Re: screw driver attachment on drilling machine?

You've still not really described what's actually happening. Is the drill (machine) turning? Is the screwdriver bit turning? Is it just jumping out of the screw head itself? Is the screw turning but not penetrating?

I'm frankly struggling to work out your problem, from what you've said so far.
yes, yes, yes but not because it's the wrong attachment, no.

If I understood my problem I would not reach out.

it takes more power to drill holes into concrete than screwing a screw into wood.
Depends, a 6mm hole in concrete is easier done, than a 6mm screw in proper hard wood.
Quote:
It makes a lot of noise but doesn't drill the screw in.
Options:

- A button is not in proper position, thus the gears in your machine might not touch each other properly.

Easily tested. Hold the machine in your hand and press the buttons to see if it spins normally, if so that should be o.k.


- Your machine lacks power for the job.

Do you feel the machine delivering power, as in does it want to spin around itself when holding it in the screw and you have to hold it? If so it simply lacks the power for this job. If you lack a setting to increase power do it by hand or buy another machine.

- Machine is broken

Remaining conclusion.

what's the difference between rpm and torque range?
rpm is a measure of how fast the drill is spinning. Torque is a measure of how strongly it is twisting. Think of putting a screw in manually - you might manage 60 or so rpm, but as it gets tighter, you have to apply more force. That force is the torque. If the torque is too low, you'll never get the screw in tight enough - the drill will either stop, or spin out.

Not all drills have torque ranges. Most will have rpm ranges.

Setting on hammer-drilling?
No. Never.

When I built a stage set, we got through 3 screwdriver bits. So have a spare to hand if you're doing a lot of screwing in one session. (fnarr, fnarr).

Re: screw driver attachment on drilling machine?

The lack of power could be a thing. Takes in 500W, gives out 260W - that's definitely more than I can produce manually though.

It's definitely meant to be able to screw. Up to max. 6mm screws according to the manual - yeah, I actually took out the manual. (All the screws today were smaller).

A new set of screw driver bits might do the trick.

Thanks for all the info! I'll report back.

You can very easily notice it that's the problem, than the bit turns around over the screw.

Can be solved by a better bit or pressing harder (or a combo to those two)

Truth be told, that's really not that much. I have a collection of machines and one of them is a 800W, still If I would use it to screw in very hard wood it can happen that I'm just holding the machine while it heats up and either nothing happens or the screw might break, but it won't go in. A 500W I would not even want to use on hard wood.

Re: screw driver attachment on drilling machine?

You'll never screw-in with 500W hammer drill in hardwood, it will just stop and burn, is no enough torque in that thing. First of all, you have to predrill a hole accordingly to the size of the screw, if the screw is 4mm thickness, drill a hole of 3mm. Secondly use for wood PZ2 bit and screws to suit that bit, which will improve the grip.

Re: screw driver attachment on drilling machine?

Maybe the world spins in the opposite direction?

Haha, this is near-impossible to diagnose remotely from your text description, surely you can see what the problem is better than the rest of us? But as Flying Kite suggests, you might need to pre-drill a small hole for the screw if it's a genuine tropical hard wood rather than pine, larch etc.

Or hacksawing a new channel into the screw head.

Just a thought. Dedicated electric screwdrivers are available... Cost around 50 francs.

Not so. I was screwing into 26mm solid oak last week with the weedy little cordless electric screwdriver bought from Lidl a few weeks back. I can't see the power rating, but at only 4V it will a lot less than 500W. Absolute no issues with it, even when using the 90deg angle attachment.

The key is to nake sure you have the correct screwdriver head, especially to be certain you're using Pozidriv bits for Pozidriv screws, and of the correct size. Mixing Phillips and Pozidriv is a recipe for knurled screw heads and damaged bits together with unsuccessful screwing.

Edit: For anyone struggling with crosshead screws of either variety, I recommend moving to Torx screws and bits instead. A much more positive interface, also allows you usually to fit the screw onto the bit and place it hands free.

(And I don't know why you mention the hammer function, which would certainly not be relevant).

ALWAYS drill a hole first.

Naah. As long as you're not near enough an edge to risk splitting the object piece, screwing into solid wood (or MDF and similar) does not normally need a pilot hole.

Just to be clear, unless the drill (we use the word to refer to the machine itself, as well as the drill 'bit') is failing to turn that is not the problem, no amount of power, or torque (which is anyway a function of power) will make any difference.

See my other post for more specifics on the screwdriver/bit interface. It sounds like this is your problem, so using the correct bit, and applying enough pressure so ensuring the bit doesn't jump, should be the way forward Oh, and throw away any screws that you've already been trying with - once the bit has spun in them they'll be fsked. Buy new screws if you don't have enough, rather than reusing the dodgy ones you've already failed with.

I can definitely sympathise. I'm glad my OH is an engineer and I always have a technical consultant so to speak..

If nothing from what the kind EFers suggested here works, I think you could take the drilling machine to the/a shop that sells it and ask one of the staff there. I had many useful conversations with sales people.

Yes. As far as I can judge that it sits tightly


That would be a Schlagschrauber in German. So I should have set the machine on hammering/stone walls?

That takes special screw, right? And doesn't really screw them in but bolts them in?

Edit: When I study this, I should set the "Drehmoment" on highest on my machine.
What do you suggest then? (Cheap, I don't use these things daily).


Yeah, that's the first I do.
no you don't want the hammer function. (an impact driver applies the impact rotationally, not longitudinally like a hammer drill)

it sounds like the drill is spinning too fast and the drill bit is not locked into the screw: probably best to reduce speed to minimum and ensure that you are pressing hard into the screw so the drill bit doesn't slip out.

best thing you could do is throw away your screws and buy Spax screws with their torx-like head. much easier to use and avoid cam-out.

if the drill bit is camming out of the screw, you probably anyway destroyed the screw head or drill bit.

Re: screw driver attachment on drilling machine?

Cordless drill - just the right power with variable settings for screws. Sometimes a really tight screw will need a manual tweak.
Power drill -overpowered for screws, but can be used with a "light touch" and speed setting on lowest available.

and if you are using shitty PZ1/PH1 screws forget about using a drill to drive them in. they're going to cam out and strip the head.

'Come' out, I assume you mean.

Anyway, not necessarily, but certainly more likely in unskilled hands...
