SUNBURST 3mm Pins - Blue (Fine) 400 Grit (Aluminum Oxide) 100/Bx

No matter what the material being worked, SUNBURST polishing pins 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 rods enable them to work faster and last longer than conventional silicone and polyurethane pins.  
SUNBURST polishing pins generate minimal dust and heat and eliminate the need for polishing compound on all precious, semi-precious and non-precious metals.
Recommended operating speeds for most applications is 3,000-18,000 RPM.  Lower speeds allow a softer touch, greater flexibility and more subtle results. Using the tips of the pin with light pressure maximizes tool life.
