If you’re an experienced machinist, then no doubt you’ll have this covered. But for those new of you to the profession, this YouTube video created by Learn Engineering gives a clear explanation of how the geometry of a single point cutting tool works when removing material.

No matter how robust and powerful your on-site machining equipment is, if the tool bit isn’t appropriate your results will suffer. Not only should the tool be sharp and inserted securely, having an appreciation of the cutting tool geometry will help you ensure it is right for the job.
