Most people who used 1/4" used similar to this type of deep impact socket

That's a 1/2" drive impact... not sure what your getting act. Impact or chrome, deep or standard won't change the torque value. Impacts are just beefier to withstand the abuse. However I've been known to use chrome sometimes with 3/8" impact guns... sometimes you just gotta get a job done.


Deep means more surface area which allows more torque.

Test it yourself best advice I can give.

I will try this myself when is time for a tire change.


I don't need to test it, because I know what I'm talking about… sorry. Either way, I used a DEEP impact in my testing anyway. Short/Deep, Chrome/Impact DOES NOT make a difference in torque applied. However each has its purpose.

A whole lot of confusion present here with impact drivers and impact wrenches.

Here is Wikipedia on Impact Drivers
https://en.wikipedia.org/wiki/Impact_driver

Impact Wrenches
https://en.wikipedia.org/wiki/Impact_wrench

The cordless impact drivers mentioned in this thread are impact wrenches in that they only apply rotational forces to the fastener.
The terms are commonly used interchangeably.

As per the Wikipedia definition, impact drivers also deliver an axial force and is a specialized tool, not commonly used. Motorcyclists are familiar with the manual impact driver (mentioned by Ducked in a previous post), a very necessary tool when working on Japanese bikes.


Correct, like you said in the US the terms are used somewhat interchangeably…. Hey we're funny like that. Personally I never called it an impact wrench, either: impact, impact gun, cordless impact, impact driver.

Impact drivers are really good with phillips, flat, torx or other "bit" type fasteners… since the axial force (striking of hammer) helps keep the bit from slipping. I'm sure they also predate electric/air impacts. Nowadays, most fasteners that might require an impact are hex, XZN, allen, etc… electric/air have gained popularity since that axial force isn't necessary with those types of fasteners (inherently less slippage) and its more convenient.

However, there's always a place for impact drivers… motorcycles (and JIS fasteners), some JDMs use phillips to hold rotors onto hubs, etc… We have one at the shop, but almost never use it (mostly work Euro stuff). At home I use it from time to time on my motorcycles.

Never seen one that has that much torque.

Are you sure those ain't inch/lb?

This is what I have. I bought the bare tool version though. I could have sworn the torque was 725 for the half and 750 for the 3/4. And I paid 220 for just the bare tool. I already have several Milwaukee m18 tools including an impact drive that I use a lot for automotive also.

Impact driver - hex for household and carpentry work
impact wrench 1/4, 3/8, 1/2 square for mechanical maintenance
impact gun see above; air impact gun is the most common one
impact ratchet (also called reaction less) 1/4 or 3/8 square, shaped like a ratchet and tries to have low profile so can be used in tight spaces; usually torque is limited to 50 ft-lb

Do you have both? If you had both would you still use an impact driver for mechanical work.

I have come across rusted nuts on trailers and my Bobcat that would not loosen without soaking with PB Blaster and trying each day for 3 or 4 days until it came off. So I need the impact wrench anyway. If I need an impact wrench why bother with impact driver. My Milwaukee impact wrench has a low torque setting in addition to the high torque.

Yes I have both and yes I will continue to use both. I don't think I am going to use the 700 ftlbs impact wrench on 1/4" bolts.

Why not, for 1/4" drive sockets or bits… that said, there's a thousand ways to skin a cat. Some guys like to zip all kinds of small fasteners with those 1/4" drivers…. personally I'm in no rush, so I tend to just use ratchets or wrenches. On some bigger or rusted stuff an impact 3/8" or 1/2" is just convenient.

It's the same with air ratchets… it just speeds things up. But sometimes you lack an air supply, sometimes you need to get into tight spaces, sometimes its just tiring working with them (vibration, weight and noise)… everyone has their preferences. Some just use an impact to tighten hardware, they have a feel for it and its quick. Generally I only use an impact to loosen things and finish by hand or torque wrench.

My dad does it for a living… so he uses a lot of air/cordless tools. Its quicker and less laborious, but there's always a place for regular ratchets or wrenches.
 
I use the 1/4" drive Makita with 1/4" sockets all time, it works perfectly for transmission, oil pan bolts and other small fasteners around the car.
It zips them out with ease and runs them up with little chance of over torquing them if you stop at the first sign of a hammer.

The 3/8 drive is good for small stuff all over the engine. The Makita 3A 18v Li batteries have been stellar performers and are still good after almost 7 yrs (maybe 8) yrs of constant use.
I have 4 batteries and not one of them have run down or died, I cant say the same for Milwaukee.

I gave up Milwaukee not because they are bad tools, they perform well but the batteries are the worst in the industry and their CS sucks beyond belief.
I had a problem with one Hilti battery that was a short time out of warranty, they sent not one but 2 with a new charger overnight express. I called them at 2PM and 10 AM the next day the UPS guy was on the door.

I use air ratchets for bigger stuff in tight spaces and anything over 10mm (thread diameter) bolts gets the air impact.
 
While I've had good success with Makita tools and their performance, they warranty service lacks. In the past two years I had to warranty the same drill twice, it needed to brought to a service center and I waited over a month. This time, after a LONG phone call they sent me a shipping label. However I'll still be out a tool for a week or so.

I cannot say for other cordless impacts but the Milwaukee has a very low setting in addition to the 750 ft lbs.

100ft pounds. Still way to much for a quarter inch bolt. Plus the thing is heavy where the driver isn't.
 
I sometimes do road service calls (jump start, tire change, lockout) on bad weather days. I have had very good service from a Craftsman 19.2v impact wrench.

https://www.amazon.ca/Milwaukee-2663-20-...s=impact+wrench

229$+90 for battery and charger 475 ft-lb


about 5more I didnt list.





cheers3.gif


I was hoping to get the same 700 ft/lb


Probably could for 300$~~ish American. so 400$CAN

That 475ft-lb Milwaukee +battery+charger is 242$ US

so that + some import and shipping.


if I were to drive to the USA then come back it would be ~ $300 CAD

http://www.homedepot.com/p/Milwaukee-M18...62-20/204410436

or Splurge on a full set

http://www.homedepot.com/p/Milwaukee-M18...63-22/204410433

1000ft/lb

USA always get the better deals.
