Haddy like this bad boy, Clark?  Thanks for the tip.

LOL..yeah..it's a stud-breaker on max..be careful. If you really want some power out of it, go up a size on the line with the fittings...and crank the compressor up to 150psi. It's ..."scary".....lol. That's what it took to get my secondary nut off.

Try the lithium ion Milwaukee Fuel
Série....

These air-guns are beautiful........but I don't like them. I sah to much damage with these things in unskilled hands.
Something stuck............o just put air on it. Wenn its broken they come to me to fix it. There are people who even use air vor every bolt and nut.
They are nutz. With decent tools and a good Nm tool you can fix everything. But that is just my opinion.

I hear ya. Wrenching on things successfully takes a certain feel for what you are doing. I have a buddy who got an electric impact and he doesn't seem to even think about what size bolt he's working on, he just hammers away on any of them just the same. I cringe.

glenlivet, have you tried to find a Cdn supplier for these products? Looks interesting, lifetime wtty on drill bits   

I'm shopping for 1/2 impact right with enough punch & small enough to get into the driven clutch area. Snap On has a deal on one right, nearly 1200ftlbs break away torque......still big money

There is a couple of other nuts when doing a engine tear down that are tight like the driven. It's a chore to hold some these things, so the big impact would be nice.

I use a lot of cordless tools, most have limited power so as to not hurt anything. Some even have an adjustable clutch which is really nice when working with plastic panels or the multitude 6mm holding crankcases together.

Got it on eBay for 85 USD on the advice of NMKawierider

It's handy for me because I can have things sent to a shipping receiver's address in Sumas Wa. and just hop across the border at Abbotsford and claim it for 3 dollars handling. Most times if I have under $200 to declare they just wave me through at the CDN side.

Glen, I bought the same one three months ago because of a two thumbs up from NMK....great tool and very light compared to most powerful impacts !! Use it everyday in my shop. (quick shipping also)
