How is the step drill modified? I want to try to make some grips for mine as I love woodworking but am not very good at it but it is as fun as re-loading. I was trying to figure how to make those holes. I was thinking a drill bit and a forstner bit but I now see the light. Just dont know how to modify that bit. Are they for sale?
