Milwaukee 2912 Vs 2915 (M18FH vs M18FHP)
HTML-код
- Опубликовано: 14 авг 2024
- Milwaukee M18 Fuel SDS plus rotary hammers with many different names (thanks guys) are very similar looking but boy do they hit different! Here we put the 2 main hammers in the red SDS+ lineup to the test: the 1" vs the 1-1/8" or as we say here, 26mm vs the 28mm hammers.
Called the 2912, the M18FH or M18ONEFH and the, the inch drill is a real nice hammer.
But what about its big brother the 2915, M18FPH, or M18ONEFHP? let's find out!
Here we put them both to the test, seeing how they drill in concrete, wood, and also how good are they at chipping.
Which Milwaukee SDS hammer drill is the best? We find out.

My 2915 went faulty after a year of owning it (only used it about a dozen or so times, mainly for tapcons, a few anchor bolts & light chipping duty). After having it in storage for about two months (worked fine last time used) the red light would now instantly flash as soon as the battery was inserted. While it was working I loved it, so much so that I ended up selling my Bosch GBH 18V-26 SDS plus rotary hammer drill after the first time using the 2915. I ended up buying the Milawukee M18 D handle 2916 to replace the now faulty 2915 and so far I like it a lot.
The 2916 is the biggest D handle on the market so far, what do you usually use yours for? I think it's a great idea to make big d handles for the ease of chipping floors etc that shape gives you
@@BoltahDownunder I am an electrician by trade, so I use the 2916 to drill holes for different mounting anchors, tapcons, chipping raceway channels into block or concrete walls, etc. I had to use it last weekend to drill 5/8" & 7/8" holes through 16" thick precast walls using Milwaukee 18" long 5/8" & 7/8" carbide-tipped SDS Plus bits which made easy work of the task once I predrilled pilot holes using a Milwaukee 18" long 3/8" SDS Plus carbide-tipped pilot bit. I use the Milwaukee M18 12Ah batteries to be able to carry out these heavier duty tasks which a single battery ended up lasting me the entire day. I also have the Milwaukee vacuum attachment for the 2916 which comes in handy when drilling overhead holes for anchors into ceilings.
Can you add a "impacts per rev" column. Milwaukee has a very large spread from 3.6-7.3 ipr. Most other brands stay at 4-5 ipr.
I found a treasure today and its your channel , i have seek so much and never found a comparaisom between thoses 2 sds thanks for that 🤟🤟
And I thought I had enough Milwaukee Rotary Hammers.
Enough? Not sure I follow... But the good news is you should only need the big one here. While the new inch drill is much more powerful than the one you have, it is also much bigger & heavier so I wouldn't recommend it for climbing stuff
@BoltahDownunder oh I already have the 2912. I have several of the 2712s that I have put in thousands of holes with.
I guess there's still the 2915 & the d-handle version! Plus they have to be releasing some new compact hammers soon, their current ones are ancient
Looks very powerful. Only other tool in that class is the Makita HR008g, but it's 3.9J vs 4.9J and lower IPM, so likely slower. I think if Bosch had changed the gearing on it's SDS+ to get more RPM/IPM, then it could match them.
Edit: just noticed that you haven't tested the DCH417 yet. That could be close
Who tf knows what Bosch is doing nowadays 😮💨
But yes Milwaukee has done a great job of getting high impact force at higher speeds than the others. I still think their claim 4.9J is a stretch, but that hammer really brings the goods so I'll give it to them for now
А где тест с макитой 008,почему про нее нигде нет видео сравнений в том числе и на Вашем канале?А так благодарю за отлично проделанную работу и Ваш труд,но я отдаю предпочтение только макита!!!@@BoltahDownunder
Great video mate. Really helpful. Cheers.
This was the comparison I was wondering about. Thanks for the video. The 2915-20 was going for $398 usd a couple of weeks ago. It was a combo deal, including their fuel angle grinder. The sds usually retails for $449 and the grinder at $199. If it ever gets that low again, I'm definitely picking her up.
you can get the 2912 for $203 and the bigger 2915 for 288 USD at HD when you return the grinder. I may bite, just a homeowner tho, and i already have a corded hammer drill and a jackhammer, but i'm a sucker for nice tools haha. If I had a project where i knew i could use it i'd buy it now. Do you think they'll come out with something much better in a few years is the question i ask myself...
@patrickpk6299 It won't be for a while. These 2 are their top-tier compacts for now. If you can afford it, why not. I'm like you. I've spent quite a bit on power tools cause I like them. I have a project in mind when the kids move out. Going to redo the basement. The sds hammer will come in handy for sure
Excellent review. Subscribed.
Will check out some other vids for sure.
«One» usually means One key in milwaukee naming lingo I’m pretty sure. They tend to release a tool without it first and a version with it as well later.
In Czech Republic cheapest version is FHX for 314€ and Standart FH is around 420€
Any experience testing with the sds max 1-3/4 2718? Love your videos 😁
What exactly is the relationship between rpm/bpm and impact force for rotary hammers? I don't quite understand them, shouldn't the one with the most force per blow regardless of bpm/rpm drill/chip be the fastest?
Fastest rotohammer will usually be the one with highest joules per minute (joules × BPM). 4J × 5000BPM = 20kJ/min and would have similar speed to 5J × 4000BPM. The 4J @ 5000 would be slightly faster on smaller holes and the 5J would be faster on larger holes. Smaller holes work better with lower joules, higher BPM and high RPM to clear dust out faster. Large holes need high joules or there wont be enough energy to break rock.
Impact force is for one blow, so higher BPM means more blows per minute. If 2 hammers have the same impact force but different BPM, the higher BPM will remove material faster.
RPM & BPM will vary with how far you're pulling the trigger, so for a tool running at full vs half speed you'll get less impact force at running the tool at half speed.
Think if you're swinging a hammer fast vs slow, the faster swing hits harder. So if you drive the tool at say half it's speed, you get half the RPM & BPM, but also half the impact force per blow, so it won't drill half as fast but 25% (or less).
Running a hammer faster means more blows per minute and also harder blows.
Sorry does that help?
@@toolscientist thanks that helped
@@BoltahDownunder yeah that helped a little bit. I do more demo than drilling so it's just strange to see my bigger hitting hammers on your list do worse in terms of drilling speed with so much force behind them. I appreciate your channel, I think rotohammers are the coolest power tool out there.
Ohh right. Yes it's a bit odd but like TS said, the hole size matters. You do see smaller hammers drilling faster in smaller holes sometimes. But when you're drilling big holes only big impact force will do. Like the big Bosch I mentioned in this video (34CF), it's slower than many at 12mm but the fastest at 26mm. Even with 5.8J impact, the bit can only dig so deep per blow with a 12mm
How come you think that quick change chucks are useless? Is it not good to be able to use standard drill bits.
They make a big, heavy, expensive tool more so. They're a weak point that could break, a leftover from the days when combi drills weren't so good. But now I have a small Milwaukee combi drill that's got more torque than any rotary hammer and a gearbox that makes it way better for normal drilling than any rotary hammer. If all you have is a rotary hammer then yes it's good to have normal drilling ability, but you can also get adaptors rather than change the chuck
Are the battery powered rotary hammer drills better than the corded counterparts.
surprised of your battery results . that the forge didn't show improvement . was it due to being brand new or does the hammer just not use a big load .
I didn't test the forge, that was just an ad. But if there's almost no difference btn a 5ah & 8ah HO, then no this tool doesn't draw enough current to benefit from HO or forge.
There may be situations when it will, eg if you're drilling something really big, and have a dust extractor with its own motor, but in general I wouldn't think forge improve this tool's performance
@@BoltahDownunder got it .sounds exactly right .thankyou for reply
I need to really understand this,are these rotary hammer drills meant only for concrete only or they can still be used for other materials like hard steel and metals.What does the SDS means,I need to understand these things to know which direction I need to go.Thanks.
No, SDS drills aren't really suitable for metal. They can get through rebar with a suitable bit, but they are for concrete & stone. SDS is the chuck/bit type. 10mm with slots. These drills usually have a rotation only mode and can hold normal bits with an adapter, but you don't want to buy one of these for drilling metal
Do you think the new forge batteries will give these two drills a boost?
Nope. They only help if the tool is slowing down under load, which doesn't really happen with hammers compared to eg circ saws or grinders.
@BoltahDownunder might help with really long holes (depth/diameter > 20). Otherwise it's as you say and there's very little torque on the motor.
