    I am looking to buy a Indexable carbide dovetail cutter. I did a search and only found reference to the Dorian brand. It wasn't too highly thought of. Does anybody have a indexable dovetail cutter thet they like" The dovetail mis fairly small 60 degree angle 6mm deep, maybe 24mm wide 60mm long.

    ETA: Material is Alum

    Thanks Tim

    Tim,
    I was looking for the same thing at one time not too long ago. I found the same results you did. The dorian style. I will tell you that I had limited time to shop and so I ended up buying the dorian. I was sort of impressed and sort of not impressed. There is a lot of cutting edge contact going on at once while this cutter is cutting because there is no helix, or rake to the inserts. So it pounds like a straight fluted end mill does. I used it for 8620 hot roll. What did impress me was even though I cut kinda slow to minimize the pounding, it lasted quite well and got the jobs done. Inserts still looked quite good. So what I'm saying is for aluminum, this might not be such a bad cutter, but if you have time to shop for a good one, keep looking. Someone must make a better one.

    Thanks Dave K. I have time to shop around, but I've been looking for quite some time. I checked Iscar, Kennametal, and quite a few other manufacturers. The only one I have found is the Dorian. I'm going to the Eastec Tools Show in May. I guess I'll look there for one. Thanks Tim

    AB Tools makes one. I have no idea what they're like, but if it's half as good as their shear hogs it might be pretty decent.

    Photos here of a 60 deg insert cutter a friend and I made a ways back, no dimensions but you can get a pretty good idea from the pics.

    I've not used them myself but a buddy across town uses some of the A&B tools, including their dovetail cutter. I've not seen it in cut but I have seen some of his finished parts (steel). I've never heard him complain about the cutter and believe me, if it's not good, he complains.

    Oops! I see that wesg already provided the link.

    A&B dovetails look good but are too big for my needs. Tim

    Go to our web page and scratch around and you
    should be able to see a pick of one I made. I
    have made smaller ones since. This was designed
    to move metal (225 long cut 30mm deep one side
    at a time in 1 cut 38 seconds in D2. After roughing I wipe the sides with anothe type I made
    to give a mirror finish.)

    This cutter seems to or actually does defy logic
    because the upper row and lower row of inserts
    require totally different cutting speeds. I run
    it 960 rpm and air blast on a manual machine.
    i must have turned over 1/2million usd with it
    so far. I doubt wether a cnc could lick that. I
    have been making cutters for years ( could'nt
    afford em) and that dovetailer must be one of the best. I climb mill with it with the table nipped.

    Just an update. I ended up buying the Dorian dovetail cutter. As mentioned ealier I am cutting Alum. only so...Anyway I'm very happy with it. Finish was good to excellent dovetails run nice & smooth when mated. Again the dovetail is small 6mm deep 24 mm wide 122mm long. I run the thing a slow feeds and take small .5mm depth of cut. Maybe I'm babying it but I just let the ol' Hiedenhain TNC145 chug along and I go work on another machine

    I know this is an old post, but 5th Axis makes an awesome dovetail cutter. I've had good luck with the AB Tools one as well.

    Tim,

    If you email [email protected] my guess is that we could make a special 24mm x 60deg index-able dovetail cutter. Since you are cutting aluminum we would make it 2 or 3 flutes for strength. We do full specials all of the time.

    i use insert cutter just for roughing dovetails. i have seen heavy roughing cause big triangle inserts to rotate or break insert pockets so angle was off.
    .
    just saying on a big dovetail i would avoid taking it all in one pass if it is harder than aluminum
