10" backhoe bucket for Ford 755

I have found that most of the metals that I use hole saws no matter what kind or brand they are simply are trash. even the carbide tipped ones have too short of a service life for their price. Annular cutters for my mag drill are the way to go whenever possible I just don't own a wide range of sizes.
But I have always found that a cutting torch will beat out even the best of them except on non ferrous metals
