  • Tool for flycutter

    Want to mill a flat surface using a small mill (600 watt or 3/4 hp DC motor). Mfrs claimed capacity is 2-1/2 in face mill.

    Trying to decide between a single point flycutter http://busybeetools.ca/cgi-bin/picture10?NTITEM=B090 and this 3-insert carbide http://busybeetools.ca/cgi-bin/pictu...TITEM=B2136MT3.

    The carbide includes the insert bits (3) but the single point uses standard (non-supplied) tool bits.

    I'm thinking "standard tool bits" means lathe tool bits. What shape would I have to grind on the bit?

    Can I expect a smoother finish with the multi-bit carbide?

    If the single point fly cutter and 3-point carbide are set to the same diameter of cut (ie., 2 inches) do I need to adjust the speed/feed/depth of cut of the carbide vs the fly cutter (since, I am thinking, the carbide has 3 cutters vs one)?

    Any other pointers appreciated.

    Thanks.

    Here's a thread at CNCZone that includes a nice image. It's the shape I use.

      Yup, that's what I like also. I put a bit of a radius on the 'bottom' corner to improve the finish. Works a treat.
