The Onsrud 56-618 is a 3/16” diameter upcut spiral O-flute bit tailored
specifically for plastic machining. Manufactured in the USA, this solid carbide
router bit delivers clean cuts, minimal chip weld, and extended tool life when
used with acrylics, polycarbonates, ABS, HDPE, and similar plastics. The
O-flute geometry promotes superior chip evacuation, reducing heat build-up and
improving edge quality. Whether you're routing signage, enclosures, or
high-speed production parts, this bit provides consistent, smooth results.
