Default need help with flange/burring rolls??

hello all, i was going to buy some new roll sets for my pexto rotory machine. I always thought that burring and flange rolls were the same thing, but i see pexto has two different sets. The pictures in the roll chart look the same so iam a little confused as to which ones to buy. The use would be for putting the collar on square to rounds and round work. i have the elbow edge roll that i use now, but at another shop i worked for i recall it being a lot easier to do with burr?flange. 1/4" flange out on the body and 3/8 female on the collar that you hammer over when assembling. forget the proper name.

J-2 i think you would have some luck if you got in touch with Pexto. I'm sure you can find them on thw WWW They would have the best advice. But, there is some pretty good advice @ thesheetmetalshop too dupree

Default Pexto

Hi Jaytwo, welcome to the site. The burring roll you want is a "C" roll part #10120 upper and part #10121 lower.
The flange roll is a "L" roll part #15053 upper and part #15054 lower. What machine are you using-544 622 ?

Would you happen to know if the pexto rolls fit the Niagara rotary? it seems to be like 5/8 threads? the Lower roll is a left hand thread & upper roll I think is a right hand thread ?

No, I just purchased a Niagra rotary machine and see that Pexto and Niagra are not interchangeable. Pexto has a roll nut and Niagra Threads directly off the spindle. Also roll wrenches are different.
