These stones were very useful in grinding the damaged head off a screw so equipment could be disassembled for repair without damage to the equipment itself. The remaining stump of the screw was then easily removed with pliers.

Seem to be well made for the money.

All of the myriad sanding pieces, whether white blue or whatever were exactly the same with absolutely no grit on them at all. Much better to invest in one or two well made grinding stones from a good carving shop and they will last for a long time. These stones did not sand even the softest of material because there is apparently no grit on them at all.

Price to high for small abrasive working bits.

I bought these to use in my dremel for sanding Petoskey stones because they’re a soft rock. Whatever is coated on them is horrible so they don’t sand whatsoever. My daughter even tried them when she does acrylic nails and said they don’t even work for that. Huge disappointment

Very nice long life! Recommended!

they work good

Great value
