Hey All!

I am having a brutal time mitering some tubes at the moment. I am trying to notch a Columbus Zona Megatube (biconical type)down tube and the hole saw keeps snagging on its way through, leaving a VERY poor cut. I am using a Starrett hole saw but I am thinking it might be too coarse (6/8 tooth profile). Any suggestions and advice would be appreciated!

Cheers,
