Up-Spiral Plastic - 3.175x12

Engineered for precision and versatility, our single flute up-spiral bits are designed with optimized geometry to deliver superior edge quality in plastics, wood, and other general-purpose materials. The wide-open flutes allow for mass chip evacuation, while the high helix angle and razor-sharp cutting edge reduce heat buildup and ensure a clean, smooth finish—far outperforming standard up-spiral geometries.

Crafted from 5A+ German carbide and precision ground, each bit is mirror-polished for enhanced durability and cutting performance. Ideal for high-speed routing where surface finish matters.
