They have good quality abrasives and glue

They have good quality abrasives and glue. I've had some PSA discs that peel off after sitting for a while, but they seem to be holding up pretty well. And I've really dabbled in profiling a 1/4 inch piece of steel and they have held up to use (abuse).

Pros
  • Slim design
Cons
  • Not all fit

Outstanding performance!

I've been experimenting with grinding H-13 steel on a 90 degree straight grinder (25,000 rpm). Its performance is amazing. As the brake pad wears, it will still continue to cut and show minimal wear. As heat accumulated, the adhesive backing showed no signs of delamination. Even in high heat, it doesn't leave any sticky residue on the holder in my coffee grinder after completion. The glue is phenomenal. Perfect for the finish I was looking for.

Pros
  • An absolute legend
Cons
  • There are disadvantages

Dangerously poor adhesive quality

Bought specifically for the Norton brand. They have had good experiences with their grinding products in the past. Heavy grit holds up well, but adhesion to the grinding wheel is VERY poor. In fact, one of the discs broke off the platter at high speed and flew into my (prescription) glasses, leaving deep scratches on the lens that would cost $140 to replace. So if you decide to buy it, I recommend cleaning the plate. Use alcohol or other solvent and spray adhesive to attach the wheel to the…

Pros
  • Satisfied so far
Cons
  • Hard to say
