    Default Onsrud Super O upcut

    I remember having a 1/4" Onsrud Super O single flute upcut bit that had a 1 7/8" cut length. I can't seem to find that bit anymore. Does anyone know if they still make it?

    the upcut super o flute is the 65-000 series, but the max cut length in 1/4" is 1.5" (65-027)

    Do they make a 3/8" with a deeper cut capability?

    you don't need a full cut length. just make sure your passes are no more then the cutting lengths.

    The issue I'm running into is finding a 1/4" bit long enough, overall, to cut thru 2" of material. I think I will need a bit 3.5" - 4" in length.

    Gary,

    What are the bit speeds (spindle) and feed rates for this bit? Cutting cherry and alder and at times MDF (prototype work).

    our going to get flex with this bit 0-flutes tend to be worse about this. so plan on some cleanup passes. I would not push it too much to keep the bit from breaking. 1/4" pass 3ips is ok. maybe two or three passes on the finish to keep the flex down.
