Just as a sort of reminder to all...

I recently purchased a Makita 6980 FD
Cordless Impact Driver. It really is a
super bit of kit.. However.. a small safety
warning....

I have had two screwdriver tips shatter ..
The last bit broke off and hit the
face mask I was thankfully wearing
traveling a some speed.

So, this will never happen with quality bits?
And what about bits of the screw?

Hmmm - perhaps -

The bits came with the Driver - Makita bits..

What would you recommend?

While I don't agree with the notion that better bits will necessarily
last longer when using an impact driver, I do think that a lot of
bundled Makita and DeWalt bits are of quite poor quality.

I have several sets of Wera bits, and have been very impressed with
them, they seem to last a very long time.

Grunff,

Many thanks for your help...

Yes - good thought - I have some Wera screwdrivers
and they are very good...

I believe the bits do need to have this sort of shank,...

http://www.gillandroy.com/diy/odds/impact/shank

I expect Wera do this sort of bit - I will follow up on this..

Thanks,

Either the bits or the holder - my Wera sets have bit holders like this:

Unfortunately Makita, Bosch and DeWalt all supply pretty mediochre
bits in their tool bundles. Rather stupid really because they let
down what are otherwise excellent tools.

The only screwdriver/drill manufacturer that I have found who does
supply good quality bits with tools and separately is Festool.


In terms of good quality screwdriver bits, I tend to use products
made by Wera and Wiha.

Having said that, I wonder whether using Pozidriv screws is a good
idea with an impact driver anyway. Cam out is a problem with them at
the best of times and nurges the bit as well. From the photo, it
looks as though that had been happening before the bit broke.
Adding impact driving to the mix makes the effect worse.

Generally Torx screws and bits seem to work a lot better from the
perspective of avoiding camout. I tend to use them for most
purposes now, although I haven't tried them for impact use. Might be
worth a try.

Yes - I think I agree - Posidrive + Impact driver probably not a good idea.

Definitely Posidrives need a nice even torque, just enough to drive them
in.

'Nurges'? Is this a technical term I'm unfamiliar with?

:-)

It's a word I've always used (as in nurged up) for things like
stripped or crossed threads, cammed out screws that can no longer be
driven either way, basically anything where there has been some
mechanical effect that prevents the item from being put in or taken
out.

Another typical example is where you change a float valve for one with
a plastic thread. The right way to do this is to get the nut of the
tap connector on with the back nut that holds it onto the tank/cistern
loose. If you do it the other way, Sod's law dictates tha tthe
plumbing won't be well enough aligned and the tap connector nut will
go on cross threaded. There is more than an even chance, if you are
heavy handed, that the thread of the valve will be nurged up.

The effect can be compounded of course because typically then
something heavy/rough/risky is going to have to be used to get the
thing out or put it all the way in

This is a usefully inoccuous expression that you can use in the
presence of elderly spinsters when you are fixing their plumbing and
something bad happens. Of course, they might ask you whether you
f*cked it up, but then at least you know where you are. :-)

Forgive my stupidity, but from the subject line and post content, I get
the impression the screwdriver bit is being used with an "impact" setting.

From my years long gone by, an impact driver was a fat bodied
mechanical device operated by a sharp blow with a lump hammer. The only
things used in an "impact wrench" (CP Air tools) were 6 sided impact
sockets.

I can't see why there would ever be a requirement to use an impact
setting on a screw. All sounds a bit dodgy to me.

Can someone enlighten me.

.......... on reflection.... I have a vague recollection of stuffing a
cross-head screwdriver into a 12 sided socket used on said air wrench to
fit new bed-boards to a lorry, though this was purely due to lack of
cordless driver technology in those days.

TIA
Pete

Yes, this is an impact driver:
http://www.screwfix.com/app/sfd/cat/...16735&ts=72305

But more recently, these have become known as impact drivers too:
http://www.screwfix.com/app/sfd/cat/...57026&ts=72305

It's basically a battery powered, rechargeable version on an impact wrench.

The reason they're used for screwdriving is because they can deliver
huge torque (albeit pulsed) compared to the same size/weight cordless
drill/driver.

My query though is, if a regular screw (philips/pozi etc) needs more
torque than can be applied by a regular combi/cordless driver there is
surely something wrong.

Looking on t'internet I see a benefit for driving coach bolts etc but
not regular screws.

Would they?

The ones I have seen have a taperd shank, so as the bolt goes deeper,
the rqd. torque increases but the shank is thicker and will handle
increased loads.

There are four benefits, such that since buying an 12v elu off ebay
three years ago I would never (unless stuck up a ladder with a
drill/driver) choose to drive a screw with either of my cordless drills
(14.4v and 18v). First advantage is more power for really big screws
or coachbolts, or just more speed with any else. The second is that
the impulsed nature of the power means that there is no torque
reaction, so it doesn't try to twist your wrist off no matter how hard
it is working. The third is that you don't get cam-out, ever -
although it does eat bits, especially rubbish ones, I've never had one
explode like the OP. The fourth is that it is far far more
controllable, so you can guage the speed and depth to which you are
driving much more accurately.

I can't see how anyone who has ever actually used one could not
recognise that they are utterly superior for driving screws - the
difference is night and day.

Sorry if this posting is munged - using google while I find an
alternative newsfeed thanks to my ISP terminating its provision.

That's prolly just it, I had never heard of them let alone used one.
