4pcs Diamond Hand Polishing Pads for Ceramic Tile Glass Grinding,Sanding Blocks 60#,100#,200#,400#

I use these to smooth out rough spots on my glaze-fired pottery and they work really well. They seem pretty durable too and have held up nicely so far. Happy with them!

These pads work great! I have used several "name brand" sponges/pads and there is very little difference in quality. These work exactly as they are designed to work and come at a fraction of the cost.

Used to hone carbide rotary hammer bits these pads extend the life each bit. The 60 grit is great to remove some of the hardened steel that holds the carbide bit to give better access to the carbide itself and the 100 grit plus is nice for the honing process. I've sharpened my bits multiple times doubling and tripling the life of each bit (so far) for about 6 minutes of sanding per bit. This saves money on new drills, but is also reduces waste and throwing drill bits away after dulling once. If these pads can hone carbide, 8.5 on the Mohs scale, it proves they are a diamond product which is a 10 on the same scale. I have no doubt they will sand any other material I may use them for. I have not noticed any erosion of the sanding surface yet, I've only used these on the drills which uses the edge of the pad. The pads suffer near the edges but that is expected when sanding hard and rough surface. In time I may try and trim the pad smaller to expose new diamond material if the edge ever wears out. The image shows three used bits. Two I have resharpened on the right (more than once) and a dull bit is on the left.

The sanding pads work pretty well. Not gonna do a lot to a porcelain tile, but enough to keep yourself from getting cut up. Easy to use and pretty cheap. Not sure they’ll last longer than one job, though.

These are super easy to use and they are quite effective. I strongly recommend wearing thick gloves or you risk "sanding" some of the skin off of your fingers and palms.

Fixed my f-up.

Covers the basics of sanding, works great for glass.

I got these to remove excess cement film off some landscaping rocks. Haven't used them yet but once received it was an obvious used return as the 100 block was already greyed out in the center with the abrasive plate worn. For $11 I'm fine with it but I did use the same 100 to try to remove hardened food off a 16 inch knife edge and it did a horrible job. Again it was $11 but these seems to be worse then a regular sanding block.

They work great!

These are excellent to remove hard stains or acid marks from tiles.
