I have a ROK RPCSD 4.8V cordless screwdriver. When fully charged it won't drive a screw all the way into a flat pack where the hole for the screw is already made? Should it go all the way? Goes about 3/4 of the way
 
Maybe it's a not very powerful screwdriver. How much did you pay for it?
My Ryobi one would handle that no bother, assuming the flat pack is laminate chipboard.

I would be able to screw a 6cm screw into a block of softwood where no hole has been made on a full charge.
 
I cannot remember how much it was i think around 25 euro

4.8volts is not a lot.
Your screwdriver has not a lot of torque (rotational force). The higher the voltage, the more torque you have, and 4.8v is not a lot. My cordless screwdriver is 14.4 volts.

On saying that, there could be other problems. Maybe the battery is not charged enough. Also maybe the battery is damaged insofar as it has lost its ability to hold charge.

It could be that the battery is working on less than 4.8 volts if not fully charged, or damaged. You could test the battery with a multimeter.

4.8v screwdriver just aint good enough.. You need a minimum of 12v..
 
Thanks. The battery indicators are showing a full charge. Suppose it could be damaged was in shed during winter ice up and i never really used it before so don't know what it was like pre ice What is a reasonably priced decent one.?
 
Honestly ? A good Bosch Li-Ion one would be about €65.

Even a 9.6v Dewalt or similar would be much more useful.
 
Yes, 4.6V isn't really enough, and ROK are pretty brutal really.

A Bosch or a Makita would work well with only 4.6V, but really you need about 9.6V minimum, or 12V or 14.4V for better results.

The LIDL Parkside tool manuals can be downloaded on
http://www.kompernass.com
You have to choose the language and then the brand Parkside, then look for the manual. The manual might list the torque.. for example, a 14.4 Makita screwgun has a torque of about 36Nm.. this is quite good.. a 6 x 100mm screw could easily be screwed into softwoods using that.

This screwgun
[broken link removed]
on special offer, 70 UK pounds, down from 110 pounds, with three batteries, would be very good and is a professional tool, used everyday all day by professionals.. (torque = 30Nm, should be loads for light-ish work) ... you might not need that quality of screwgun, but it would likely last decades if looked after.

I think the Parkside tools are good, and that screwgun for 20 Euro does look pretty good, and it should handle assembling flatpacks.

It's not recommended to use power tools to assemble flatpacks. If you had the Makita you can specify the maximum power the screwgun should use, so they can be used safely as the power can be turned right down, and you finish tightening each screw by hand.. no risk of damaging the cabinets. The LIDL Parkside one is incredibly cheap, at 19.99, for a 13.6 Li-Ion screwgun, with 26 bits. Li-Ion is the best battery technology available, within reason, maybe NASA have better batteries for spaceships or something but Li-Ion is very good. The LIDL one also has a 'clutch' which allows you to specify a lower power setting to avoid damaging workpieces.


Crap batteries will discharge over time by themselves... this can be annoying for DIY use, as you have to remember to charge up before use.

Cheers so

Might seem obvious but 'some' of those screws in flat packs are only meant to go in some of the way....up as far as the collar on them.
 
I have the cordless drill at
and it drives the screws but I only have the one screwdriver bit that came with it. The bits from the ROK are too short. Will I get longer bits?

Out of curiosity I took a screw and tried to drive it into a piece of batten with the ROK. Went a couple mm. With the Tesco cordless drill I drove it right through no problem

The ROk is useless how can they sell those? Are they meant to just start screws to hand finish?
 
lets face it , when you bought it , YOU got screwed
 
it does raise some issues, like fitness for purpose. It shouldn't be legal to sell an item which can't do its job even when new and in perfect condition, but some of those cheap tools are like that.. it's not just that they're bad, they just don't seem to work at all.

It probably is illegal, as items must be fit for purpose.
 
@sustanonThen why does the other cordless drill drive the same screw through the same wood as if it were butter?hOH I see what you mean now, you are referring to to my op where i was driving to a ready made hole. See post number 11 where i compared it with the other drill/driver
