7/8" Radial Discs - Fine Blue - 400 Grit

1/16" Arbor 

12/Box

Use with mandrels: 5425 (3/32" x 1/16")

No matter what the material being worked, radial disks are the "absolute best" for finishing & polishing hard-to-access areas without removing detail or causing flat spots.

The sharp, clean, specially treated ceramic abrasive grain imbedded throughout their thin flexible bristles enable them to work faster and last longer than rubber wheels, brushes, buffs and conventional sanders.  

These high quality disks generate minimal dust and heat and eliminate the need for polishing compound.

Recommended operating speeds for most applications is 3,000-18,000 RPM (5,000 RPM for woodworking).  Lower speeds allow a softer touch, greater flexibility and more subtle results.  Higher speeds provide more aggressive material removal.  Using the tips of the bristles with light pressure maximizes disc life.

Jewelry -  Ideal for finishing, smoothing and high-lustre polishing of all precious, semi-precious and non-precious metals, acrylics and ceramics.  Pumice discs will not scratch stones.

Owen F. ★★★★★

These blue 400-grit discs cut through burrs on stainless steel surprisingly cleanly without loading up. I've been using them with a 1/16" arbor mandrel and the fit is perfect.

Henry R. ★★★★★

These blue 400 grit discs chew through steel burrs fast, and the 1/16" arbor stays locked in the mandrel without any wobble. A full dozen in the box means I didn't have to reorder mid-project, which is always a win.

Emma ★★★★★

The 1/16" arbor fit my mandrel perfectly, no wobble at all. These blue 400 grit discs are doing exactly what I needed for smoothing out small metal edges without scratching the surface.
