Rusty, I'm gonna throw this out to you...
If your not familiar with air tools, the set your looking at is basically a light duty "beginners" set. The tools, while Craftsman in name, aren't the best . The impact, at 300 ft lbs, will remove some stuff, but it won't budge a properly torqued 3/4 or one ton truck wheel lug nut. And, its a single speed which means if your not careful you'll strip a bolt/nut very easily. The second you hit the trigger it hits 300 ft lbs. A gun with a variable speed trigger is the way to go. You can hit the trigger and apply the torque slowly...very easy to manage.
I have several, and a 300 lb won't budge the lugs on my E-450 based motor home wheels. Takes at least a gun with 450 ft lbs, and when I travel I carry one rated at 600 ft lbs.
The ratchet is only 45 ft lbs...better ones go up to 60 ft lbs .
If you already have a compressor and hose, and only need a ratchet, go for a better one, and add to your tools as needed.
There is a reason why the impact your looking at comes in an 80 buck kit, while a good quality gun with 450-600 ft lbs can cost hundreds of dollars.
You do get what you pay for. I've got a number of air tools that I paid dearly for over 30 years ago, but I still have em and they still work like new.
If your only going to do some light work, then that kit is a good buy, but for heavy duty with a lot of use, not worth it...you'll be looking for better tools shortly.
Those two tools are going to be the most expensive. Tools like air hammers/chisels, die grinders and cut off tools are relatively inexpensive.
