Spiral O-Flute Router Bit for Aluminium and Plastic

The Onsrud 65-033 is a solid carbide router bit with a 3/8 in cutter diameter and a super spiral O-flute design. It is built for clean chip evacuation in soft materials. The tool targets CNC operators and woodworkers who need smooth finishes without rewelded chips.

Suited for soft-material routing, not for steel

This bit suits shops cutting aluminium, MDF, plastic or wood where upward chip flow prevents melting and recutting. It is not for ferrous metals, hardened alloys or high-temperature superalloys that demand a different flute geometry and coating.
