Sorry for taking so long to reply back. I received the carbide annular cutters from Jantzy and tryed one this morning - worked like a charm. The reason for cutting new holes - i sold my Miskin pull pans , but still have many New edges left , all my John Deere pull pans use a different bolt pattern as well as size bolt. To much money sitting around to not use them. I also didnt want to drill extra holes in the pan and possibly weaken it / with 500 hp pulling it , its hard enough keeping them together and not pulling them to peices.
I will use standard bolts with these edges due to no way or need to cut holes for carriage heads. It will be a little more time consuming to install with hex heads , but once they are used up its back to original ones agian, they will be gr # 8 and i welded a peice of flat bar in front of the bolt to keep the heads from wearing off.
Thanks for all the input to solving this , it cost a couple bits but atleast they r done.
TOM V - thanks for helping and your time as well - i and my machine shop still dont understand why your cutters would not work , they would get about 1/32" into the plate and stop cutting. The Carbide did very good tho. thanks.
