I used some green Bosch tools for years on site work. They are by far the best for the money. They even outlasted my expensive Dewalt stuff. The blue Bosch tools are better again.

That drill will last a lifetime for DIY use.

I had a PSB700RE some years back, possibly the best drill of its class I ever used. That's a fantastic price for that.

Someone over on the HUKD site commented

"If it's not SDS it's not really any good for anything but very light work".

I don't know anything about drills but does anyone have an opinion on this?

It may take more effort to get through hard concrete Its no SDS drill for sure, but SDS it a very clumsy hard hitting tool. They pound the drill bit hard which is good for some applications but not all.

Say you wanted to drill a hole in a floor or wall tile. The bosch will do it accurately and without damage. And SDS would probably smash the tile before the hole was drilled. Same as hanging a picture. The sds has more chance of cracking the plaster on your wall. Thats why SDS is usually for the trade and not DIY.

Ive never found SDS to be any more harsh on the material unless its in hammeraction of course

Max torque 9 Nm? This is not much better than hand crank drill!

For comparison 18V Bosh Cordless Hammer Drill has torqe 48 Nm

That is twisting force, a electric drill is rarely used for screws so twisting in not required.

Surely you don't think that the 18V cordless would be more powerful that the OP link?

Surprisingly I do. Just read the description, before posting. This one: Torque 9Nm. Drilling capacity for wood 30mm, steel 12mm, masonry 14mm

18V cordless: Torque 48Nm. Drilling capacity for wood 35mm, steel 13mm, masonry 15mm

So, which one is more powerful in your opinion?

Power wise, the corded without question. For convenience / driving, the cordless.

It's 3 times the price? Whats your point?
Do you know of a comparably priced cordless drill with similar power?
If you do then link it.

ecomac

@dodzy You can't argue with numbers. Oh, sorry, obviously YOU can. And the Earth is flat, if you only say so. In this case I rest my case.

asharkman wrote: »

My point is to bring potential buyers attention to the technical specs of this drill. Comparing the specs, not only the price may save you a dissapointment.

Firstly, torque and power are not the same thing. It is entirely possible for an electric motor to produce more torque than a big-block Dodge while doing precisely nothing. Power is torque produced at a given rotational speed. You'll find these high-output Li-ion cordless drills spin at half the speed or less of their corded counterparts.

Modern batteries are excellent, and they are somewhat more powerful RPM-for-RPM, but I'd like to point out that 48 Nm is about half the torque of a 1,340 cc Harley-Davidson, and 9 Nm is not atypical of a corded drill of that class and is perfectly adequate for anything shy of boring ship's hulls.

Hmmm. I take it you mean a bit-and-brace? Let's have a look. 9 Nm is ~6.5 lb. ft. - indulge an oul' fella. Assuming our brace has a crank-throw of three inches, we therefore need to apply a "pull" of just under two stone (26 lb.), constantly and at a tangent perpendicular to the throw-radius, and all at a decent speed. I suggest you try it!

48Nm/2 (by 2 as its only a half of the speed of corded drill) = 24Nm compared to 9Nm.

It seems that you have really taken it seriously :eek:, haven't you?

I think this tread badly needs a moderator. Will not argue any further on this subject. If you need a cheap drill, get it. If you need a good one, don't. End of story.

I'm not arguing! I always take torque seriously, though.

In fairness Eco, Jim is merely pointing out the differences between what you believe to be true and fact.

Put simply, there is no comparison to be made between your link and that of the OP ( and that includes the pricing ). This is a genuine BA in my opinion, and should be left that way.

I certainly think so. I have a 710W B&D corded yoke that I picked up a couple of years ago for €46. It's rated at 4.5 Nm, and that is plenty to go through concrete block walls like they're not there, and to reduce a cobalt-steel HSS bit to slag due to my running it too fast with no oil!

bmaxi

Looks like a pretty good deal to me. To compare corded and cordless drills on a like for like basis is not feasible. It's not comparing apples with apples.

brokenarms

No expert on torque , but is this figure simply down to gearing?

The corded drill will spins much faster which in turn(pun) will produce less torque.

Thanks OP.
I got the last one in Dun Laoghaire today.

I also picked up this too:
<http://www.argos.ie/static/Product/partNumber/7003677/c_1/1|category_root|Garden+and+DIY|14418702/c_2/3|19805469|Power+tools|14418763/c_3/4|cat_14418763|Drill+bits|14418772.htm>

It's down to €13.19, but when you buy it with the drill, you get another 50% off.
So I got the drill and bits for €46.58

Happy Days

This deal is back on. Picked one up in Drogheda.
