24v 'Rattle Gun' not using air ?

[ng_newbie]

I would like to have a 'rattle gun' that runs on 24v DC.

I know that you would run a compressor in the workshop to use a rattle gun, but I don't want to buy a new compressor as well as the gun.

Not ever certain if I should be searching for "1/2 Drive Impact Wrench" or "?" ...

Anyone go any ideas for me ?

24v?

Is it a cordless thing you are after or something to run from, say, the cigarette socket in the car?

Google search for "24v impact wrench", there are plenty out there.

Why does it have to be 24 volt?

these go all right buy a milwaukee and charge it of your battery pack?

Because 1 of my neighbour was a trucky and he says that 24v make 12v look like toys

I watched this video and it is 12v not 24v, but still interesting that 12v wrench can handle wheel studs thanks, not certain they are 4x4 studs

Has anyone else noticed that 12v cordless has gone to 18v +++ ?

Checked out a rule called OHMs today and a 24v over 12v means less resistance, so over the same cables I get twice the watts.

volt drop matters pretty quick on a 12 volts once the distance is more than a meter or 3 when drawing lots of current

I've been looking at Rattle guns, Tech Guns, Mini-Blowers and Battery Drills. All in the same brand so I can interchange the batteries. 18V is the current Battery Operated Tool nominal voltage and as someone has already pointed out, the "Old" truckies would sometimes have a 24V (Leaded) rattle gun to help them out sometimes. They could clip it onto their truck batteries and get the job done. These days the 18V gear will do the job, just be careful of which brand you pick. Ozito (or cheaper units) will be fine if you're driving a corolla. Milwaukee, Hilti, and a few others are the top of the market and will do the larger vehicles 4X4s etc, maybe even larger trucks. I dunno. There's a myriad of in between brands as well.
The skin will usually do you fine, it's the battery you need to look at AND CARE FOR.
"Look at" how many milliamp/hours the battery is rated at. The higher the figure the better battery capacity you'll get. Using Aldi only as an example here: They put out a 2mA/Hr and a 4mA/Hr battery for their gear, 4 will last you longer than the 2 AND provide slightly higher torque from your tool for a while.
Other brands have batteries that go up to 6, 8 and maybe even higher mA/Hr ratings.
Once you've bought it, remember to look after your battery, leaving it sit in the recovery tool box until you need it in 2 or 3 years time is not looking after your battery.
Do your research and have fun out there.

Oh, small footnote, the Ohms Law calculator is from AS3008 which is for fix installation wiring used by electricians. I feel certain that the Australian Standard for automotive works will also be available on the Standards web site, but I don't know which standard number it would be.

if you want to undo some of the Toyota tight bolts on the hilux a cheap rattle gun is a waste of time.
Ive fried more than one winch putting 24 volt onto it. If you have daul battery's its pretty easy to get 24 volts to the winch.
The rattler I linked to above will undo the balencer bolt easierly and probably break wheel studs if you tried to.
The volt drop calc I linked to will work fine when set to 12 volt dc. it may be handy if you wanted to use 40 amps over 5 or 6 meters in selecting a cable

[hiluxxury]

I have this https://www.dewalt.com.au/products/dcf8 ... -bare-unit

I use it to undo the CV nut on the front hub. They claim its good for 1625nm and I don't doubt it. Its big but I can throw it into my tool kit with only one 5ah battery and not worry about any nut being hard to undo or it running out of charge.

[bob14hilux]

Voltage drop over your length of cable is not really relevant when you are using cordless tools

it may be handy if you wanted to use 40 amps over 5 or 6 meters in selecting a cable

Just remember the cables in the calculator are measured in square millimetres. This is a cross-sectional area (CSA) measurement and NOT simply the diameter. I'd actually like to know if Aust Standards have a calculator for translating CSA to / from a cable "Gauge" that seems to be commonly used through the Auto-Elec industry.
Maybe One Day.

as3008.1 wont have a converter as every cable rated to 600 volts will be sized mm2

So cool, thanks Steve

Guys

I said 24v in the subject, yes I didn't say 24v DC, I appreciate you replying, but I don't want to use cables.

If I can get away with it, I would be happy to never run a cable more than 1/2 Mtr. again.

So the point of this post is?
To spam your battery link? Do you want to waste more money on an inverter now?
Most blokes find the appliance they want to run then build a suitable power supply.

Steve

You are assuming everyone is like you !!!

I was told to look for 'next gen.' cordless tools not toys

trucks have been using 24v D C for years.

So the point of this post is?

To see if someone has already 'solved' this problem

To spam your battery link?

I was told spam is email, this does not make any sense to me

Do you want to waste more money on an inverter now?

I have not wasted 1 cent

I'm not going to because other poster have given me some g8 info. as I already have dewalt tools ( a few batteries ) I have ordered 1

Most blokes find the appliance they want to run then build a suitable power supply.

So you say expert

[ng_newbie]

Hey hiluxxury

G8 reply

I have this https://www.dewalt.com.au/products/dcf8 ... -bare-unit

Thanks for the link I already have Dewalt so you experience with this helped me heaps

[hiluxxury]

No worries, its overkill but i needed it for my hub nuts that had rusted on a destroyed 3 breaker bars.

This thing undid the nut like it was a 10mm tightened with my fingers. I was blown away. It does wheel nuts for days on a 5ah battery
