    Question Ringing Router Bit

    I read somewhere that 1/4" shank carbide bits tend to ring.

    Boy do they ever! I'm using an Onsrud 52-285 (upcut 2-flute 1/4", 1/4 shank) in 3/4" BCX plywood.

    What is the ringing telling me? Can I reduce it by adjusting feed, rpm, DOC?

    Re: Ringing Router Bit

    Probably too much RPM for the material, or not enough IPM. Basically you are not taking a good cut for each flute on the tool.

    I use single flute cutters on my CNC Router, they work much quieter and give a better chip.

    What RPM, IPM, DOC are you cutting at?

    DOC 6mm, 1200mm/min. 10-12krpm.
    My feed rate is limited, my poor machine design. I haven’ t tested running any faster. I could drop to 8krpm but that is the low limit of my router, I don’t know how well the speed regulator will work.
