There was recently a thread about drilling in sheet or plate steel, but I don't want to hijack that thread, so starting a different one here.
I need to drill a few 1 inch diameter holes in 1/8" and 3/16" steel plate. Right now my only choices on brand and type are limited since we live in a rural area. I was wondering what you guys have used that cut best and have durability for BI-METAL 1" hole saws. I'll be using them on my drill press with the lowest speed and lube. I don't have access to plasma, CNC, O/A, etc.
My local brand choices are limited to:
If I want to go with carbide hole saws and maybe include Lenox bi-metal, I have to drive 90 miles round trip (add $20 for gas). If I gotta do that, then I'll order online.
