Customer Reviews

Outstanding service for 30 years
I bought my Porter Cable 330 Block Sander in 1970 and it has performed flawlessly for 30 years. I am only now replacing the four small rubber posts that insulate the upper housing from the vibration of the pad. This sander uses only 1/4 of a sheet of sandpaper, but is, nevertheless, a high quality, durable machine that can be operated continuously without failure. It is an orbital sander, not a random orbital or vibrating sander, and uses three separate sealed roller bearings - two on the armature and one on the pad. It is a tough machine, built to handle sanding chores in areas where larger sanders either won't fit or are too cumbersome and akward to use, such as sanding on the sides and bottoms of drawers.

Quality Piece, a probable heirloom!
I purchased one of these a couple of years ago to finish sand the maple cabinets I was making for my wife's kitchen. They are pretty much one-of-a-kind in that the raised panels are made from Eastern Curly Maple and the stiles and rails are Birdseye Maple. The point is, of course, this is a super hard wood, that is difficult to work with, and takes a while to sand. This sander worked flawlessly, efficiently, and more importantly, comfortably through twenty-five of these doors. I think that is what really sets this little sander apart from all in its class. It is quiet, and its ergonomics make it a pleasure to use. It does use slightly more than one-quarter sheet of sandpaper, though, to cover its base and fit in the clamps. I readily recommend this sander for finish applications.

The absolute best 1/4 sheet sander
I have been doing cabinetry and custom woodowrking for many years and have owned and used many, many pad sanders. For a 1/4 sheet model, this one is the absolute best. I bought my first one 27 years ago and it was still going strong when it was stolen about 4 years ago. Fortunately I bought a second one about 10 yrs ago which is getting plenty of extra use now.

I've melted down a few Makita's and Black & Deckers (they made my hand go numb after 5 minutes use anyway) but this model just keeps on going. Not only smooth, it's extremely durable and easy to do maintenance on (and it lasts the years so you get the chance to).

About that key: I switched my old 330 out years ago to take adhesive backed abrasives and my newer one already has that capability. I never used that key anyway... a screwdriver did a fine job if I did want to used standard sandpaper. That is such a minor thing compared to the superior performance, life, and smoothness you get out of this sander.

After two sanders owned and a handful other 330's used... this is the champ. If you want a bigger sander, blow some pennies on a Porter-Cable 505... it'll last longer than you will!
