24 grit moves a lot of wood!

Haven’t had one of these on a grinder in over 20 yrs. Excellent for field trimming timber framing and exterior deck posts. Don’t live with out it from now on

My first order

I was pleasantly surprised with my first order from Empire Abrasives! Within hours of submitting my order, I received an email notifying me that my order had shipped. The product is very durable and about half the price compared to buying local. I’m very satisfied and will use EA for all my abrasive needs in the future.
