R8 adapter for annular cutters

[jht1057]

Hello All,

I am looking for an R8 adapter to hold annular cutters for my bridgeport. I have only ever seen one, a year or so ago, and can not remember where. Hoping someone here can point me in the right direction to find one.

What type shank on the cutter, Weldon, MT, straight ?

BGunn,

The shank is 3/4" straight w/ two flats on the shank for set screws.

Ok, Those are Weldon shanks, I may have a couple in the shop. I will look as soon as I can. Also as long as you don't push the cutter to hard you can use a regular collet, just set your feed a little lower and use plenty of coolant/oil. I have done this in a pinch a few times it just depends on the material that you are cutting.

Thank you everyone for your help with my tool search. I did win a nice set of cutters and the holder I was seeking on E-bay a few seconds ago.

Thanks again,

Jim
