IR 2125 QTiMax questions

[suresnoi]

Hi all,

Ok so the 2125 QTiMax is the little brother of the IR 2135 QTiMax which is known, among a few others, to be unstoppable when working on a car. AFAIK there is nothing on a car that a 2135 won't break loose.

The 2125 is ratted for a little less than half the power of the 2135.
-> 332 ft.lbs of max torque in reverse vs. 780ft.lbs for the 2135.

Now my question is, what kind of stuff found on a car won't the 2125 break loose ? assuming a good air supply. What's the point of keeping a 2135 if one gets a 2125 ?

My second question is : why would someone want to get the 3/8" version of the 2125 over the 1/2 version ? From 16mm and up the OD of the socket is determined by the bolt size, and below that, the OD will be smaller on 3/8" sockets but how significant is that ? I would lean on the 1/2" size for square drive toughness but could this be the wrong call.


Thanks for your advise
cheers!

The 2125 is just a 2115 (3/8" version) with a 1/2" anvil. It has a lot of power for a 3/8" gun, but not nearly as much as its big brother. I have a 2115 and a 2135 and no use for a 2125 as my 3/8" impact sockets go up to 24mm.

Not really much use in a compact 1/2" impact gun. Don't go thinking it could really be used in place of a 2135.

crank bolts takes a lot of balls to knock loose in may cases

i also have a 2115qtimax. And as long as you have a perfect air supply it can do most things you need an impact for on a car. The only thing i would not expect it to pull off are crank bolts, maybe axle nuts, maybe some large very stuck suspension components too. I'm not all that sure because I've always had my 1/2" gun and those kinds of things are so large that they use 1/2" sockets anyway so there's no point in trying to make my 3/8" work. I just go straight to the 1/2".

Air supply is key. At work my 2115 is up to its potential and my 2135 isn't, due to crappy air supply. The 2115 is great for most work, but won't always remove wheel nuts/bolts, crank bolts, hub nuts, large chassis bolts, etc. For most work it's great.

if you swing the proverbial wrench for a living - meaning you have an impact wrench in your hand for hours, every workday..you'll appreciate the lightest / most ergonomic tool that gets the job done. as far as the 2125 goes, i don't know what question it is the answer to. i'm a fairly heavy hobbyist - and recently started using a 3/8" nitrocat impact instead of my IR 1/2". it handles 95% of the fasteners at less than half the weight. its composite, so it doesn't turn my hand into an icicle. and when i need the oomph, i plug in the 1/2.

probably MORESO as a hobbyist, i appreciate the light weight - i've found my hands noticeably less sore in the days after spending a lot of time in the shop. the biggest 'downside' to using the 3/8 is that i essentially had to re-buy a bunch of sockets in the proper drive. but no one here really thinks thats a downside, do they?

ahm

I have both. I use the 2125 as a lightweight 1/2 drive impact. It's perfect for lug nuts. However, it's really a 2115timax with a 1/2 drive anvil so, it lacks power for some suspension work and removing brake caliper crossover brackets or stubborn engine work. I'm old and lazy so, i like the light package the 2125 affords me at the end of a long day. However, if needed my 2135qtimax sits within easy reach on my cart. It's not an either or prposition but, the 2125 compliments the 2135.

rusty suspension bolts on pickup trucks or cars. anything in the rustbelt can get pretty tough after a few years

Guys,

Thanks a lot for all the input, it's all I needed to know

Cheers!
