4.5" Ceramic Discs

I bought these for use mainly for blacksmithing projects and didn't like the cheap stuff they sell in stores that don't last well.I got them quick and tried one out using a b&d angle grinder and then my cordless dewalt, let me tell you these thing will munch metal like a pro, I can grind a fresh knife to shape in good time and no longer go through 3 or 4 of those cheap ones, matter of fact one will do 2 or 3 regular sized knives.When you use these on metal they WILL throw a LOT of sparks, please be careful when using them.Will they work for shaping wood? ABSOLUTELY! I'd say they'd work well even on petrified wood, just be careful and make sure that either your wood or your tool is clamped very securely and be aware these will remove wood VERY quickly.I will certainly be buying more.

I ordered these as a possible replacement for my 3M cubitron disc which I use to bevel pipe. As a pipefitter that bevels pipe alot day to day I whole heartly will say these out performed the 3M brand by far for a 5th of the cost. Will now be using these along with the DeWalt semi rigid backing pad from here on out. GREAT job BHA you knocked this one out of the park.

mine were warped in a way they were un usable

These discs are far superior to the cheap ones. The amount of material they can remove in a fraction of the time of others I've used is unreal. Will definitely buy again.

Exceeds expectations !

Supposed to be ceramic, which they might be but they wear out very fast compared to the harbor freight ceramic discs.

The finish is better than other compositions I’m familiar with. Ceramic apparently fractures in such a way that improves performance as it wears and it lasts way longer than other popular sandpaper’s. This belongs “in a perfect world”

These are NOT ceramic! Bad quality. Wear out fast. POS!
