1/8" V-End coated engraving bit:
This engraving bit is great for softwoods and aluminum engraving. In aluminum keep a very light contact, and mid RPM range. Soft woods one can be a little more aggressive but would not go over 20% cut length per pass for long life.
Use this if you plan on adding text or anything that requires sharp, small lines or details in your design. The contact line can be as sharp as .2mm.
