Surge Impact "WRENCH"

[DFB]

So why don't they make one?


I have the first M12 Fuel 3/8" impact wrench, the 2454 and it was sweet improvement on the original brushed 2461 which I had first. The 2454 Fuel wasn't very much larger than the 2453 Fuel impact driver in size when they first came out yet over time the M12 driver got insanely smaller . And now the new M12 Surge is pretty much the same size

Sometime ago quite a long while back when the M18 SURGE first hit the market some here on TGJ claimed it not would work well as an impact wrench I assume taking face value of the advertised torque rating. Personally I had no way of knowing short of purchasing one to find out for myself.

So read this test article and was quite surprised to learn the new M12 Surge can easily outperform the latest M12 Fuel impact driver in break away power.

Just seems like it might be a great alternative or companion wrench to the popular M12 Stubby and natural replacement for the venerable 2454 which has pretty much been orphaned now, keeping a smaller streamlined body impact, the noise reduction of hydraulic and a possibly a slightly more competitive kit price

This is pure speculation, but I'm gonna say heat may big a big problem trying to use it as an impact wrench.

I mean, real hydraulic impacts do exist - but the fluid gets cycled out of the tool..

Interesting point...but what would possibly make the driver any different?

Would think that running down screws all day would easily create excessive tool heat also and maybe even more so than just some random ugga dugga's

I'm no expert by any means - but if I had to guess - I'd say that hammering on screws for a few seconds while they're moving - might be different than hammering on a bolt for 10/15 seconds a shot with the thing never budging.

I read the article (most of it) but my understanding of how pusle drivers work is they sustain a smaller force longer - rather than a bunch of faster harder hitting impacts.

I'd have to imagine a harder hit would be better for breaking things free - esp when they don't really wanna come off.

I mean while the surge MAY work doing that - I can only assume the thing may not live for 5 years if that's all it ever did, esp with bigger bolts. (Cause u know people are gonna always try it)

I'm just guessing. I can be completely wrong.

“Pulse guns” have been around a long time. They are used on assembly lines mostly, They make less noise, less reaction force, and are adjustable, by air pressure or a screw that controls the bleed off rate of the hydraulic fluid. I can’t vouch for their ability for zipping off seized bolts, but they are pretty strong when turned up to the max. Atlas copco and uryu are some of the big names.

There is a whole nother world of tools out there besides auto/construction...

I am thoroughly confused by the torque results of that test. When I was doing research into the M12 impact and Surge, the tests were showing something different. They were neck and neck in smaller fasteners but bigger fasteners the impact had an advantage.

I have the M18 surge and the normal M18 impact driver and the M18 impact wrench all in FUEL and the surge has nowhere near the power of the impacts. I'd say the surge maxes out at about 30 ft-lb which is what I believe Milwaukee rates it for. It's a killer screw gun but not a nut buster.

Yeah and iirc in tests the M12 Surge isn't as powerful as the M18 Surge (even though they both claim 450 in-lbs).

Yeah no way the surge is a replacement for the M12 Fuel 2454 3/8 impact. While I dont have the M12 surge, I have been a fan of the M18 forever. In my big impact lug test last year, I did include the M18 surge for shits and giggles. The 2454 passed the lug bolt test, the M18 surge sounded like it was going to explode and I thought I broke it, it had zero chance.

On small fasteners the surge is great, but I would never grab it for anything but wood screws, sheet metal, or maybe about 5-8mm bolts/nuts.

I think something is wrong with that test.

Their results for the M18 Surge and M18 Fuel impact.

M18 Surge- 912 in-lbs of fastening torque and 2880 in-lbs of nut busting torque.
M18 Fuel impact driver- 2656 in-lbs of fastening torque and 3600 in-lbs of nut busting torque.
