LMB 365 – Day 61

Patterns and shapes in everyday objects can be seen on day 61 of #LMB365 which is a photo of some of the R8 milling collets in the LMB’s Technical Instrumentation Workshop. These hold milling cutters concentric to the spindle in a very tight grip. They are used daily and are now mainly metric by size, although a set of imperial collets are still in use.
