18 PCS 3 x 18 Inch Premium Silicon Carbide Sanding Belts Assortment- 3 Pcs Each of 80,120, 240, 400, 800,1000 Grits Knife Sharpening Sander Belt Kits for Belt Sander (3x18 inch)

We were happy to find this group because we have an older sander and it was hard to find the longer belts where we live. There's a nice varied selection and I've been using the 1000 grit to sharpen the kitchen knives and they are coming out great. My wife is always on some project so they get used a lot. We haven't had any problems and I think we've been using them for a month or two.

Durable sansing belts

The supper fine grit is okay, but the coarser belts are crap.

I use this sending Bells for wood and metal sanding in a dozen great job on both doesn't clog as much as regular sanding belts.

They work great for grinding steel. No problems.

Price and durable

These work, but like most cheap products, they wear out faster than you can imagine. A set of four will MAYBE allow you to polish up a single set of steak knives. These are probably not worth the money, even though they are cheap.

All belts have grit and direction markings. I have not used them so I don't know durability and performance . The 1000 grit is visibly rough and gives a finish closer to 400. I wonder about the other grits.
