Ever try to drill holes in bedframe angle iron?
I have and destroyed a bunch of drills. Apparently they use a very hard steel so that they can make them lighter.
Fast forward to today, replacing the floor in an old NI spreader. Needed to drill new holes for the carrage bolts through the angle iron frames under the flooring. Hard drilling. Dulling drills right and left. Even HHS. This AM went back at it with a handfull of fresh sharpened frills. Same results. Did not have any drilling fluid, but I had a can of Conklin Gear Glide (light oil) left over from late FIL's estate, (old stuff). Put a few drops on the drill bit and holes. Won't say anything about butter, but drilling went far faster and easier. Guess I learned something!
