Bosch GBH 18V-21 rotary hammer drill, seems like a pretty good price considering the redemption offer at the moment, redeem a 5Ah starter set from Bosch. Redemption is available 1st May to 30th June 2024
Spotty stock nation wide, a lot of 1-3 in stock.
https://nrby.in/bunnings/0215168
Price is between $340-$365 elsewhere.
I ended up paying $189 with PowerPass, but then no OnePass, so it was $10 delivery.
Yep, I did the redemption yesterday and it got approved, but it's up to 8 weeks for delivery.
"Please allow up to 8 weeks for delivery from your claim approval date."
Is the only reason for this the starter pack redemption?
Edit: Given corded gives more power. It's hard to see why a lot would want a cordless version given the tasks you use these for,
For tradies or owner builders working on a site with no power .
Seeing as they can be used like a mini-jackhammer there are plenty of use cases away from 240V connection besides just dragging out extension leads and packing up every time .
Absolutely, personally I've used hammer drills like this countless times to drill 6 - 12mm holes in concrete for various fixings such as star plugs, knock ins, dynabolts etc. I can not imagine having to bust out an extension lead every time these days.
You're definitely paying for convenience over power. Also weight is a lot better, with battery, this Bosch is about 3kg. A cheaper, but more powerful corded will be 4.5-5kg.
I'd say for most people using this around the house, this Bosch would be fine.
From my very limited research, the 18V-21 is the old model (mid-2020), the 18V-22 is the new model (early 2023). They're aimed at a very similar market, they're effectively the same tool, but the new model has better hand positioning (higher on the tool, so you push in line with the drilling)and it has some built in vibration dampening too.
On paper, the old model actually has better specs, higher impact energy, higher impact rate and faster speed, for whatever that's worth.
Thanks. Sounds like I should buy -21. My usage is to remove tiles (combining with a chisel bit)
They are an absolute godsend for removing tiles.
got one. It is much smaller than I thought.
Put a bigger amp/hr battery in it ,
it should pick up the pace a bit .
I don't need it, but I really want it.
I want it but OOS here in Perth
halls head had/has stock one pass it
Tongue twister
I think I got the last one from Cockburn Central, there was also one at Bibra Lake when I was buying, but long gone I think
I used to know a girl with that nicknamed …
You need it to complete your dentistry kit
so tempted to buy this but I bought the ozito corded last month for an urgent job. the thing is powerful but damn it's massive
cordless, compact is so much better to use when up on a ladder or in a spot with no power access
Exactly! I have the corded Ozito too. While it is cheap and powerful, I often still use a drill with the hammer function. I would rather waste like 5 mins with a drill to drill one hole in a brick than use this heavy Ozito (which takes only seconds to drill hole)
same! i had to do a 20mm wide hole through double brick so had to whip out the ozito for that
for general wall plugs i still prefer my makita cordless hammer (so much lighter and can get into tight space)
operating the ozito feels like i'm war machine!
Tempting as it’s such a good deal. But I have the Ozito corded rotary drill and i don’t use it often enough to justify spending extra on a cordless tool. I use to use my Milwaukee M18 Fuel hammer drill and hated drilling into brick. I purchased the Ozito corded rotary drill and it’s amazing how much quicker is it. Holes that used to take minutes to drill now only take a few seconds.
the power is amazing but the inconvenience of it especially up on a ladder or in tight spaces makes it less desirable
Tempting with the starter kit but probably won’t actually use the damn thing eh
Maybe the ozbargainer in me is going soft, wouldn’t have stopped me in the past
I have the Ozito corded one. Its massive and I often just go to my normal drill with a hammer function.
Is this worth it for around the house DIY? Do I need the 'SDS' one instead?
This is SDS plus.
It is really difficult to explain the differences without almost writing an article. But I will try.
There are basically 3 types of hammer drill. Your std hammer drill which is pretty much only useful for the odd small hole in masonry, eg 6mm or smaller.
Then there is the rotary hammer. They come in 2 types. SDS plus and SDS max. the SDS plus type is what most people know as a rotary hammer. he SDS max is for really heavy duty work.
The hammer drill and a rotary hammer operate in a completely different way. In the simplest terms, a rotary hammer hits way harder and drills through masonry far faster than any hammer drill. .And for most uses is well and truly up to drilling larger diameter holes in a fraction of the time.
We used to do air con installs and used a mix of 18v and 12v SDS plus rotary hammers. The 18v was for chiseling the brick out for the pipe work, and the 12v for drilling the holes to mount the brackets and pipe duct work for the external unit (condenser)..
So,TLDR, if its just a few small holes, the std hammer drill will do the job. But compared to any rotary hammer of any voltage, cordless or not, they are about as useful as a chocolate teapot.
Thanks so much for the explanation! I tried to google and see the difference between hammer drills and found that rotary one is the 'better' one, but got confused when some products under rotary hammer drills category in bunnings dont have 'SDS' on the product name..
Coupled with the fact that the description for this one says SDS plus confuses me even further haha. Managed to grab one tho. Fingers crossed they dont cancel as it's delivered from some farther store as there's no more local stocks.
Happy to help. Hope it wasn't too confusing. Bunnings website is definitely not the best with descriptions and specs.
For the record, you will have to buy some SDS plus bits. Fortunately they are not expensive. My preference is for Milwaukee bits. Reasonably priced and last a long time.
If you are interested, check out this video in the link below. It explains how a rotary hammer works way better than I can. Start from about 33 seconds in. It is only about a 30 second watch, but def worth a quick look in my opinion.
So would you say that an impact driver and a rotary hammer should cover most materials/use cases, or do I still want a drill?
I would say having a drill and an impact driver first, then a rotary hammer if you doing any reasonable amount of masonry drilling.
A rotary hammer can be used to drill into other materials using an SDS chuck adaptor and using in rotation mode only but they really aren't ideal. Or particularly nice to use for that as there is a bit of play in the SDS mechanism and they are not as well balanced as a std drill.
In saying that, my impact driver is probably my least used tool. I generally just use one of my drills for screwing anyway.
@revheadgl: Thanks. I have an old corded drill that has been serving me quite well for all sorts of drilling and screwing, even into the floor. Just wanted something smaller, tried someone else’s Makita impact driver and it feels a lot neater. Been thinking about getting one ever since. Maybe I should keep my old drill and just get a driver.
Personally I've gotten away with a regular hammer drill/driver (non-rotary) and an impact driver, and I've done quite a bit of stuff around the house, and drilled quite a lot of holes in the walls. Even using SDS bits in the basic hammer drill, still manages to drill 20mm holes through double brick.
@jdawgydawggy: lol you have to if you are on the gold tier ozb membership, otherwise you are downgraded back to bronze 🤭
I’d be all over this if I hadn’t gotten a Metabo kit for $130 in a previous deal ,
In fact I bought two so I’d have two batteries and chargers and the sold the unused extra rotary hammer for $120 .
I think it’s just gone oos for delivery, ok when I added to my cart but then unavailable at checkout. No stock near me on south east melb either
I got free delivery even though I do not have OnePass.
Bought one and it is time to sell my Ryobi corded drill
Great drill if you can get one. Makes drilling into full brick wall so easy.
This is a great deal. I have the slightly larger D handle model GBH 18V-26 with no regrets. If you are a DIY with junk tools get this and and impact driver skin and you’ll be set for most things.
I'm confused by what that thing is meant to do. Is it so you can use your sds drill with normal bits or use sds bits in a normal drill?
The fact its got a normal chuck makes me think the former but the description says for use with light hammer drills which would make it a useless addition to this deal.
Yes the former. Heavier rotary drills lack accuracy and you will simply break smaller bits due to out of round. Personally I’d use an impact skin for everything else, using 1/4 hex shafted drill bits.
I got this last time they had this same redemption deal 5 months ago with powerpass. Bunnings have had this drill at $199 for so long for some reason. It's a great buy.
I think its because this is the old model, and they're trying to clear out old stock
I got a cancelled order email this morning (Victoria) due to lack of stock available for delivery.
i guess the same retard negged your and my comments.
Got refunded lol
These are great for small jobs like drilling holes in masonry, removing tiles etc they are fairly gutless for any sort of demo work though, I have one form the last deal here.
Dammmm. Last Oct's deal only got a battery without charger. I ended purchase one from fb
I can't find the redemption offer on the Bosch site for this item. What am I doing wrong?

I got one delivered for free from Rosebud, Redemption accepted. This is a great deal. I have virtually all of the Bosch blue battery tools now. Just need an orbital sander deal
Snagged the last one from Belmont WA, thanks OP great deal 🤝
This looks great - got one for $189 with PowerPass also.
Do I really get a battery and charger also????
