hilit, Milwaukee, Bosch, Mikita, Hitatchi, ect.
they all work pretty good.
my co-worker had a Milwaukee. i was gonna get one, seemed like a nice drill. its been in the shop twice already now. not sure about the quaility of the "New" Milwaukee. I do have a Milwaukee cordless set and like it a lot.
use them all and see which one you like.

Don't drill a lot of concrete eh?

Big drills hit hard and turn slow, they take forever to drill small holes and snap bits...but great for big holes.

Small drills turn fast and hit less hard, good for small holes but useless for big ones.

Good point.

I use self-feeding spades so hammer doesn't help, and I find that with a sharp hole it works just as well and rock the drill a bit without hammer.

Regarding the Tapcons mentioned earlier, I have found that a hammerdrill does a better job of making the holes than an SDS hammer does for the small diameter 3/16" and 1/4" fasteners. The heavier impact of the SDS causes the long thin Tapcon drill bits to flex and bow outward elongating the holes so the anchors don’t hold as securely. The hammerdrill with its lighter impact doesn’t seem to do this as much so the anchors hold better and those little 5/32" and 3/16" drill bits also seem to last longer. This seems to hold true for conical anchor holes as well.
I have the older Dewalt DW999 18V cordless SDS hammer from about 7 or 8 years ago, that I will sometimes use with the Condrive tool, but generally only if a hammerdrill isn’t available.

What exactly is a sharp hole?

Use the Hilti kwikcon system, different bit for block and concrete. Makes life a lot easier.

If you don't want to use it then get the shortest bit you can, shorter bits flex less; for small holes use a less aggressive faster spinning drill...I use my TE2 for those sizes.

Don't get me wrong Milwaukee is the best.
And Hilti produced the first "electro pneumatic hammer drill" The TE 17, the modern hammer drill. And nothing is close to a Hilti Hammer drill, your kidding yourself if you think differently.

Re: Looking To Buy A New Hammer Drill.


After recently acquiring a Milwaukee 1/2" Combo Hammer Drill (Model 2611 if you must know)

I would never recommend buying one if you do intend to do a lot of concrete drilling, UNLESS you need to drill lots of little holes under 1/2".

If you have to drill holes over 1/2", rent or buy a proper Rotary Hammer, SDS would be my general preference.

Like some have stated with a Rotary Hammer vs. a 1/2" Hammer Drill you do risk breaking smaller bits, which is not cool either.

But the noise from a Hammer Drill just sounds like ungodly things happening to gears, which technically is how they work, but it's a painful sound, doesn't feel to hot either.

Re: Looking To Buy A New Hammer Drill.


My experience with hammerdrills versus rotary hammers is the hammerdrills tickle my hands too much, can't hardly stand it! Guess I'm maybe just ticklish. I've used the rotary for small tapcons haven't noticed any problem
