Oklahoma | Forgive me for being an idiot at alot of things but can someone educate me in drill bits. Who makes "good" drill bits? What do you look for?
A few years ago, I was given a set of bits, I think Buffalo brand. I was told when I got them, these are the best bits you can buy. I have used them on woodworking projects and occasional metal. My problem is that I can drill for about 5 minutes in metal and they quit cutting. I have seen people drill everyway that seem imaginable and they seem to get bits to cut through metal (steady pressure with oil, without oil, drill a couple seconds then let off, redrill, doesn't seem to matter the shavings are flying). Yesterday tried drilling a through a 1/8" piece of metal with 1/4 inch bit that hadn't ever been used. I started the hole and got it set, then oiled it and had it cut down to about a full bit size. The bit quit cutting. I let it set, tried again, wouldn't cut, let sit, tried again, this time I got ticked and put "some pressure" on it and that didn't help. Before it was over, the bit bent of course but I still hadn't gotten it to cut. In wood these bits work alright but metal they seem to go dull in a couple minutes. How long should a good bit hold an edge pending a good operator? What is considered a good way to drill metal? Is this operator error on mine or poor bits?
Thanks.
