Thanks mate! This is fun to do but very expensive. If I get 1000 subs I can get a cut off the ad revenue, which will help

Yeah it is kinda? I think the 171 maybe came out of the 12v range, so it's more of a scaled-up mini than a scaled-down medium hammer. I actually reach for the 171 more often when doing rock work because of the form and speed isn't the main requirement. It fits in a small backpack better and is easier to weild one handed

Indeed. The paradox of tiny hammers is that they actually need a fair bit of torque because those small bits go in really tight. DeWalt really nailed it with that little tool

I think you're looking at individual runs, not the averages. This test had 3 runs (first 3 columns) and then an average of those (4th column) which was ranked. Eg the Hilti was 12, 12.48,12.88 average=12.45

@@BoltahDownunder that makes total sense Sorry my bad

No worries! I should probably just show the whole data table anyway

@@engineer_alv I have Bosch tools and I consider them good but it just seems that Bosch has been lagging lately - they need to step up in a way with a greater selection of tools for their battery platform.

Yeah mate! I'm planning on doing just that but don't know exactly what tests to do. More DIYish stuff? Smaller holes in concrete, Besser brick, some light chipping...What do you reckon?

check out the new vid!

Yeah it's not much of a challenge, I've changed the material for future tests

Nice! Did you see my video about how to choose a drill for rock climbing? And I've used all of these for bolting climbs, is there anything specific you want to know about them? they're all good and except the Hilti I'd take them all

@@BoltahDownunder Hi mi friend! Yes, i'm very interested on the Makita DHR 182, the drill velocity and number of holes from a single battery (is that 45 for a 10x70 mm holes right?) is just beautiful! But i wanted to know how much it would wieight with a battery on! And if you really think that because of these numbers it is a deal breaker from, let's say, the HR166DZ that you suggest in your original video "drill for rock climbing"? For the record: i bolt pretty much 90% on crags, which imo is very different from bolting for alpine multy-pitch where indeed every gram counts and in general you need to bolt less protections! Thank you so much for this content, and keep up with the good video, adding the weight i think it's the nicest touch you can make (and maybe an average price for each drill to compare the quality/price also!

yes it's 45 holes, but 10x60mm. I haven't published this yet, but the DHR171 got 46 holes, compared to the 12V HR166 getting 21 holes. I put the weight in the normal review videos but these haven't been done for those drills yet. I weighed them for you just now. Here they are, with batteries: DHR182: 2.7kg, 45 holes (5ah battery) DHR171: 2.3kg, 46 holes (5ah battery) HR166: 2kg, 21 holes (4ah battery) For mostly alpine work I'd go the Hr166, the 12v drill is very good and super light. With 2x 4Ah batteries you can get 42 holes for the same weight as the 18V version (DHR171). For mostly crag work: Either of the 18V drills will be great. the 182 is 3 mode, a bit heavier, drills faster, the 171 is 2 mode, bit lighter, drills slower, nicer to use with 1 hand, fits in pack better. So, the main thing deciding between those 2 (other than weight) is going to be 2- or 3-mode. let me know how it goes!

Glad I looked in the comments. Just the info I was looking for. I like the fact that the HR166 is so light. The battery info is much appreciated. How does the drilling speed compare with 10mm holes with the DHR171? Thanks !

​@@BoltahDownunder Thanks for that. Weight is critical for cavers too. We've used 14V Makita BHR162s for 14 years now but they are shagged so it's time to go brushless for better efficiency. Our primary criteria are overall mass and holes per Wh, not speed. The hole drilling is 'quick and easy' for all these (compared to doing by hand which is 20-40minutes). We are driling 8mm holes. Also charging simplicity and over-discharge protection are important. Makita's stupid serial charging protocol, absence of over-discharge protection and self-bricking batteries caused us endless aggravation. I'm not sure if Bosch/Dewalt etc are any better. (I understand that Milwaukee are quite simple, and their tiddly 12V drill is probably most popular with expedition cavers for lightness and efficiency). But the Bosch kit looks good too.

Assuming you have batteries for all those brands already? Probably the GBH 18v 21. It's a bit more powerful than the 22, and only the Bosch have chipping mode out of the ones you mentioned. It's not necessary for the job you describe but useful to have if this is your first SDS hammer

@@BoltahDownunder the only batteries I have are the 10.8v and 12v makita ones... in fact I had also thought about the makita hd166d... but 1.1 joules makes me think a bit... if it makes me waste time when installing guides and hangers... .if it's slow... in any case for my job I have to consider the weight and manageability because on the ladder it has to make me tire as little as possible. obviously the gbh 21 has 2 joules. but is the gbh 21 something else to consider given that it doesn't have a cushioned body like the gbh 22? thanks

@@BoltahDownunder Do you advise against the Makita HD166D? Cerca su

I didn't think there are different versions, only different labels

SDS drill chucks have a bit of room for the bit to move. They're not a precision tool, and they're not tight like a normal drill chuck

I just borrowed the one from my m18ch. They're all the same neck, 43mm I think. They fit on the drill neck fine but don't sit fully straight along the front on the m12. Go for the smaller one I guess, as long as it's 43mm neck

It's a 1 inch drill so it wouldn't be in this video against these smaller drills. Also, I don't have one! If you want to see something specific, you can always loan me one to test, or donate some money so I can buy one

Didn't have one yet. I do now, stay tuned
