The card works well. It paid for itself twice over the same day I purchased it. The trick is to wait until there is a 25% coupon available, that and your card plus if it's on sale makes for a huge bargain. I bought HF's huge jackhammer. The best is a Hilti at $2999 or a Bosch at a bit less. HF's 70 lb hammer is $460 normally but with it on sale and a 25% coupon, it was only $2xx out the door. It hammers like a mule and much better than others I have rented. Friends have borrowed it and years later, it still works great. It's really heavy but I guess it has to be. Plastic trigger handle might be hard to find if you broke it. https://www.harborfreight.com/15-amp-70-lb-pro-breaker-hammer-63436.html

The 20v Earthquake has been on sale recently for $219. I'm interested In the jack hammer, but I'm pretty sure that you can't use the discount coupons on sale items.
The fine print at the bottom of the coupon now lists almost every expensive Item they sell. Either by brand name or general description, such as welders, jacks, etc. Along with "cannot be used with any other discount"
They let me use the coupon on the jack hammer even though it was on sale. I was bummed when I arrived at the store as I had forgotten the discount book. The checker took me aside and showed me how to get the coupon on my phone. Could not have been more helpful. I'm not a weakling but we had to trade off on the jack hammer after about 5 minutes. 70 lbs is a lot to keep moving to another spot.

I bought a tool box couple of months ago. They wouldn't take the 20% coupon I had. They said it didn't cover cabinets or tool boxes. But told me if I found a coupon somewhere, they would refund the difference.
Went home and Googled Harbor Freight Coupons, with the tool boxes number.Found several with big did counts. Took it back, and got $32.00 back.

I was able to get a lot of time on jackhammers while on our FEMA US&R team. We had everything from hydraulic ones (confined space) to the small hand held rotary hammers. The larger the tool, the more effective it was in breaching concrete, but the downside, as you mentioned, was the burn out factor. You don't know fun until you are lying on your back in a crawl space with the hammer bit resting on your crossed boots while you bang away horizontally and the exhaust is kicking up dust. We found the lighter duty JH to be useless for heavy concrete, but if you are using it with a spade bit for hard pack dirt, the lighter weights are the way to go.
Exactly! The small hammers are useless for concrete, just give you a headache listening to them. When I was putting in my almost 1/4 mile driveway, the old blasting guy next door gave me a lesson on blasting and a license to go with it. Then sold me quite a bit of dynamite and blasting caps. $3 a stick or cap. Lots of fun. An inch and a half of dynamite blows up about a 4 foot size rock and a half stick will take care of an eight foot boulder.

The 20V removed my tires today . Well worth the 280$ IMHO.
I just bought and returned the Earthquake 62891. 1/2" composite Xtreme torque air impact from Hong Kong freight
Rated at 1190 ft lbs @ 90 psi.Lots of positive reviews.
Wouldn't budge a lug nut with 120 psi.
So waiting till tomorrow for my torque amplifier. $50.00
Good for breaking bolts loose, but not dependable for re-torquing them. les schwab 2 miles away will re- torque them for us. We bought our tires there.
Rotating tires side to side, while servicing the slide pins.

HF does sell a 3/4" impact rated at 1700 ft lbs for $260 before any discount. That should twist off any lug nut.
Chris, how big diameter and long was your air hose? Big impacts need large diameter hoses and good to limit to 25 feet or there is a big friction loss.

Thanks for the info Pierce
Just didn't want to spend that kind of dough, for one time use. I had the Torque amplifier coming already, I know they work.
I have a 1/2" impact already that works for everything else.
I did do a bunch of research, this one had lots of positive reviews, and actually the one you posted, was way low on reviews.
Yup, high flow fittings, 25' hose, and compressor kicked up to 120 PSI. Didn't move one of them 1/16th"

I grease all of my nuts and torque them to , one wife on 4ft pipe.
Mine all came off with the 20V .
I have the new A/C powered electric impact that advertises about 1200# of energy, I have yet to be stopped by any lack of power. At about $90 its hard to beat.
I also have the low end HF 3/4 air impact. I have a 1/2" dedicated air hose for it, It also has never been lacking of power.
Bought the HF 3/4" impact wrench about four years ago to help change the timing belt on our Saturn Vue. Used it once and it sat in its box in the garage until last week. Never got used again so am giving it to the man who is repairing our lawn tractor, along with (2) 6" 3/4 extensions and (1) 3/4 to 1/2 drive reducer.
In a HF email ad I see the 1/2" corded impact, 1050# of torgue, on sale now for $69.99. Best price I've seen.
I ordered another at this price for a Christmas gift for my son.
