The Onsrud 60-905 is a high-performance 1/2" diameter compression spiral router bit engineered to deliver exceptional edge quality in a wide range of wood materials. Featuring a dual-flute solid carbide build and a specialized compression geometry, this bit pulls fibers toward the center of the cut — preventing tear-out on both the top and bottom surfaces. This makes it a go-to tool for panel processing, nested-based manufacturing, and applications involving laminated or veneered materials.

Onsrud’s compression spiral design is specifically suited for CNC routers running at high speeds with feed rates that demand clean edges and consistent results. The bit is manufactured in the U.S.A. with premium micro-grain carbide, offering durability, longevity, and minimal deflection.
