The boring tool for brass-work, here shown, is a standard tool for either roughing out or finishing, both of which duties it will perform equally well. It is bent further round at the end than is the boring-tool for wrought-iron, to prevent it from jarring or chattering. It is a master-tool in every sense of the word. It should be hardened right out, and used with a quick speed and light feed, no matter how deep the cut is. To prevent chattering or jarring when extending far out from the tool-post, or when it is very slight in body, it should have the ton luce depressed toward the cutting edge. When this tool is a stout one, the point may be ground more round, which will make it cut to finer finish.
