The Onsrud 56-063 is a high-performance spiral O flute upcut bit crafted from solid carbide for long-lasting durability and superior finish quality. With a 1/16" cutting diameter, this single-flute design enhances chip evacuation and reduces heat during cutting — making it perfect for machining acrylics, soft plastics, and non-ferrous metals like aluminum.

Whether you're operating a high-speed CNC router or need a reliable bit for precision engraving, the 56-063 delivers clean edges and reduced tool load. Its 1/4" shank ensures compatibility with standard collet systems, while the upcut geometry lifts chips away from the cut zone for improved tool life and material finish.
