SUNBURST 7/8" Knife-Edge - Pink (Fine) 600 Grit (Pumice) 12/Bx

No matter what the material being worked, SUNBURST wheels are the "absolute best" for finishing & polishing.
The sharp, clean, specially treated ceramic abrasive grain imbedded throughout enables them to work faster and last longer than all other rubberized abrasive wheels.  
SUNBURST wheels generate minimal dust and heat and eliminate the need for polishing compound.  Ideal for finishing, smoothing and high-luster polishing of all precious, semi-precious and non-precious metals, acrylics and ceramics.  Pumice wheels will not scratch stones.
Recommended operating speeds for most applications is 3,000-18,000 RPM.  Lower speeds allow a softer touch, greater flexibility and more subtle results.  Higher speeds provide more aggressive material removal.
