I've seen the 7.5A Mastercraft Impact Wrench down to $69-$79 but never this low before. It must be because they just introduced their Maximum 8A Impact Wrench on the shelves not too long ago (on sale right now for $79) which I picked up.

Will be exchanging the 8A Maximum impact wrench for the 7.5A version. For just swapping tires, I really don't need anything greater than 7.5A and savings of $30 between the two can be had.

This is a perfect medium use tool for many automotive and other fastening jobs.

NOTE - this deal doesn't commence until Friday, May 1st.

How is this for taking tires off and most novice jobs around the car, etc...?

Keep the 8amp version, Its much more powerful (350 ftlb+)

You can't judge the impact power looking at amps alone.

The impact power is generated by a hammer assembly, the 8amp has dual hammers while the 7.5 amp version only has a single hammer so its like 230 ftlb

It would be overkill for those jobs. I have the 3.5 Amp version-- I use it to change tires on all 5 vehicles including the SUV's. Works great for general car repairs. I also have an air tool which is a hassle to set up compared to the electric tool ...so I rarely use the air tool.

At this price you can't go wrong for a 7A tool.

What would be a decent socket set for this wrench? Not looking for something too big or expensive....

Mine lasted just over 3 years. Stopped working right after the warranty expired.

Picked up the 8A, it feels much stronger when loosening lugs.

That's good to know you have tested both the 7.5A and 8A and can tell that much of a difference. Will be keeping my 8A

i believe for 20 bucks more, you guys can wait for the MAXIMUM Impact wrench for 69.99. you have to wait for it to go on sale though.

I also have the 3.5A and it has no problems changing the tires on my SUV, my dad's truck and two other cars. Anyone who can't take their lugs off a typical vehicle with the 3.5A must be grossly over-torquing or experiencing excessive rust from salt like i've never seen before.

I sometimes need to use the help from the ol' breaker bar (10$ from CT), but yes the 3.5A works for me too.

Bought one yesterday. Now it's time to buy a socket for tire swapping. CT auto desk lady was not sure about the size of the socket to buy

Any insight and sale for a socket?

The sockets that you'll need to purchase are ones with a 1/2" square receptacle. It says so right on the box and or online description. If you are asking what kind of 3/4", 15/16", 20 mm, 22 mm, etc. hexagonal socket, then you should look that up on the internet or in your vehicle's owner manual for that info. Asking a CT auto desk lady for that info is really unfair and I wouldn't expect anyone to know that info offhand.

Depends on the car. Make and model?

I love this thing when it works. It will easily take off lug nuts that are not overtorqued and I've also used it on many rusted suspension nuts. Just make sure to keep your receipt. I've replaced 3 under warranty.

Thank you for the info. I thought it should be straight forward when you have all data; i.e. car make/model (in this case '14 Camry or '10 Mazda 3) and impact driver at hand. I did not have time to go through with the sales lady or to check the isle for further info. Non fo my socket set are 1/2" nor are impact and IIRC non did fit for the job. User forums were saying 13/16" or 21mm may fit. Also need to know tork settings and find something fit I guess.

Toyota full size vehicles are 21mm. Don't use the 13/16, it's not exactly right and 21mm isn't hard to find.

Torque settings are in the manual. Camry should be 78 iirc.
