method

That's correct, but keeping in mind the flexvolt 6 is 108wh, so 216wh for the two batteries and the metabo 2 x 18 is 252wh. Also it's approximately 800mm of cutting an average of 12mm steel. The section is approx 11mm and the flanges are approx 13mm. I only had 2.2mm cutting wheels also, I had run out of the 1.9mm discs. That makes quite a difference in run time.

In regards to the heat in the batteris - I played around and cut a 450mm H beam today. To complete the cut I went through two 6ah flexvolt batteries in the DCS690 and half of one full charge of 7ah LiHD batteries on the metabo WPB 36-18 LTX BL 230. When comparing the two one directly after the other, the Metabo has a lot more power when the dewalt is running the 6.0's, in saying that though, the dewalt has great power too and definitely has more power when I put a 9.0 in. The metabo can be pushed harder, but is more awkward to vertically cut with, and the dewalt is much more comfortable to use vertically and cuts slightly deeper. Horizontally it's the other way around, except for depth of cut obviously. The metabo batteries got warm, but not as warm as the flexvolt batteries, both packs were too hot to charge as in the photo below. The dewalt batteries also get hotter due to them being fully enclosed in the tool with its water and dust tight seal. The 9.0 got just as hot when I did another cut. After a few minutes on the charger both started to charge. It was also 32 degrees here today. I'd find it hard to believe that the batteries would get as hot as they did using these tools when using an impact driver. I've used my AEG and milwaukee impact drivers to screw 12mm coach screws into redgum non stop with 5ah batteties until flat when i put up my retainer walls and the tool nor battery got hot enough to worry about, pre drilled of course. I'm wondering what it is that is causing you so much grief when you say you always have several out for repair? Here is a quicker method of cutting the beams today (there is actually 2 x 450mm H beams in that cut) if only it was cordless and didn't weigh so much 😄 https://1drv.ms/v/s!Ap5wHcMpyIC-hZsf9RbB50Ne6zQJAQ Forgot to mention my batteries go straight onto the chargers once drained, regardless of heat and are always stored fully charged.

I can definitely now confirm that after much use, the LiHD batteries keep a more consistent load on the tool. The 7.0ah also lasted almost three times longer than two sets of 4.0ah batteries when cutting 100x100 SHS 8mm thick. Loving this tool! Just wish metabo would hurry up and release the 8.0ah batteries!

Sure is! Now that will charge a high capacity batt in no time!

I guessed that then I thought it was some abbreviation for a boss of some sort over there 😁😁 Putting weight aside, have you considered using bigger tools which obviously work a lot less than using small light weight tools and running them flat out? I don't find weight an issue if the job is getting done easier and quicker. A lot of people disagree with that but the only time weight gets to me is using a demo saw cutting above the waist or using a jackhammer on a wall in which options are limited for both of those applications.

I'm in Australia, it gets hot here, some days over 40+. What is an OCD?

😁 I also had a brand new one replaced. Not sure if it was defective or not but it would only ever show two LEDs on the charge status when fully charged. Walked into the store I bought it without a receipt and walked out with a new one two minutes later.

The most powerful Hilti charger available here is 350w. I doubt that would charge any high capacity battery in 15 min unless there is a much larger version available where you are? Hilti make quality tools but you do pay a lot more for them because of their service options. There is no single tool company who own the rest. I have cordless dewalt, husqvarna, paslode, metabo, hilti, milwaukee and AEG as well as corded milwaukee, Bosch, protool, hitachi and makita and im sure ibe forgotten a few. Each tool I buy is best suited at the application I'm using it for regardless of brand. Being on multiple platforms doesn't bother me. We use tools harder than most other contractors. I've burned out 3 hitachi jackhammers in one night on a job once. When I say non stop I mean finger on the trigger under fulll load cutting without stopping until the battery is flat etc. If you have so many issues with batteries and tools then go for Hilti, they will deliver replacement tools and batteries to your site and service for free for two years here. All of that is built into the price of the tools and if it saves you on down time it's paid for itself within the first two call outs. I've had problems with all of my tools including Hilti (except for my corded makita, protool and cordless husqvarna tools so far).

What model Hilti charger charges a battery in 15 min? Also what size batt are we talking? The fastest chargers I have are the metabo ASC Ultra which does 7.0ah LiHDs in about 45 min and the QC330 which does my 338wh battery in 55 minutes. The QC500 does it in 35 min but charges all smaller batteries in the same amount of time as the QC330. I put hot batteries on the charger all the time (chargers with built in fans) and if they are too hot the chargers cool them before charging and some of the metabo batteries are 8 years old now and still going well. I notice when I put a milwaukee 9.0 on my old milwaukee charger it got hot and cut the charging process (no fan). Dewalt flexvolt rarely get warm when I use them and I'll use them non stop at times until the battery is fully discharged.

The saw is 2100w for anyone looking for that info, took me a while to find it!

I cut brickwork today and it cut better than I expected. I had to cut both sides as it's approx 20mm short of cutting through a full face brick. Not a problem though as it breezed through the back cut. I'd say it will cut those no worries at all. As with all cordless/light electric tools you really need to let the tool do the work unlike high wattage corded or gas powered tools where you can really push them. If a housekeeping pad is what I think it is, it should cut it like butter. I'd recommend several 9ah batteries for it though.

I think a lot of people here in Australia bag AEG because it is only sold at Bunnings. I've heard that a Milwaukee rep said to someone that the AEG factory is directly opposite the Milwaukee factory in China and that some tools are very similar, being both owned by Techtronic Industries it may be true? I own tools from both brands and some of the newer AEG tools are worth the money you pay. They are quite powerful and I've dropped impact drivers from the roof directly onto concrete and they survived. I've ran the tools continuously for hours (literally) and never had any issues. I once cut out 1km of insulated steel duct work from a school roof space with a corded AEG recipro saw (in 1.5m lengths), it got hot to the point where I could feel it burning through my leather gloves and it kept running and running. The best thing with AEG is the warranty, simply walk into Bunnings and walk out with a new replacement tool. I'm not sure if Rigid is the same overseas? I've had many issues with new tools (Bosch blue, Milwaukee, Stihl, Dewalt flexvolt and even my Metabo tools) and I was questioned about how I used the tool and also about the job I was doing every single time from other stores and on top of that, had to wait for repairs. Hope this helped!

Finally found a store who stocks this and picked it up yesterday. Awesome, handy little tool for anyone looking at purchasing. Needs 12.0ah batteries though but it runs well and has decent run time with the 9's. I haven't used it much but it feels less torquey than the cordless 9" Metabo grinder, I find that when the grinder is at full speed it feels more powerful when cutting. The Dewalt is much more comfortable to hold when chopping and wall sawing even though the Metabo has the 3 position handle and rotating arm. The brake is super fast and it actually feels quite well built. I just wish the guard was able to be positioned like a normal demo saw (just pull or push into desired position as opposed to 5 fixed positions). It seems to have a safety mechanism (not sure if mechanical or electronic?) but I had a tungsten circular saw blade on it for part of the day whilst cutting timber and when it jammed it cut the power instantly which was nice.

Juat an update for anyone considering purchasing. I cut concrete and bricks with a diamond blade and it powers through like butter. I cut 4 meters of brickwork and the 7.0ah only used 1 bar of battery. For a rating of only 1ah more than some of my flexvolt 6.0ah batteries, the lihd 7's seem to last like a 9ah flexvolt battery. The more I've used it the more impressive the tool is.

The worst thing about the metabo cordless 9" grinder is the case handle. I once had another tool case like this although I can't remember the brand. As in the picture, when you use the handle and put the grinder down onto it's side it squashes your fingers and nails between the handle and the big moulded piece of plastic! With almost 10 discs, the grinder, 6 batteries and tools in the case it sure isn't light! If anyone from Metabo ever stumbles across this, please make a note of it!

The first day I used my first new Milwaukee half inch impact wrench on a job, the detent pin fell apart. I was 5 storeys up dismantling a steel roof structure. The socket obviously wouldn't hold so i wasted half a day taking it back to get a replacement. Use warranties as much as you can, that's part of what you pay for when making your purchase.

I must be going mad, I had thrown the dust hood for the 575 into my tool drawer and only found it today! A year later 😖

I've used the framing gun, although heavy it drives nails like a genuine pneumatic gun. It drove nails flush into redgum and cypress pine where the paslode didn't, every time. I would still use a paslode gun if I were a chippy on a roof as I think the paslode is faster and it is definitely much lighter. Generally no hardwood is used on the roofs here in au either. My friend who bought one said it did pay for itself within a large job or two by not having to buy gas so there is a big cost benefit for framers. It is much better than the Dewalt.

I used the grinder for several brief periods over the last few days. The grinder definitely feels powerful and as I trusted, the rotating handle works wonders. The grinder has a soft start, it takes a few seconds to power right up and is noticeably slower to rev to full speed with a brand new grinding disc installed as opposed to the slitting discs. Spark guard works as designed. Removal of material is fast when grinding. Those who use different size grinders will know the difference between a 9" and anything smaller and the difference is impressive being cordless. With enough pressure, the grinder does cut out with the overload light coming on (when grinding) but by letting the tool do all of the work it never stopped. You will not get more than 5-10 minutes of hard grinding and that was with the 7.0ah batteries. If ever Metabo make some 12ah batteries, the grinder would be much better. I cut approximately 1 meter of 4mm steel very quickly with a cutting disc and the batteries did not lose any charge. When the 7.0 LiHD batteries went flat, I threw on my old original 4.0AH batteries. Power wise I couldn't actually notice a difference over the brand new LiHD batteries and the 4's are 6 years old. One other strange thing I noticed was that I seemed to be able to push the 4.0's a lot harder than the LiHD 7's without the grinder going into protection mode. I am wondering if there is some additional circuitry in the LiHD's that prevent them from being pushed? Overall, I was very impressed and having the option to use two 18v batteries I actually prefer as opposed to having to buy new 36V batteries and charges. The only issue is we need more watt hours, at least >300 or even 400+. I modified my T536 LiXP husky to have a 14" bar with a standard size chain as opposed to a mini chain and with the 9.4ah 36v battery the power and run time is perfect which is why I think we need much more wh.

Bit the bullet and picked one up today with 2 x 7.0ah batteries and an ultra charger. Need to repair an excavator bucket tomorrow so will see how it goes grinding and cutting with both the new 7ah batteries and some 6 year old 4ah batteries!

Hands up for wireless tool battery charging on the fly 🙂

It sure does! I must agree.

Cordless grinder when grinding, not slitting, table saw when ripping anything > 50mm in depth and the cordless orbital sander from milwaukee drains a 9.0ah in no time!

I just received an email from metabo, the 8.0ah will be coming out early 2019! Such a shame, I held the cordless 9" and it felt so much nicer than the Milwaukee. I didn't want to purchase without 8.0ah batteries. The extra juice over the 7.0 @ 36v makes enough of a difference for me to decide not to purchase. Any ideas why metabo is playing catch up to milwaukee and dewalt in terms of battery capacity here down under? Even AEG has a 9ah battery available at Bunnings!

Melbourne, Australia. I was even told the dewalt demo saw is 4 months away even though it has a release date of the 31st of september!!
