Tips for the new owners of this drill: 1. Always attach a rifle-like sling to the drill to prevent fall and also transfer the bulk of drill's weight to your body. This is for the safety to both user and drill plus less fatigue if used for prolonged period of time 2. Never allow any industrial chemicals esp. mineral oils to touch the surface of any parts of the drill. You'll damage the plastics as well as synthetic rubbers 3. Don't slam the drill on the ground if you want to put in on standing position. The electronic control board is located at the bottom, mind you 4. Don't fully pull the trigger if the drill bit is not in contact with the wall. You'll damage the hammer part of the piston inside the drill 5. Do grease the bit shank using SDS grease prior of drilling holes/chiselling/hacking.Extra grease for hacking.Feel the gearbox area (at the instruction label) using the sole of your hand; if the area feels hot then stop & give your drill a rest until it feels cold 6. Do not rotate the selector switch if the drill is still running. Unlike the previous EC version this action will damage the gearbox 7. Always use EPC mode if you're not sure about the strength/materials used for building the wall.This drill will damage both cement/brick walls in full power mode due to high impact energy (2.7 joules). Use 100% mode only for chiseling, hacking and drilling large holes like 25mm 8. Procore 4ah (total weight 3.5kg) is more than enough if you're doing a light-duty job (like drilling small holes for electrical installation). Both 8Ah (total weight 4kg) and 12Ah are for serious heavy-duty jobs like hacking wall or chiseling.Always bring the charger together with the battery 9.Regularly do maintainance regime.Wipe out dirt using provided machine cloth. Clean inside the sds-bit holder using cotton buds. Use cotton buds laced with metal polish to clean the battery terminals and then spray them with electrical contact cleaner. Lightly grease the sliding slot of the battery using a very thin layer of sds grease. Check the sling (if attached) for any damages/rusts/tears. Test the kick back function by rotating the drill using both hands at the same rotating axis. If the working light is dim then polish the light window using plastic polish 10. Disconnect the battery from the drill before putting in within storage box. The electronic board will still consume the stored energy within the battery even if the trigger is not pulled/in lock mode. Avoid storage place with low temp & high humidity as this will disrupt the board & causes the drill to have a "start delay" problem (which is reversible) This cordless drill is a high-tech, high-quality, upper-range machine designed for heavy duty work with many functions as well as safety features. Take care of this drill and it will help you to make your daily job more easier than before
I bought the GBH 18V-26 in a one-off sale for about 150 EUR. Best tool I ever bought for the money. Sufficient power for most applications, reasonable weight, and with the GDE 18V-16 additional dust extractor, it's absolutely perfect. Also, I personally think that the non-F version is better. You can buy all sorts of non-percussion drills and use them normally, and also, longevity-wise, the quick-change mechanism will suffer mechanically long term. I used to have the GBH 240 F and never used the "normal" chuck - not a single time. For common drilling, pretty much everyone has some kind of other solution, typically a smaller and lighter 18V or 12V drill/driver. This was never meant to be a universal drill to cover a wide range of applications, not to mention driving screws etc.
All my tools are Bosch and not one has let me down. Bosch are especially good when it comes to hammer drills. I've just ordered the bi turbo 18v 34 cf, the bigger sds plus, got 5.8 Joules.. I had the 36v li before, brilliant bit of kit.
They are both great. I would base my choice on the rest of the range. Bosch seems to have more safety features and Makita usually has a little bit more power (not a big difference though). If you already have batteries for one of them, I'd just buy that brand.
@@macvos as far a sds plus drills are confirmed, I looked at other makes, because stock of the 34 cf were so low, but I couldn't find anything as powerful, so I waited for the 34cf to come back in stock, even my old bosch sds was 3.2 joules, my friend was going to buy a makita at 1.6 joules, so I sold him my old bosch, he's more than happy with it. I've ordered the dab bosch powerbox radio now, I'm waiting for stock to come back in, due to covid affecting parts.
You won't be disappointed. I've been working semintensively for the past two months with any trouble. Still strong as the first day, besides bit dirtier 😂
Ended up getting one and love it, only issue is anything under a 8ah will only last about 10,15 minutes but the 8ah will last hours. Just spent a day chiseling a floor covered in an inch of cement and tiles and a brick wall with half an inch of cement with tiles and it worked great
Where is it made? Hungary, Malaysia, China, Germany? I've noticed Bosch Pro rotary hammers or drills seem to be made in any of these places, with no discernable pattern. I've seen two sds plus bosch rotary hammer next to each other at a store. Almost same size, power and impact force. The bigger one from China, smaller from Germany. But all their large sds max hammers seem to be made in Germany. Go figure...
Do not store this drill together with the battery unless you have a spare battery because from my observation the electronics within the drill seems to drain the battery's juice if the battery is attached to the drill for a long period of time btw, this drill is a beast. and also a brick and cement wall destroyer the impact energy is too strong and destructive
A nice feature of Bosch pro 18v power tools is that they have two notches in the battery slot, one in front of the second notch, so you can slide the battery in part way, and it will latch on the first notch, so the battery won't come off by itself, but the contacts aren't connected, and even like that it still fits in the L-boxx with standard insert.
I dont understand why people want the F version with the changeable chuck. It makes the tool unnecessary even longer , making the drill bit even more wobbly. Come on man. The shorter the better.

I don't do construction anymore but this video still made me want to get one lol It's amazing how you can do all of that cordless.

This is what I am looking for! The changeable Chuck.
What kya 4" chhodae may 1 feet niche ja skta hay plants nikalne ke leye batae thanks
Excelente demostración!!
Thanks for making this video
BEAST MODE i wil buy one
I'm glad, this is the best on its weight range 👌
Looking at the Bosch website and i don't see this "F" model listed in the inventory of tools they currently offer
Will it drill a 30mm hole through brick okay?
Bosch do a bigger one, bi turbo 18v 34 cf, it's an sds plus with 5.8 joules, I've ordered one
Do you have any video or manual about how to remove the drill bit. Thank you
just pull the collar and remove the drill
Running hours??
Malaysia did not offer the changeable Chuck, 26F therefore Milwaukee 18V rotary hammer trump over the Bosch in this category.
Thx for the info. I'm still figuring out witch one to buy. The bosch gbh 18v-26d or the 18v-26f
...and which one did you buy?
I have to decide between GBH 18V-21 and GBH 18V-26F :D
considering bosch and makita ,which one do you guys suggest ?

How long does a battery last?
It depends on the function. For example, with ProCORE 8.0 Ah battery I can work intensively like for 2-2,5 hours with chiseling function.
@@woodworkingbarcelonaii9413 that's actually better then I expected, think I'll have to get myself one

GBH 18V-26 F is/was made in Germany
@@d.vantreeve1560 thanks, I've just bought one with an L-boxx and two 8Ah procore batteries. Looking forward to do some jobs with it.
@@marsdeimos4301 the device is one of the best cordless rotary hammer drills on the market.
Do not store this drill together with the battery unless you have a spare battery because from my observation the electronics within the drill seems to drain the battery's juice if the battery is attached to the drill for a long period of time
btw, this drill is a beast. and also a brick and cement wall destroyer the impact energy is too strong and destructive
That's very good recommendation. I'll store separately from now. Thanks Zul!

Anyone ...used a 18v 36C ...it's supposed to be 7 Joules
That's good for a cordless
