Belin.Y 13000 series - 1 Edge Upcut Spiral O-Flute - Solid Carbide
Available from Hartlauer Bits
USAGE: Soft & Hard Plastics
These tools are manufactured by Belin in France. They are very similar to the Onsrud 63-700 series. One key difference is that the tools are polished on the outside as well as inside the flute. These tools leave an exceptional finish in hard plastic, and some success in wood despite their aggressive chip evacuation.
