The other day I was searching for sanding block designs and instead I found something interesting: carbide hand sanding blocks. In particular, I discovered these Tru-Sander carbide sanding blocks from Dura-Grit.
When using a traditional sanding block, you’ll go through sheets and sheets of sandpaper as they wear down with use. But with these Dura-Grit Tr-Sander carbide sanding blocks, the 5-1/2″ x 2″ tungsten carbide-coated plate won’t wear down like “ordinary” sandpaper, and will always be the same grit as when you bought it, at least according to Dura-Grit.
(Well, maybe not always, but it should take a lot of use and a very long time before there’s any noticeable wear or reduced performance. Tungsten carbide is a very hard and wear-resistant material.)
The Tru-Sander can be used on wood, MDF, engineered or laminate flooring, fiberglass, rigid foam, ABS, PVC, rubber, gourds???, and many more materials, and they specifically recommend against using it on metal.
The wooden handle can be used comfortably in either hand. One edge of the sanding block is perpendicular to the cutting face, so you can use it to square up the edges of boards, or keep them square as you sand them.
Dura-Grit even claims the Tru-Sander has dust collection built in. There are concave depressions running behind the perforated tungsten carbide coated plate, for trapping dust. You can just tap the block on it’s side to clear the dust away, and the plate can be cleaned with a steel brush if necessary.
The Tru-Sander carbide sanding block is available in 60, 80, 120, and 150 grit. You’ll pay $38 plus $7 for the cheapest shipping option.
It doesn’t look like you can swap out the plate, so you’ll have to buy a separate block for each grit size.
Price: $38 plus shipping

DuraGrit also makes other tungsten carbide coated sanding products, like 5″ carbide sanding discs and 1/4″ carbide round files, as well as high-speed rotary carbide burrs, all of which are interesting products in their own right.
What I don’t get is that the Tru-Sander used to be carried by Amazon, Woodcraft, and a bunch of other distributors for about $22. Now the only place I can find them for sale is the Dura-Grit website for almost twice the price. I’m not sure what happened, maybe they didn’t sell well enough to be carried by these other distributors?
Has anyone used a Tru-Sander or another tungsten carbide coated sanding block? Do the claims that they’ll last 100x longer than sandpaper actually hold up? And if they do, why is this product not more widely available?
