    Default Source of cutters for Microbore R-302 boring head?

    Have the tool and some used cutters but would like to buy 2-4 new cutters for use on mild steel. Source? I spent considerable time websurfing but failed to find new or NOS ones.703aa342-bf6b-4908-9996-81efb0ffa0a6.jpg

    You have to know thread size - like a #7 is 3/4"

    You also have to have the "dial" that goes with the tool

    Yeah I believe there's also a hardened washer and flathead allen bolt that comes in from the backside that locks it all down.

    WARNING WARNING

    While the cutters are bad enough, the essential associated hardware DEFINITELY ain't cheap!

    That appears to be a straight mount, so it requires a 100 count dial. Given the size range, I'd guess it is a #10, or 1" thread. Is it on a 50 taper shank?

    Yes, 50 taper. Have some dials too, will look for the rear-end stuff. Bought a bunch of older stuff that was somewhat scattered among many boxes, so trying to put Humpty Dumpties together again.
