Green Stone burs are impregnated with silicon carbide grit for fast contouring and finishing. Polishing Burs are excellent for surface characterization and adjusting details. These long lasting, fast cutting and concentric bur are perfect for polish on glass and ceramic. Also good for grinding metals. Can be used in place of diamond burs. Notice: Green Stone burs must be run at a lower speed – less than 150,000 RPM. *Each bur is sold individually.

Bur Extractor Tool is designed to help you remove the smallest of burs from your Vortex F5 Carver. We found very small steel needle nose pliers works best. These heat treated steel needle nose pliers is the perfect tool for removing the small burs like the FG-33½ or FG-¼. These needle nose pliers feature a nonslip comfort grip and a drop forged construction for added durability.
Directions:
1) Twist Vortex F5 cap to the open position.
2) Grip “shaft” of bur with Extractor Tool.
3) Carefully nudge the bur from the spindle.
4) Replace bur by wiping the shaft clean.
5) Seat bur completely into the spindle.
6) Twist Vortex F5 cap to the close position.
Ceramic Bearings are ideal for the Vortex F5. They are superior to common steel bearings in many ways. Ceramic is the ideal material for obtaining higher RPM (faster speed).
Ceramic balls need less lubricant and have a greater hardness than steel balls. This contributes to increased bearing life. Thermal properties of ceramic balls are more superior than steel resulting in less heat generation at higher speeds.
Ceramic bearing assemblies use ceramic balls but they are constructed with steel inner and outer rings. Ceramic balls weigh up to 40% less than steel balls. This reduces centrifugal loading so ceramic bearings can operate up to 50% faster. Also, the outer race groove exerts less force against the ball as the bearing spins, reducing the friction and rolling resistance. The final results, ceramic balls allows the bearing to spin faster and uses less energy to maintain rotational speed.
By not having to insert burs by bear down on a hard surface like other carving tools, radial bearings can be utilized instead of angular bearings. Radial bearings are better suited for carving on their sides. Angular bearings which are primarily used in a vertical position and drilling.
Permanently Lubed for Life Turbine Bearings
Within the nosecone of the Vortex F5, there is a turbine bearing assembly. The bearings are permanently lubed and never need oiling. Warning: using an in-line mist fog oiler or placing drops of oil or cleaner into the hose may cause damage to the carver and void the warranty.
