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.
