PORTER-CABLE 7800 Drywall Sander Review

A drywall sander may not be the most common of power tools but if you are into DIY, you may sometimes need a drywall sander. It will save you a lot of time but unfortunately, a good drywall sander is expensive.

One of the best drywall sanders is the Porter-Cable 7800, it is expensive but you get what you pay for. It is relatively lightweight but powerful. Variable speed, 5 settings, makes it possible to choose between control (using low speed) and fast stock removal (using high speed).

One of the main advantages of the Porter-Cable 7800 is its excellent dust collection. You are supposed to use a shop vac. The hose is 1 1/4″ so you may need an adapter if you have a 2 1/2″ shop-vac. Of course, there will be a little bit of dust which is not collected but clearly less than with most other sanders.

Additionally, it has hook-and-loop straps for easy mounting and handling as well as a 13-foot vacuum hose making it very mobile. It uses standard 8-7/8 inch hook and loop abrasive discs.

The Porter-Cable 7800 Drywall Sander comes with a one year limited warranty.

Porter-Cable 7800 Drywall Sander Customer Reviews
With an average customer rating of 4.4 out of 5, it is quite clear that the customers are happy with their Porter-Cable 7800 Drywall Sander. Most of the customers said that it was easy to use, efficient and had a very good dust collection system.

Although the Porter-Cable 7800 is not heavy (8.5 pounds), some of the users said that after a while their arms got tired, especially when doing ceilings. Since the Porter-Cable uses round discs it cannot reach all the way into corners but nobody was really concerned about this. Probably because it is only a very small part of the corner you have to take care of manually.

Here are some typical customer comments:

“life saver for ceiling work! product worked as described and has very little dust when using. I used my shop vac and installed the high efficiency bags. this worked fine. the tool works great and has plenty of power. ”

“Saves a ton of time & reduces dust. The quality of the sander & length is much better than other (similar) sanders.”

“This is a great tool. I have been using it in conjunction with the Porter Cable Power Tool actuated Wet/Dry vacuum and after over an hour of sanding it left my job virtually dust free. The variable speed on the head is a plus and changing the sandpaper is a breeze. The vacuum is a little noisy, as one would expect from any powerful shop vacuum, and the sander does get heavy after a while.”

“I have had this unit for over three years now and it has saved me countless hours of sanding mud and hiring a drywall crew. I build custom homes and do remodel work for a living,so any tool that saves me time and makes me money is worth it. I would highly recommend this sander for anyone who is in the trades, you wont be sorry!”
