We all use twist drills and sharpening them can be a pain . That is, until a smart person came up with the 4 facet grind method . I do it free hand , I just mark a 59 degree line on the grinder rest but some use complicated jigs and guides . Basically, you grind four flats onto the drill. After sharpening a few times you also need to thin the web , thinning the web narrows the chisel which is the section on the centre tip that doesn't do any cutting at all . Going ahead, you can do the split point grind which provides a sharp tip at the chisel , doing this this greatly reduces the force required to drill through anything
