Quick discussion about drill bit sizing from Chapter 24 in the Modern Metalworking textbook. Drill bits are measured in four ways: Numbers, Letters, Inches & Fractions, and Metric. Watch the video, and if you have any questions you can email me.

This is one of the best explanations of drill bit sizes that I have found, and I searched the web for hours. It's methodical and straightforward. Well worth watching! Thanks, Peter.

Thank you very helpful just what I needed
One minor correction: an inch is not approximately 25.4 mm. It is in fact exactly, precisely, 25.4 mm. The inch was in fact *defined* as 25.4 mm in 1959.
