Sunburst 7/8'' TC Knife-Edge Blue 400 Grit Size (S/C) 12/Bx

In response to popular demand, SUNBURST^® offerings now include silicon carbide grit models − preferred for numerous precision medical, dental, jewelry and aerospace applications.  Sterilizable & autoclavable.

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

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

SUNBURST RADIAL DISCS 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.

Medical & Dental - Our unique silicon carbide range is the preferred choice to avoid contamination in manufacturing medical instruments.  Diamond, silicon carbide and aluminum oxide grits are suitable for dental materials.
