Great for Surface Prep

I love these disks for cleaning mill scale off of cold rolled steel. They remove the scale without removing steel. The clean surface is easy to prep for paint. I've used similar disks from big box stores and they all disappoint. These last three as long and are a third the price.

Awesome for preparing steel for paint.

I use a lot of painted and rusty steel on projects. This is the most effective and longest lasting disk to prepare old steel to paint. Better than flap disks!

They work

The Black Hawk blue disc worked very well at cutting old paint off of my '55 Chevrolet. This is tough paint.

These work wonders

This strip discs are amazing! It took no time at all to cut right down through the rust, paint layers, and down to the bare metal.
