A Reddit for Machinists of all varieties. From Old School conventional guys, to CNC Programmers, to the up and coming next generation.

This is an operation I haven't attempted before. Are there any special considerations I should know or even taps or an attachment that makes this process easier/better?

This guide has been developed in partnership with NIMS to aid machining students and working professionals in achieving high levels of success on the National Institute for Metalworking Skills (NIMS) Level I certification exams. After receiving technical training, practicing, and demonstrating the competencies, this study guide will help your students determine their level of readiness for the actual NIMS certification exam. The registration process, performance exams, and requirements for the online theory exams are explained. Test-taking strategies are also included. Practice tests, answer keys, and explanations provide the testing candidate insight into the knowledge and skill area being assessed and serve as an extension of the classroom, lab, and on-the-job training previously received. A glossary of terms is also included.
