Impact Drivers
 

I see these in the Screwfix catalogue, Impact Drivers. Anyone know what
that is? Does the drill hammer? Is it just a drill/driver without a
chuck? What is the advantage? Also, Drywall Drivers, also in Screwfix,
what do they do over a drill/driver? If a tool can save me time, effort
and produces a better quality job, then I am always interested.

An impact driver is usually a screwdriver which can take a variety of bits
or sockets and has a cam mechanism within. It's purely mechanical. You
engage it on the screw or nut and whack it with a hammer. Most commonly
used on cars rather than houses.

Of course Screwfix may mean something else - if so a reference would help.

If it looks like a miniature grease gun, its a thing you put a bit of
some sort in the front, hold firmly over a nut or screw and whack very
hard with a hammer on the large end.

The wack is converted into rotary motion and combined with the force
of the whack, frees the nut/screw. ( you hope)

It's the equivalent of hitting a spanner with a hammer to shock a
fitting loose (or tight). When the nut/bolt is loose it spins to drive
it, when it's tight it hammers. You've probably seen an air-powered
version being used in KwikFit. The manual version is used with a hammer
- when you hit it on the end some of the force drives the bit against
the screwhead and some is converted to rotation to turn the screw
slightly.

Also, Drywall Drivers, also in Screwfix,
what do they do over a drill/driver? If a tool can save me time, effort
and produces a better quality job, then I am always interested.


Drywall drivers have a depth stop that activates a clutch so you can't
drive screws too far and split the paper facing on plasterboard. The
cheapo version is just a bit with a fixed collar that makes it slip out
of the screw head at a certain depth.

Would you believe it, Richard Cranium hasn't a clue as usual. An impact
driver in this sense, is a drill/driver that has a "rotational" hammer
action. When no resistance to the screw it spins, resistance, and then the
hammer action comes in. The action cannot be turned off, like in hammers
dills. A 12v impact driver can outperform a 18 or 24v drill/driver in
driving screws. They cam be used as drills too, but are primarily designed
to drive. An 18V impact driver can run in a 6" screw without any pilot
hole. Even smaller voltages can do the same. They also don't chew up
screws as much as normal drill/drivers. They are

They are purely professional tools that is why you don't see them in the DIY
sheds. Wickes, who are a professional outlet don't even sell them yet.
They have not been around long and are very expensive with over £200 the
normal price. The cheapest is the 18v Ryobi at £70 with the battery extra
(the one battery fits all system). Two batteries and a charger would be
about £60, making the cheapest around £130, or even cheaper using just one
battery. Because of the hammer action they do not take a lot out of the
battery compared to a drill/driver. They tend not to have a chuck just a
1/4" hex socket for driver bits and drills. Some versions have a detachable
chuck. In the US there is an angled version available, made by Ridgid.

They take a little bit of getting used to but are brilliant when you have
the knack. Stretching out from a ladder, a screw can be driven in with no
problems. If doing a lot of driving, they are the business. I prefer one of
these with a detachable chuck to a normal drill/driver. When the price
drops and the cheaper DIY makes start making them, then the price will drop.

Impact screwdrivers are the business, there are now cheap ones available,
but I haven't tried a cheapy, my one is an ELU that machine mart were
selling so cheap it was ridiculous, I wish I had bought several, but at the
time I didn't realise really what they did!

You need one if you do more than a very occasional diy job.

A review. One Panasonic model is a drill./driver and an impact driver, but
around £450 in the UK. This test rates the Ryobi, which is well priced.

I think you miss the point, these (cordless impact screwdrivers) are
specifically designed for installing and removing screws (particularly
woodscrews) at great speed without the need for pilot holes in most cases.
I also use them on screws on engine cases etc.

The impact driver you mean (I believe) is the sort used commonly for undoing
door hinge screws on cars etc. A better alternative for those is the air
chisel mounted screwdriver. Snap on sell them and they are amazing at
removing even the most horribly rusted in screw (and very cheap!).

The message
from "Dave Plowman (News)" contains these words:

An impact driver is usually a screwdriver which can take a variety of bits
or sockets and has a cam mechanism within. It's purely mechanical. You
engage it on the screw or nut and whack it with a hammer. Most commonly
used on cars rather than houses.

Until drivels brother posed the question I thought such information was
common knowledge. ;-)

Of course Screwfix may mean something else - if so a reference would help.

They do. Page 634/635 of the current catalogue. Not indexed - Impact
wrenches were which is how I found them.

"Impact mechanism uses rotary impacts to generate extremely high torque"
is the description on the DeWalt jobbie. (Only £249.96.) Seems a bit odd
asking the question in the first place when it is there in black and
white but what would you expect from drivels brother?

Whether that is expensive is a
matter of opinion. There are smaller
ones at about £160

http://www.screwfix.com/app/sfd/cat/...81874&ts=57909

That has just been dropped £30

which are quite respectable in terms of performance.

The beefier 18v Ryobi is the better option at that price. After all you
need power with these things. They are primarily design to drive. The
Ryobi
gets good reports.

While I wouldn't suggest that an 18v Ryobi tool is on a par with a 12v
product from a manufacturer, and I would probably say that an 18v
Ryobi tool is likely to have better batteries than a Fermerbauer
Champion Devil; it is not reasonable to assume that 18v Ryobi product
means very much in terms of performance.

Matt, you made all that up.

I see. So nobody else should buy one in that case...

Matt, certainly not you, as you can hurt yourself.

I see these in the Screwfix catalogue, Impact Drivers. Anyone know what
that is? Does the drill hammer? Is it just a drill/driver without a
chuck? What is the advantage? Also, Drywall Drivers, also in Screwfix,
what do they do over a drill/driver? If a tool can save me time, effort
and produces a better quality job, then I am always interested.

An impact driver is usually a screwdriver which can take a variety of
bits
or sockets and has a cam mechanism within. It's purely mechanical. You
engage it on the screw or nut and whack it with a hammer. Most commonly
used on cars rather than houses.

Until drivels brother posed the question I thought such information was
common knowledge. ;-)

seems half you lot are confusing two very different tools, and the intended
use.

since the OP also asked about Drywall Drivers its reasonable to assume the
former.

It is a screwdriver for tightening and loosening extremely tight
screws, often used in engineering and mechanical trades. They usually
take the form of a holder with interchangable bits for different screw
types/sizes. They are designed to be hit with a hammer, when a short
spiral imparts a sharp turning force upon the screw.

Everyone else here seems to agree. Of course dribble doesn't use tools but
only drools over them in catalogues. So it's no surprise he doesn't know
even common stuff.

Of course Screwfix may mean something else - if so a reference would
help.

They do. Page 634/635 of the current catalogue. Not indexed - Impact
wrenches were which is how I found them.

Ah - a very different thing.

"Impact mechanism uses rotary impacts to generate extremely high torque"
is the description on the DeWalt jobbie. (Only £249.96.) Seems a bit odd
asking the question in the first place when it is there in black and
white but what would you expect from drivels brother?

I've got a 12 volt one which runs off the car battery. Can be useful for
some things, although it's really meant for loosening wheel nuts after
Kwik-Fit have been at them with their air tool set on kill. Didn't cost
anything like 250 quid, though.

I think it has been dermined that it is not hit with a hammer as it costs
£250.

You don't have a clue what an impact driver is.

You do not recognize a descriptive and accurate definition, when it hits
you in the face.

Having worked in engineering for over 40 odd years, an impact driver is
as Dave describes. You whack it with a hammer and it puts a turning
motion on the object of your desires.

If a manufacturer wants to introduce an electrically driven one, then
the name should suggest that it is electrically driven. i.e.
Electrically driven impact driver.

Impact means that it gets impacted. It does not specify by what means
the impact takes place. Air driven impact drivers have been in use at
most garages for as long as I can remember, but they are called air
driven impact guns, when described by their Sunday name ;-)

Get it?

Case closed

I know all about mechanical drivers. The OP mentioned drills.

Where?

It happens that Doctor Drivel formulated :

So it seems, but nothing to stop you still hitting it with a hammer :-)

Not so. He mentioned an impact driver and then went onto mention drills
that have impact settings on them. A different thing.

By the way, how old are you?

You should be OK when you are 5 years old :-)

Probably Kress don't have one yet.

Ah that would be it. Couldn't be that Wickes is just another DIY shed

Wickes is geared for the trade. Go in one one day.


I have. They are not "geared for the trade".

They are a linsey-woolsey organisation if ever I saw one - sort of
being a DIY outlet but having a limited range, and sort of being a
trade outlet but again having a limited range of mediochre quality
things - e.g. the timber and the tools.

You had better ask Matt about that.

It's pretty obvious that one major cost element is batteries and the
other is the mechanics and design, material and quality control
thereof.

Given that reality, it isn't that hard to figure out that you get what
you pay for.
