Impact driver help

A manual impact driver requires you to hit something hard with a hammer, if that something is in a weak structure you might find that you've just removed said screw/bolt/whatever by driving it straight through the body of whatever the bolt/screw/nut/whatever is in. Electric is basically the same mechanism as a hammer drill, a couple of spring preloaded ball bearings stop the bit from spinning and that impact is the impact you're using to undo the screwboltthing.

thanks for that
im still unsure
would an electric one be able to undo the tightest of screws on a bike?

Screws or bolts? The one I posted up a while ago goes upto about 100Nm but I'm a bit skeptical about whether its really capable of smashing that out, but if it did 10% of 100Nm it would still be pumping out a few multiples of the maximum you'd ever achieve with a screwdriver.

screws
i don't think theres any bolts on a bike, a long breaker bar cant undo?
the thing with the electric ones is that they cost quite a bit
might be out of my budget, but seeing that i have no jobs to do right now, i might wait and save

I think you are getting bolts mixed up with screws. There are hardly any screws on a bike, mainly bolts.

Also go the electric one over the manual.

you mean, mainly bolts

id seriously suggest an electric one, i had both the sump bolts on my bike done up by a shop after the first service and i ended up having to use a manual impact driver to get the off. really not a fan of em, ive used electric in the past and it felt much much better

Oh ffs now he's got me taking retarded. I'm editing my post now.

no i was talking about screws
there's a fair number of them very tight in places
like the ones on the carby
seemed like they were superglued to the carbs

i know the difference between a screw and a bolt

im not looking for an impact driver for bolts, i dont think you can even use an impact driver on bolts, unless you cut a groove in it
what i need i something to undo tight screws which won't chew them up
the last owner really fucked up some screws on my bike

Bunnings > ozito brand, has a 1/2" socket head. ~$79 I think. Bargain imo.

However, with a screw especially a carby one you will more than likely round out the screw head whether its allen or phillips with a rattle gun. Getting an extenion arm on an allen key might be a good idea.

If it's a phillips head then the hammer impact driver might be the go as it forces the screw head into the screw and saves damaging it.

is that a manual?
coz theres a kincrome one for 65 bucks

my carby has phillips heads, 80% of them were chewed up thanks to the last owner

i think i'll probably end up getting the manual one coz most people above thought i was talking about bolts for some reason
i wasn't talking about a rattle gun, i was talking about something like a drill which uses phillips head and slotted pieces for tight screws

Your were talking about an electric drill. They might give you the torque you need but not for the budget you want.

The thing I described is an electric rattle gun. Great for all things socket tight... ie front sprocket nuts etc.

Rattle gun is a coloquialism for a powered impact driver

You just have to get the correct impact bits to deal with almost anything with them.

FYI I've used my little electric impact driver on badly stripped carby screws among other things, all you've got to do is apply a bit of pressure to help the tool bite, then it will rip em right out.

i know what a rattle gun is and what it does
rattle gun is used for bolts only, unless they have an adaptor for it, which can then be used for screws

dont really need a rattle gun coz i haven't encountered any bolts i cant undo with a breaker bar

well if it does work on badly stripped screws, then i might consider the electric one

This is the one that I've got, I've entertained the idea of buying a bigger one to go with it, but this certainly does the job for most things.

I paid about $35 for my mechanincal/manual one.
Works a treat.

drew, yeah was looking at that one
then saw the price and immediately closed the page

yeah i'll probably end up getting one of them
and just to be on the safe side i'll get kincrome
its about 20 bucks extra but worth it imo for something your gonna hammer a lot

haha yeah, i actually look forward to those really tight bolts
for some reason its just fun undoing tight botls with a breaker bar

+1 for Smiley's pic. The nice thing is that you can often just use it as a screwdriver. The larger handhold (since it has such a large diameter) helps you get better grip and the stubby body allows you to put some force behind it.

Theres a mob in the UK selling one for $230 with batteries and charger... I'm pretty sure that I bought mine from some people in sydney with an angle drive drill and a torch for about $300 though.
