BHA Green Zirconia with Grind Aid Quick Change Sanding Discs Type R Male Roll On, 2" (36 Grit) - 25 Pack

Last 3 times longer than the other ones

The title sentence says it all.

After using the discs. The grit doesn't chip off like some heavy grit discs. It chews up hardened steel fairly well.

Cost more than the competition but disc last longer. Overall good quality.

Using these to grind down spot welds. They don't last very long.

I am Pro auto technician 40 years in the buisseness would recommend them to the do it yourselfer or a professional.

I bought these for my home shop. Similar to discs I've used at my work, but not quite the same quality.

I have tried plenty of others these are the best bang for the buck.
