The Bit Size option allows you to specify the diameter of the cutter installed in Origin's spindle collet. Three different bits are provided with Origin:
- 1/4" up-cut spiral
- 1/8" up-cut spiral
- V60 engraving bit
All three of these bits appear as presets for quick reference.
Tap OK when ready. Origin will remind you to perform a Z Touch so that Origin can understand the Z height of the new cutter.
Z Touch is explained in more detail in a separate article.
