I love makita, It help my work more easily. ;D

First off the Hilti is over 1kilo ( about 2,2 punds ) heavier than the dewalt. Second, you can not compare J to ft-lbs imapct energy. I´m not saying that the Dewalt 36 v hammer is better than the Hilti since Hilti have a very strong name in concrete applications. But I do know that I´m very satisfied with my small 18 v DC213 dewalt at only 2,9 kilo. That machine is for most applications strong enough at only 2,9 kilo. To me that battery Hilti seems to big, after all we are talking about battery powered concrete rotary hammers and they are all regardless of brand somewhat limited when it is time for big holes or demanding chipping. When I´m going to do demanding concrete work I go to my worktruck and pick up the D25602 rotary hammmer with a cord.
And the most interesting thing, is the battery on the Hilti rotary hammer the same battery as on the 36 v hilti drill? I do not know, Just wondered but on the Dewalt I know you can swap the batterys between the rotary drill and the normal drill.
Hilti dont have 36v drill driver only WSR 36-A 36 V Cordless Reciprocating Saw 36 v Cordless Circular Saw and 36v TE 6 and 7 rotary hammmer

Yes you can.
1.9 Ft-lbs is 2.58 Joules
So Hilti is 2.6 J, essentially they are the same. In terms of runtime, Hilti will absolutely slaughter DC212/213 and DC233.
If you need cordless for hammerdrilling 12mm or bigger holes, and don’t own any 36v Dewalt tools, definitely buy Hilti.
For smaller than 12mm holes, any 18v SDS drill will do. If you use non-SDS drills, you will quickly wear out the hammer mechanism.
Yes, of course you can compare J to ft-lbs. What I meant was that you can not just show the numbers in J and ft and compare. You have to transform one of them so you compare apple to apple like you did.
Not saying that the Hilti is a bad tool, only that it is much heavier than the dewalt, thats all. ( I know Hilti makes very good tools )
I have never had the opportunity to try out the cordless Hilti, but if the runtime is so much better than in the Dewalt, what kind of battery does Hilti use? Or is it just more cells and thats why the Hilti is heavier?
I don’t know where Aprelia is getting his information, but I regularly embarrass the local Hilti reps doing head to head demo’s with the 36v sds vs theirs. Plus, their on board dust extraction unit is not remotely as good as the unit on the 36v dewalt (if you need dust extraction, if you don’t use that feature, than it wouldn’t matter).
Aprelia, what test are you doing to get those results? (not questioning you, just more curious, because we see quite the opposite around here). I have a number of very large companies that I have recently converted out of the Hilti hammers into our 36v because our runtime is significantly better, as well as our dust extraction unit is far superior.
If you don’t mind letting me know what you are doing to get those results, I would be curious to try it and possibly pass it back to the product team.

Are you testing them with 3.0 Ah battery or 3.9? Try using this http://www.hilti.com/holcom/page/module/product/prca_productdetail.jsf?lang=en&nodeId=-9769&selProdOid=8785
1/2″ bit, and see the results for yourself. No matter what you do, 2.3 Ah battery will lose to 3.9 Ah battery, even if they have higher mechanical energy transfer losses.
As for dust extraction, it’s freaking impossible to find it in retail (at least here in Nova Scotia), and if you do find it, it’s retarded expensive. It’s cheaper for me to buy it on UK eBay and ship it here than buy it locally. It’s good but it’s totally not worth the money, I can buy alternate comercial solutions for fraction of the price.
I will try to ask hilti for a 3.9Ah hammer next week and post a video here.
