Dewalt 18v Xr Li-Ion Brushless Hammer Drill Driver - E209 @ Woodies

garion

I don't know much about tools but this seems to be a decent Black Friday deal at Woodies:

https://www.woodies.ie/black-friday-deals/dewalt-18v-xr-li-ion-brushless-hammer-drill-driver-home-delivery-only-1127793

Screwfix have it for GBP299 or E447 (:eek:)

Amazon resellers have it for GBP267

Handy Hardware (never heard of them either!) have it for E559

I use my drill so little that I can't justify it but hopefully others will find it useful.

Actually, looks like deals are not stackable so can't use the 10% too. Also it's E5 for delivery. Think that's done it for me!

The battery looks small in the woodies photo. It's only a good deal if they come with two decent sized battery's.

I'm not saying that it's a bad deal. Just make sure you are compairing like with like

I just checked it out. Woodies batteries are 2ah and screwfix is 5ah. Screwfix is the better buy

It looks to be "2 x 2.0 Ah" which is fine. They charge fairly quickly.

A year ago I Bought "Dewalt DCD796D2 Combi Drill 18V XR Brushless Compact Lithium-Ion (2 x 2.0Ah Batteries) DEW-DCD796D2-GB £146.00"
That looks like the same kit. The site I bought it from has it at £289 now though.
It is a great drill. I don't feel I need the 4Ah batteries. The only time when I went through batteries quickly was using a wire disc to take paint of a house.

It's not how quick they charge or how long the charge lasts. 2mh isn't strong enough to drill some holes or drive some long screws. The big battery improves the quality and strength of the drill/screw gun.

I've seen the 2mh going for less in B&Q on and regular weekend

I bought the same screw gun with two 4ah batteries in Grange builders supplies for 250

Eh you are talking crap,
A 1Ah (not mh)battery will drive the same screw as a 5Ah battery .
It wont drive as many

Absolute nonsense,

The drill has a fixed wattage motor at a fixed voltage. Every battery gives the same output in terms of voltage and current, the difference if the storage capacity which range from 1.5Ah to 5 Ah.

The Ah stands for amper hour, not current output..

This is 100 percent true. Every tradesman knows this & there are Youtube videos proving what we already knew. Why do you think we always pay extra for the bigger battrys

Batteries packs are usually made from the same size cells internally. larger capacity = more parallell cells = lower internal resistance = higher current available = higher torque capability especially under stall conditions

The main difference is the battery. The bigger the battery the more power & strength you will get out of the same drill.

1.5 is a tiny battery and won't deliver much.

imo it's perfectly fine for work around the house.
Once you have two batteries you'll be fine, swap out and charge as needed.
I noticed from the Screwfix link above they have a nice Hitachi/Hikoki drill with some nice capacity batteries for under €200, that would be a better buy than what's been linked to above.

4ah hour batter is not more powerful than a 2ah hour battery.

Its just not.

The actual draw from the drill, particularly the brushless drills is limited by a PCB in the drill and or control pcb in the battery. The max current draw and voltage of the 5ah and 2ah dewalt batteries is identical. The video with the Ryobi drill is demonstrating older tired batteries. I have a 4ah battery here that does the same thing..

The reason tradespeople pay extra for the larger battery is they don't want to be swapping batteries ever 20 minutes and as you know every single charge and discharge of a battery impact on life.)

By your logic using same drill with a 9ah flexvolt battery should rip my shoulder off.. It doesn't.. Using the flexvolt battery just results in a slightly heavier drill and even longer between battery changes,

Also for those comparing to the €150 B&Q drills.

They are not the same drill. Dewalt have a huge range of battery drills, all looking the same but different ranging from cheapo DIY rubbish to the gem that is the DCD996 brushless.

You can buy the DCD996 on toolden for £125 but the DCD785 is only £40

The Dewalt range of tool is constantly being updated and can be a confusing mess at times..

Have you watched the YouTube video? Any tradesman who uses these all day every day will tell you the exact same thing. The lower rated battery will be less powerful. I know that the rating is stored capacity and not related to output strength but higher rated batteries do in fact give better results with actual power.

Look originally I just wanted to point out that the offer in Woodies has a tiny battery and not compatible to the screwfix offer and the same drill is often as low as 150 in B&Q. Weather you believe what the difference in batteries can do or not do doesn't bother me one way or the other.

OldMrBrennan83

Use one of those all the time. 2Ah is fine so long as you're not drilling massive holes in stainless or anything. Very good price as it's the one with the metal chuck too.

That's not true. I've been using cordless tools as a plumber for over 30 years and I have seen with my own eyes a fully charged 2ah stalling on a long screw into hard wood yet changing the battery to a 4ah or 5ah allows you to drive it fir in or fully home.

There is a YouTube video on page one showing this exact thing. It is not trick photography or photo shop. It's a genuine video.

I would much prefer to carry a 2ah batteries rather than a 5ah as they are much lighter and I lug my toolkit into 7 or 8 bathrooms per day. I have a cordless dewalt drill and impact driver in the tool bag plus tools. It's a heavy bugger. I can't do this because the performance from the smaller battery is not as good as the 5ah. Not the length I get out of a charge as I can charge in the van & constantly have fully charged batteries.

Before more posters say that its not possible I suggest trying it themselves.

Once the lower capacity battery has the same voltage and internal resistance as the higher capacity battery, the power available to the tool will be identical. This is not a matter of debate, it is a matter of physics.

How do you even know that the internal resistance is the same with smaller & larger battery?

It's not even a big secret. Anyone who has used cordless power tools daily will have come across this.

No I have not watched the video.

Power in Watts, which is proportional to torque, is given by voltage x current. Modern Lithium-ion batteries have a pretty constant voltage until they are ~20% of capacity. The only variable, is the max current that can be drawn, under heavy load. Under heavy load it is possible that the electronics in (some) smaller batteries would limit the current more than in a larger unit. However, any such variation would be small.

In general, a bigger battery will take longer to reach a discharge level where the battery voltage drops, therefore the performance of the drill will be optimum for longer.

Maybe if you actually watched the videos you wouldn't post stuff that just isn't true. In the youtube below they actually test dewalt 2 ah, 4ah & 6ah & demonstrate how the torque power is better with the 4ah & 6ah.

you are simply wrong. I started using battery drills as an apprenctice sparks, then kitted out by workshop at home with grinders, torque wrenches, die grinders shop vacs etc all working on classic cars.

In my day job I have over 20 vans all kitted out with battery tools, drills, drivers, 6" grinders, metal circular saws, saber saws SDS drills 18v and flex volt. we rarely uses corded tools any more, some of our vans don't even have extension leads.

I have reps beating down my door trying to sell me tools and engineers techs, trades trades all looking for new tools. We just bought a flex volt chainsaw to try and are moving all our SDS drills and grinders over to flex volt as they are being replaced..

I have litterally hundreds of batteries of all capacities in 10v 18v and 56v and can categorically say that the a torque gun running on a new 2Ah battery operates identically to one on a new 5Ah battery. same for the drills. All the engineers love the higher capacity batteries because they last longer need to be charged less frequently and as a result they don't need to carry as many..

I have 2Ah batteries here that will out perform 4Ah batteries. because the 4Ah batteries are old..

I never suggested that the torque power wasn’t better, I stated that any variation would be small. I looked at the video and I’m wondering whether you actually understood it. It shows a variation of around 5% between the 2ah and 4ah batteries. That’s about the difference between a Lithium Ion battery fully charged and 70% charged - a small variation.

I totally under stand the results & they backup what I have been saying all along, The bigger the battery the bigger the torque & the faster the rotation. Other posters incorrectly insist that there can't be any difference between 2ah & 6ah batteries. They actually believe that it's impossible & it breaks the laws of physics.


You say 5% is small But a 5ah battery gives a 9% improvement & the 6ah gives 12% improvement. A 12 percent improvement in torque just by changing battery size is huge! Especially when it's "it's impossible & it breaks the laws of physics."


A 9 to 12 percent improvement on torque just by having a bigger battery is definitely something to consider when shopping for a cordless power tool. I effects my decision every time I buy a power tool. When you have a power tool in your hand everyday as part of your job 9 to 12 percent makes a huge difference

knipex wrote:

You are talking nonsense now. There are videos with genuine benchmarking tests with genuine results showing that the bigger the battery the better the torque. Because it doesn't fit in your little bubble then you dismiss them totally.

Don't show me YouTube videos proving that the earth is flat because that's off topic. How about you show YouTube videos proving what you are saying is right. That makes more sense to me. Coming on saying something isn't true without any proof is not helping anyone.

I'm trying to show others thinking of buying this or other offers that there is more to battery size than charging & run times.

There are much better offers than this one. The amazon one with two 5ah batteries for £202 beats this one hands down. The woodies screw gun is the exact same one B&Q often have for €150 with 2ah batteries

I don’t know where you’re getting the 9 to 12 percent figure from. You said:

This gives ~5% difference. Suggesting that this means that the drill with the smaller battery “isn't strong enough to drill some holes or drive some long screws” is nonsense. The “big battery” doesn’t improve the quality, either.

By the way, variations far greater than 5% are caused by:

• The generation of the battery.
• The ambient temperature.
• The number of charge/discharge cycles.

So, in plain English, the only real life difference between different ampere hour capacities is the length of time you can use them, between recharges.

This thread is about a DeWalt 18V cordless drill. We are not talking flexvolt batteries, circular saws, world being flat, blah blah blah.
Both in real world use and in theory, and I have experience of both, there is absolutely NO noticeable difference, no torque difference, no any difference between putting a 2 ah battery or a 4 ah battery on this drill other than the 4 ah would run longer and weigh more.

In the video where they benchmark tested the 2ah 4ah and 6ah they recorder 12 percent more torque between the 2ah and the 6ah. They also recorded faster rotation.

12 percent is very noticeable and very real. You try drill an 8 inch hole with a 25mm auger wood drill bit on a fully charged 2ah battery and it will slow down & stop before you get through but a 5ah or 6ah battery will get you all the way through.

I suppose at least the sweeping posts of "all battery torque is the same & it's totally impossible" have stopped so we've made some progress with the thread

I don't know the answer to that tbh. I'd expect the more expensive one to be able to do it slowly. It'll but a lot of wear & tear on a cordless drill drilling holes like that. If it's just a one off job why not borrow a sds mains drill. It'll fly through it.

Back in the day I used to drill holes for half inch pipe through solid walls. Sds mains was the best option. I kept the cordless drill for smaller holes. Now I drill dozens of 6mm holes in tiles everyday with the Dewalt cordless. I don't drill though walls anymore so no longer have a sds drill. Once I got rid of that I no longer needed the extension lead. Now there is nothing in my van with a power cord

I'm looking for a cordless drill for screws but I'm not sure I can justify the price of some of the more expensive ones. I do a fair amount of diy and was making a garden fence at the weekend and it took me 3 times the time it would have taken with an electric screwdriver so I'm biting the bullet. I have a big old wired drill that will do any wall drilling so this will really just be for wood screws.
Saw this advertised in Lidl
https://www.lidl.ie/en/special-offers.htm?articleId=15392
but wonder am I just kidding myself. For taking a door off hinges etc it should be perfect. Its just won't do any big jobs which I might have over the next year or two - taking up a deck etc.
I've had good experience with some Parkside branded tools before so expect it to be decent enough. Will get a few years for €35.
Should I just go with something decent?
