6” Single Angle Milling Cutter on R8 Stub Arbor

[Parlo]

Those types of cutters are used on large boring mills etc where the rpms go down very slow . Need flood coolant also . This is not a high speed (rpm) cutter by any means and your mill doesn't have the HP to run it . The tool itself will machine dovetails after roughing out , but not with the arbor you are using .

I guess this cutter can only machine male dovetails.

Add to that, most dovetails are 60 degrees and typically are not machined with cutters that large in diameter.

One of the jobs I remember well as an apprentice was the nuclear sub torpedo trays . We ran them on large verticle Cinci mills . We ran corn cob ( roughing end mills ) thru 6 ft of some kind of government supplied un-obtanium stock and then ran a large dovetail cutter thru it . 2 shifts working 12 hrs each . One of the most boring jobs ever . When the cutters finally gave up , they gave up . Remember well how hard it was to reverse the table without damaging the machine .
