Bosch 182 brushless impact

[JHZR2]

Saw this at lowes today. Goes by various versions of the model IDH182.

It's a 1/4" impact driver, but smartly, rather than just a hex with some round outer ring, the outer section is 1/2" square. So it can take sockets and be used as an impact gun.

At 1650 in-lb, which is like 137 ft-lv, I doubt that this will easily remove lugs torqued to 80 ft-lb with a lite corrosion. Still, it is pretty awesome in terms of its utility.

How are bosch real 1/2" impact guns? I just got an M18 fuel kit for Christmas, so I'm not in the market, but this bosch with that capability really struck me as ingenious, especially if their big impacts and other tools in the 18V system are good. I've always been pleased with my bosch tools.

I have the brushless impact IDH182, as well as the larger proper 1/2" impact (brushed) HTH181 from Bosch.

The IDH182 will remove lug nuts torqued to 110Nm, tried it with a friend's Corolla who came to have his brake pads inspected. It will hammer on the lug nut for 4-5 seconds before successfully spinning it off.

The larger HTH181 takes less effort, hammering for 1-2 seconds before spinning the lug nut off.

If you got the M18 Fuel high torque impact wrench, you got one awesome machine.

Impact drivers are mainly used by carpenters for driving screws. Impact wrenches are for mechanics.

^yes, but the beauty of the bosch unit is that it is set up to do both in one compact tool. Very nice.

Just going off experience with my old IR 360lb-fr gun on come corroded lugs, the little bosch may not cut it. For other stuff, it may well...


It's a great idea. I hope all vendors come out with such a design. I've always been happy with my bosch stuff.

It may not take lug nuts off but a small 1/4" impact is a god send, it is definitely one of my favorite tools.
There is nothing better for removing transmission pan and engine oil pan bolts and its controllable enough to run them up with without generating too much torque so they can be had finished tightened.

Engine covers, valve covers, upper plenum's, almost any smaller sized fastener is this tools forte. It really helps with rusted small fasteners to hammer them lightly with penetrating oil to knock them loose.
The little impact saved me some trouble a few weeks ago with a recessed frozen Phillips head screw i couldn't get a hand impact on. I put a bit in the tools and it blasted them right out

I wouldn't be without it, my little Makita is still going strong after 5 or 6 years, it it broke today i would have have another one ordered this afternoon.

I have a Bosch HTH181 half in impact gun which is about eight years old and is rated at 450 ft lbs torque.

Yesterday I took off my summer tires and the gun was at its limit taking off the lug nuts which had been torqued to 140 ft lbs. I don`t like to keep hammering on and if it does not start turning in five secs, out comes the breaker bar.I checked the torque on the lug nuts with a breaker bar and they were not seized on.

The age of the battery must have played a part and the fact that the temperature was below freezing did not help. But ,in general, I find that in real world conditions do not expect more than half the manufacturer rated torque from impact wrenches or drivers.

I do some work on medium duty trucks with lug nuts torqued to 500 ft lbs. The IR2135ti pneumatic gun is rated at 780 ftlbs and the cordless W7150 is also rated at 780 ftlbs. I would not use either of these guns for taking off the wheels.

On these points, tell me if I'm wrong, but I thought that a breaker bar could actually be the wrong tool compared to an impact, because the breaker bar's constant torque is more prone to shearing off the fastener.

Totally agree. I have a couple little bosch 12v drivers that do great for that sort of stuff. I think the drive setup on. The subject tool is ingenious and I wash all were that way. Much more useful.

Isn't your makita actually 3/8" square drive?

 

[Trav]

Yes it is but its the same tool just a different drive end. I have my dads 1/4 hex Makita also, it works fine.

These lug nuts were properly torqued on (I did them myself last spring) and they were not rusted on, so there was no danger of them shearing off. My Bosch was having some difficulty spinning them off, so out of curiosity I checked the torque on the lug nuts with a breaker bar and it felt very normal.

I have a Makita 18v impact driver with a female 1/4 in hex drive. Love it but I will not use it for automobile lug nuts that take 80 ft lbs. I don't think the 1/4 in drive will last with that kind of torque.

No way is it taking lug nuts off without endless hammering, its not made for that. Like you sayit wont last ling ding that sort of work.
Lugs and large bolts get the air impact raging from 1/2 to 1" depending on how much of a bugger and how big it is.

Paul - the Milwaukee M18 Fuel High Torque 1/2" impact can probably go head to head with almost any 1/2" air impact wrench with respect to removing difficult nuts and bolts. But its probably heavier and might not take the abuse an air impact wrench can take (drag across the floor by the air hose).

 

[Trav]

Oh yes the big 1/2 cordless will do lugs i was referring to the small 1/4 and 3/8 drive models.
