    I'm machining though 3" aluminum bar and the longest end mill I have is 2" so it requires 2 different set-ups. looking for a source of extended length end mills . I prefer 2 flute end mills. Any recommendations of where to buy these.

    I did a quick search on the Enco and Victor Machinery web sites. Both have a selection of two flute end mills with 3" long flutes. Do a web search on cutting tools/end mills and I'm sure you will get a lot of cutting tool vendors that have what you need.

    Hope this helps,

    Most all of the normal industrial suppliers have them. Enco, Travers, MSC, etc. I usually just call my local tool supplier and let them track down exactly what I need.

    You didn't say what diameter.........

    oops! 3/8" diameter. that seems to work the best for what I'm doing. Building a Jerry Howell Farm Boy Engine. Lots of fun so far.

    All I can say in emergency situation, call Victor Machine Exchange in NY (by phone). Example I called at 3pm and UPS was here 9AM
    the next day with NO extra shipping charges, and the people there are real freindly and you are not talking to some stupid tape recorder.

    MSC corp. has a selection of long end mills. Call 1-800 645-7270 and ask for a catalog. They're good people to deal with.

    I have bought long length endmills from MSC. The ones I bought are not center cutting, found that out by accident.

    Center cutting with an extended length endmill is just asking for trouble. They tend to wobble then snap.

    Sometimes, Andre, when you are running a ramp in, or spiral in plunge routine on a CNC mill and you need the reach there isn't a lot of choice, and for that they need to be c-c. Not always for "drilling holes" like you would on a manual mill.

    Another forum member turned me on to theses for deep milling. I was getting terrible chatter from an extra long end mill. Not cheap but they work great.

    Mc-master has some with 3" length of cut.

    I have one that's 2" and only use in emergencies as the chatter is horrible.



    That seems like a reasonable solution. Price isn't good if you're only making one but for a short production it'd probably be worth the investment.
