Review on 🛠️ PORTER-CABLE 5-Inch Hook and Loop Pad for 7334, 7335, & 97355 Sanders - 5-Hole (15000) - Ultimate Sanding Upgrade! by Robert Dabney

This review is of a replacement pad for your existing grinder. My Porter Cable Random orbital sander failed almost simultaneously. They looked perfect, but when I turned on the sander, they broke into pieces of foam, leaving a metal disk on the sander and velcro on the sandpaper. I didn't even have to touch the pad to work. It happened with pads 15 or 20 years ago, but it happened at the same time. Both the Velcro and PSA padding failed along with the plastic dust cover and foam padding in the metal box that contained the grinder and accessories. I suspected environmental issues but can't figure out what's wrong. would. There were no chemical fumes (other than outgassing from various objects in a sealed metal box). The temperature range is 50 to 100 degrees Fahrenheit. The service life of the sanding pad is therefore 15 to 20 years. not bad considering the hooks still worked. Replacing the lining is very easy. While holding the grinder shaft in place with an open-end wrench, unscrew the pad (or metal plate) by hand. Screw in the new gasket tightly. It will pull itself up. If you want to know the direction of the thread, look at the bolt on the new cover. Do not use the sander without the sandpaper attached to the pad, or you may need to replace the pad due to missing hooks on the pad. They wear out very quickly in direct contact with surfaces other than air or grinding. UPDATE I thought I should follow my own rule of providing the information I really want in a review, especially when the product description is very thin. I think this one fits. First, Porter Cable manufactures 5" and 6" models of grinders and polishers. The large Heavy Duty models (marked HD) require two hands and are based on their rectangular grinder. They are powerful and heavier than smaller models that can be held in one hand. 7335 is an example of the HD variant. Model 333 is an example of a small model. A counterweight is located in the free circulation area of each mill, which is located between the motor and the disc. It is important to purchase a replacement pad that matches your grinder's counterweight. So if you had a 5 inch pad, buy a new 5 inch pad. If you decide to change the size of the pads, you will need to buy a different counterweight and dust cover for the new pad size. ) and pressure-sensitive adhesive (PSA). HL sanding paper is now significantly cheaper and more convenient, because frequent changing of the sanding pad when sanding wood works well despite the different grit and HL sanding sheets can be reused. On the other hand, in my experience, PSA grinding wheels are disposable. Also, the abrasive disc can stick too well, resulting in some paper remaining on the pad after the disc is removed. It must be erased before installing a new drive. Another difference from PSA is that the pads are smooth (no holes for dust) so dust removal is a problem and the paper and pad can overheat due to dust buildup. Incidentally, this causes the paper to stick too well, so remember to wipe off excess dust often. I use a PSA pad and paper to sand with a 40 grit 7335 HD sander. It easily copes with difficult tasks (e.g. on the hull of a boat or on a laced patch on an oak floor). I also have an HL pad and use it for all other sanding work. Changing pads is quick and easy. HL holds grinding wheels well down to about 60 grit, while PSA works well with 40 grit. In fact, I've found that HL isn't available in big box stores below 60 grit, while PSA up to 40 is available. The easiest way to do this is without grinding with a disc. A few seconds of contact is enough for all the hooks to disappear. Prolonged use (removal of many thousands of grinding wheels) leads to the same result. Things wear out. Just buy a new gasket.
