Another way to help reducing the drill walking is to use the shorter screw machine length drills instead of the longer jobbers length. As for drilling wood, there are some really fine designs for drills for drilling wood. Most cut the outer fibers of the hole before drilling out the inside leaving a clean splinter free hole. In my old shop we always bough HSS drills with the black finish in bulk envelopes. There were several indexes around the shop, and these were refilled regularly from the envelopes. We did not resharpen our own drills. Without a proper drill sharpening machine, it impossible to get both sides to cut together, which will result in drilling oversized holes. It cost about $4.00 to get a drill sharpened, so the small ones went right into the trash when they were dull. Many of our larger drills were very old. When the sharpening shop ran into a drill that was not HSS they go right into the scrap. They will not sharpen them. Special coated drills were only used for special projects. We did use cutting fluids and kept several different fluids, like lard and kerosene, around for copper and aluminum. The shop did a lot of small parts in brass and 360 high lead free machining brass was always used.
