The sanding block I currently use is whatever scrap wood I can find — this works well for the most part, but the possibility of something better out there piques my interest. Looking at all the various options, I’m thinking a basic model would be best for me, rather than a more ergonomic one, and I want something that takes a quarter to a third of a sheet. 3M’s 9248NA Sanding Block fits these requirements, so I’m going to give it a shot.
It’s built for heavy to light sanding and is good for paint, wood, and metal, so it should handle any project I can throw at it. It uses a quarter sheet of paper; the old block of wood usually uses more, since I have to wrap the paper around the block. This sander measures 2-3/4″ by 1-3/4″ by 5-1/4″ and weighs just a quarter of a pound, and it’ll work with 3M adhesive-backed paper or regular paper.
3M’s Sanding Block Kit, which includes the block and five assorted sheets of sandpaper, sells for about $5 — cheap enough to always keep one or two on hand.
