lol crank, but I’m not sure I want to kill my files. Than again, my files are antique too, so that probably won’t work with what I have on hand, they probably wouldn’t qualify with what you define as a cheap file. Guess I’d have to go to HF to buy a cheap file. TSC? Tractor Supply? The cobalt drills bits are extremely expensive, and I’m mostly interested in working with wood right now. Interesting enough, I have no brad point bits, my father never bought any even though he worked only with wood. I can only assume they weren’t invented in his lifetime or he would have had them rather than standard twist drill bits. He died when I was 17. I been websurfing various places getting a feel for the price of them, think I want a set but will probably watch and wait awhile and see if I can’t pick up a sale item from someone like rockler, woodcraft, amazon etc. I didn’t know harbor freight carried cobalt steel bits, seems kind of high end for them. I do know that the bits I have are useless for drilling steel of any kind. I’ve tried in the past and it a no go. Now it may be they too dull. It didn’t seem to damage them, it just wasn’t possible. They do fine thru wood though. I would like to be able to drill thru steel. Not necessary for any super stainless titanium type alloys, but for instance into my utility trailer to add features. Pefect example is my new tractor supply trailer has the license plate mount in a really stupid place that as soon as I hit a good bump, the license plate and it’s sturdy plastic mount will probably go Bye Bye. That definately could use a revision.
