I paid $79 for the brushless drill kit with 4 attachments and 2 batteries...I'm interested in this SDS attachment, but I can't bring myself to pay anywhere near this much for it... Maybe like $30-$35 😂

I can understand that perspective. On the other hand, if you need to put some holes in brick or concrete and already have the Flexiclick, this is a heckuva lot cheaper than buying any other battery powered SDS rotary hammer.

This system would be great for something like alarm or camera installation. You could carry all the tools you need in one tiny little bag.

Absolutely. Had I not purchased an M12 FUEL SDS+ rotary hammer for anchors LONG before this Bosch attachment had released, it is quite probable that I would have already purchased this at $66.75. I'm not saying this is an unreasonable price at all, just that they would have to do WAY better to get me to buy it now. There is times on the job it would be nice to toss one small kit into a backpack and have all the bases covered.

How in the world did you get that for $79? Is that the Chameleon GSR12V-300FCB22 ? I see it is on Amazon right now for $129.00. I paid just a little bit more last month, but I thought it was a good deal at the time.

Yes, the Chameleon GSR12V-300FCB22

Read through the comments for the story. Long story short, Lowe's doing a local price match with Tractor Supply (who had the brushless info on their site showing in store only sale, but the brushed version actually in store...so Lowe's price matched the brushless)

I have a plug in regular SDS rotary drill that is WAY more powerful than this would be.. but I still want this one. You re right though, $30 seems like a good price for something that is most likely a gimmick. I cant see using this on big jobs. But for a few small holes in concrete, sure. But I have a cordless hammer drill for that anyways.. in reality, id probably never use this

there are quite literally zero reviews of this attachment online. All the reviews on the amazon link are for the starter kit itself, and googling it on other sites that sell it also turns up zero user reviews of it. Literally the only mention I could find with a video is a paid sponsorship one on tik tok.

I see the appeal for a quick hole in masonry, but I really want to know how underpowered it would be compared to my corded rotary hammer. The portability and much lower weight would be really appealing if it could handle light tasks, but I don't want to spend this much on an attachment if I regret using it everytime to drill a hole.

Here's a quick review. Within it's recommended range, up to 3/8", I don't find it underpowered at all. Not a gimmick at all.

I own the SDS attachment in both 12v and 18v. The 12v attachment locks in very, very confidently, more like the 18v flexiclick attachments in how it clamps into place. In the hand, it feels hefty and precise -- it weighs about what the rest of the drill and battery weigh together. It smacks and actually does hardened cement as a rotary hammer should, because when connected, the tool fully becomes an actual rotary hammer and will smoke any standard drill with hammer function. Even the depth gauge, surprisingly, is steel, not plastic, and it's well-machined, like the rest of the assembly.

I've used the 12v mostly for 5/32 and 3/16 holes for tapcons and other screws. If you have good control with a 12v drill, this setup will give you nice clean holes. It can manage the occasional 1/2" hole, but eats up batteries doing that.

For overhead work and light-duty fixtures, this thing is really fun to use. If this is something you plan on 'just tossing in your bag', be sure to stash it with SDS plus drills (and a dust mask, silicosis is no joke) so you don't forget.

When I'm looking to anchor something with serious weight where I find I'm checking the load ratings of my anchors, that's when I step up to the 18v or pull out a corded Bosch Bulldog, but that's not the kind of work I do very often. (I generally prefer the 18v to the corded, because I've found the corded to be underpowered over 100' cable runs, and affixing things outdoors is where I often need the extra power.)

Cheers

This YouTube review, although in German, is informative. Subtitles and translation worked fairly well for me. https://youtu.be/Tc2qIzRn2WM?feature=shared

It's $99 now. Was as low as $74 on Amazon business for a brief time.
