***Machinists say that if a job is too difficult then you are using the wrong tool.
And you don't have
to be a machinist to agree.
Remember how much trouble you had that
time trying to remove a screw using the wrong screwdriver, or drilling a
hole with a worn-out drill bit. Not only was the end result pathetic, but
you were left frustrated, swearing you'd never do it again. When it comes
to micro-machining, and especially the manufacture of watch parts, then
using the right tool is essential.

newly arrived tools from Switzerland, I was once again amazed by the beauty
of the polygon cutter. This little baby is used for milling a square
section of the winding stem and, if run at the appropriate speed and with

with a tool that is a work of art itself. Next time I will share a few
photos of this end mill in action – stay tuned!
