[QUOTE="Trickymissfit, post: 1125538, member: 25383"] had to drill and tap years back I was building a very large robotic cell (it is still the largest in the world). I had to drill and tap a hundred or so 1.06-16 thread holes. So I had the boss order in a dozen taps, and drills and reamers. I asked for machine taps (I didn't have an apprentice to hand tap all these holes<g>!) A box of stuff showed up, and I went to work on a big radial drill press (I was there for the better part of a week). Here comes the boss, and he's white as a sheet! He's got the bill in his hands for the drills and taps. Each one was a tick under $150!! The bill was a little over four grand. A week or two later I got a similar project for leveling screws on the same project. This time about two hundred of them, and they're 1.50-16 tpi threads. I had a similar tap on hand, and asked the folks if they could re-sharpen them. They could, so I only ordered in four taps, and the needed drills and reamers (good idea to ream the hole on big fine threads). The bill for those taps were $350 a piece!
