  1. My machinist friend never uses a drill bit right out of the box. 50+years experience. He grinds them sharper...because factory sharpening IS A JOKE. The machinist drills through tons of metal so he knows how to hand sharpen the drill on the grindstone. No specific make. I learned how to do it once in school - have forgotten that talent and always have one flute edge cutting more than the other. When you had to add more weight, I could see the point was not cutting anymore...so the drills are dull. Most of my drill bits cut into wood okay and even aluminum or copper. Steel is marginal.

  2. Nope. A machinist would FIRST sharpen the drill bit. Those that needed more weight, were already dull on the point edge "it has a specific name and a specific angle. Forgotten over the years. Most of my twist bits are decent for copper, aluminum, brass, lead wood, plastic & soft fudgsicle.
