Yea I know, go get the right ones but I can't so how do I get from 3/4 to 7/8". I put it in the drill press and attacked it with a standard bit and some good quality oil but it aint cutting much. It rather just bevels it some. Can I simply heat the entire cicumference to red a 1/4' or so and do the deed or is there a better way? There are 3 of these blades that need the treatment.
