I saw a video of a guy cutting steel like it was butter  hogging steel off a one inch bar like it was nothing .  Mere seconds  and he ws removing serious amounts of metal.

So I got some

I got 7" disks and 4.5" disks  They are expensive but last and last and last and  oh  boy do they work.  For example I'm sharpening my  Ferris 48"  mower blades in mere seconds.

and  the 87" ones below

There is a trick to using 'em.  Light pressure.  Don't lean on them like you will with a flap-disk or a grinder disk.

 

 

Thanks for the links, Cliff

WOW, impressive but also WOW on the price.

The is total sticker shock.

I retired from welding years ago and won't need these for my woodworking. Guess I'll pass on these. $$$$  Thanks anyway.

They are so worth it.  and they last and last.

I can't tell you how many times I've started  descaling with a flap disk only  to find that they NEVER - - - EVER perform as they should  the exhausted flap material does not abrade away exposing new grit and I end up throwing them  away  getting almost no life from them.

One of those Pferd disks will still be humming along long  after you have gone through the last of your ten pak of flap discs.

Pferd makes good files, too.
